You may not always know where you are, but your phone does. By now, most of us have noticed that our smart phones are extremely effective at tracking our whereabouts. Open a map application, and a pin automatically appears creeping slowly along the road where you are driving. Use the internet to search for a hardware store and the phone will list web links, maps and phone numbers for the three closest to you. Beginning this summer, you might even be surprised to find your phone giving you a reminder as you pull into a local boat launch – clean your boat, before and after getting on the water, to prevent the spread of aquatic invasive species.

Aquatic invasive species are plants and animals, not native to Minnesota, that threaten the health of our rivers, lakes and streams and cause millions of dollars of problems for local communities. Well known invasives include zebra mussels, carp, Eurasian watermilfoil, and curly-leaf pondweed. Once introduced to a body of water, they typically spread quickly and are expensive and nearly impossible to remove.  To prevent the spread of aquatic invasives, the law requires all boaters to clean and drain boats, trailers and other equipment after coming out of the water, and to dispose of unwanted bait, including minnows, in the trash.

On June 10-11, PLM Lake and Land Management Corp. applied herbicide to control invasive Eurasian watermilfoil in Big Marine Lake.

Last year, the Minnesota Legislature allocated funding to counties to implement aquatic invasive prevention and education activities. Washington County was allotted $202,392, which they have passed through to several local entities for projects in 2015, including herbicide treatment of invasive Eurasian watermilfoil in Big Marine, Long, Jane, Demontreville and Olson Lakes, herbicide treatment and cutting of flowering rush on Forest Lake, and watercraft inspectors to monitor boat launches and water access points during summer boating and fall waterfowl hunting. In addition, the Washington Conservation District is working with partners to improve signage at popular boat launches and educate boaters and waterfowl hunters about what they can do to prevent the spread of aquatic invasives. That’s where the telephone location technology comes in handy.

Public service announcements are being targeted to mobile devices near popular water bodies in the county to catch the attention of visitors, as well as local residents. If you check the weather while you’re out fishing on Big Marine Lake, you might see a banner ad urging you to “Save the fish..and then eat them.” Click to confirm, “Yes – I cleaned my boat today,” and you’ll be directed to a webpage with information about aquatic invasive species and a list of infested water bodies in the county. Taking it one step further, people can even upload a picture to Facebook, Twitter or Instagram with the hashtag #SavetheFishMN to help spread the word and be entered into a contest with prizes from local businesses.

In addition to funding immediate actions to address the threat of aquatic invasives, Washington County is also supporting the St. Croix River Association, which recently hired a full-time invasive species coordinator and is working with governmental and community partners in Minnesota and Wisconsin to create an aquatic invasive species plan for the entire St. Croix River Basin. The plan will include detailed strategies for prevention; research and monitoring; control of new and existing infestations; and evaluation.

If you like fishing, boating, swimming or hunting on local lakes and rivers and you want to be part of the resistance force working to block aquatic invasives you can do three simple things: 1) Clean, drain and dry your boat and equipment before and after getting on the water; 2) Help spread the word to friends and family – #SavetheFishMN; and, 3) Come to a public meeting hosted by the St. Croix River Association on Thursday, July 9, 4-6pm in the Washington County Government Center in Stillwater, Lower Level room 14, to share your ideas and input about aquatic invasives in the St. Croix Basin.

Measuring progress toward cleaner lakes and streams in Washington County

In 1938, the first major wastewater treatment plant was built on the Mississippi River in Minnesota at Pig’s Eye Lake in St. Paul. Prior to that, thousands of homes in Minneapolis and St. Paul had been literally dumping dirty toilet water straight into the river, which was incredibly polluted and smelled so bad that no one wanted to live near the water. According to the Metropolitan Council, “Within four months of the treatment plant opening, the floating mats of stinking sludge and scum were gone. Within two years, fish returned to metro waters and anglers reported catching walleye and other game fish in water that previously could not support carp.”

After the Clean Water Act was reorganized and expanded in 1972, the nation saw similarly huge leaps in water quality in many rivers and lakes. Within a few years, factories that had previously dumped toxic chemicals and untreated waste straight into nearby waterways began employing new technology to clean up their discharges. Improvements in lake and river health were quickly visible.

The new Washington County project map shows where urban and rural clean water projects are located.

The new Washington County project map shows where urban and rural clean water projects are located.

In recent decades, however, our attention has turned from “point sources” of pollution, like factories and wastewater treatment plants, to “non-point sources,” like urban stormwater and agricultural runoff. This makes it increasingly difficult to measure and keep track of our progress toward clean water, even when we have monitoring programs in place to measure surface water quality.

One solution in Washington County is a new web-based mapping tool that tracks small-scale habitat and water improvement projects that reduce non-point source water pollution. Created by the Washington Conservation District, in partnership with Washington County, as well as Brown’s Creek, Carnelian – Marine – St. Croix, Comfort Lake – Forest Lake, South Washington and Valley Branch Watershed Districts, and the Middle St. Croix Watershed Management Organization, the tool helps to visually show where projects have been installed and can also be used to measure progress toward big goals, like restoring the St. Croix River. “Currently, there are data points for more than 1,200 voluntary urban and rural conservation projects installed in Washington County since 2005 – a real accomplishment,” said Jay Riggs, Conservation District Manager.

If you are interested in seeing where conservation projects are happening in your neighborhood, explore the new Washington County project map at The map includes layers for both urban and agricultural practices.

If you don’t find much in your area, don’t worry. Your project can be the first.

South Washington Watershed District adapts to changing times and new challenges

When the South Washington Watershed District (then called the Cottage Grove Ravine Watershed District) was first established in 1993, its primary objective was to protect against flooding in Woodbury and Cottage Grove. Since then, the district’s boundaries have expanded along with its mission, which now includes protecting and restoring area lakes and the Mississippi and St. Croix Rivers, conserving groundwater resources, and helping local communities to adapt to a changing climate with more frequent, higher intensity storms.

Encompassing 110 square miles at the confluence of the Mississippi and St. Croix Rivers, the South Washington Watershed District includes all of Cottage Grove, St. Paul Park, Newport, Denmark Twp. and Grey Cloud Twp., as well as portions of Woodbury, Oakdale, Lake Elmo and Afton. Included in this area are twelve lakes and 2,400 acres of wetlands.

New development continues to be one of the biggest challenge facing the watershed; what was once prairie, savanna, and forest has now been converted to suburban development, and farming has radically changed the landscape even in the parts of the district that remain rural. These changes mean more water running off the land when it rains, less water soaking in to recharge shallow and deep groundwater aquifers, and more pressure on the groundwater resources people use for drinking and irrigation.

On the edge of development in southern Washington County.

On the edge of development in southern Washington County.

When the South Washington Watershed District was first formed, a large segment of the watershed covering Oakdale, Lake Elmo and Woodbury was draining to one little lake – Bailey Lake, which had no controlled outlet.  Localized flooding was already a problem in some neighborhoods, and the local communities knew the problem would get worse as development continued.  To protect homes and businesses, the watershed district purchased 250 acres of land near the outlet of Bailey Lake and constructed what is now known as the Central Draw Storage Facility – essentially a large, bowl shaped meadow that can temporarily fill with water like a small lake when Bailey Lake overflows. Currently, the district is proceeding with later phases of the flood-prevention project, scheduled to be complete in 2020, which involves building a series of pipes and dry streams to carry overflow water from the Central Draw down to the Mississippi River in the event of a 100 or 500-year mega-storm.

Along with a heightened risk of flooding, changes in land use in southern Washington County have degraded water quality in area lakes as well. Rain and melting snow wash off of farm fields, roads and parking lots, carrying sediment, nutrients and pollutants into ditches and storm sewers that connect to area waterways. As a result, the lakes have less fish than they used to and suffer from algae blooms during the summer.

During the past twenty years, city, state and watershed district rules have helped to reduce polluted runoff from construction sites and limit stormwater runoff from developed areas as well. As a result, water quality in area lakes and wetlands is no longer getting worse. Now, the South Washington Watershed District is increasingly looking for opportunities to retrofit already developed areas and pursuing “in-lake” strategies to remove pollution already in the water as well. One such project was a neighborhood retrofit near Colby Lake, in which the district built 25 residential raingardens to capture and clean stormwater runoff from local streets. Industrial sized raingardens can also be seen at the Bielenberg Sports Center and the South Washington County Service Center.

The South Washington Watershed District is currently developing a new 10-year plan that will guide its work from 2016-2026. The Watershed District board will review recommendations from staff and advisory committees at a special meeting on Tuesday, June 23, 6-8pm at the Woodbury Public Works building, and they are also hoping to get feedback from people who live and work in the watershed. To provide input, attend the upcoming meeting or contact John Loomis at 651‐714‐3714 or Additional information is available at

Drought, floods and hail – oh my!


Posted by Angie Hong | Posted in Uncategorized | Posted on 11-05-2015

‘Dat was some pretty darn big hail we had last weekend, hey? It was especially dramatic for those of us that didn’t bike quite fast enough to make it home before the storm started (spoiler alert – we lived). Then again, the wind and hail was nothing compared to that other storm that happened that one time way back when, right?

If you’ve lived in Minnesota or Wisconsin for more than a year, you know that unpredictable weather is one thing you can count on around here. The temperature can swing more than 50° from one day to the next, and it’s entirely possible to have hyper-local storms that dump rain and hail in one area, without so much as a drop of rain in a nearby community only a few miles away. For as long as people have been tracking the weather in our region, there have been blizzards and thunderstorms, drought and floods, tornadoes and heat waves. Despite this predictable unpredictability, however, scientists have noticed that typical weather patterns in the upper Midwest are not entirely the same as they used to be.

During his keynote talk for the St. Croix Summit on April 29, Minnesota Climatologist Mark Seeley talked about the kinds of weather information researchers gather and the changes they’ve seen over time. For example, though Minnesota has always suffered from severe thunderstorms and occasional “mega rain events,” these kinds of storms have actually become more frequent in recent years. During the first 140 years that people were recording weather information in Minnesota, there were seven mega-storms – an average of one every 20 years. In the past 15 years, there have already been five mega-storms – an average of one every three years! Most of us can remember these large storms vividly because of the damage they caused; they include events such as the flooding in Duluth, June 19-20, 2012 and the storm that dumped 15-17 inches of rain on southeast Minnesota, August 18-19, 2007, flooding the Whitewater River.

In general, we are getting more of our rainfall from thunderstorms nowadays, and less from plain ol’ boring, drizzly rain. According to Seeley, 75% of the precipitation in southeast and eastern Minnesota in 2004 and 2009 came from thunderstorms. In between these storms, there are often extended periods without any rain. As a result, many communities find themselves in the unusual position of battling floods in localized areas, while still under drought conditions as a whole.

Clean your neighborhood storm drains after storms to help keep the street from flooding and keep nutrients out of local lakes and rivers.

Clean your neighborhood storm drains after storms to help keep the street from flooding and keep nutrients out of local lakes and rivers.

Last Sunday’s storm in Stillwater demonstrated how easily that can happen. During the worst of the hailstorm, I watched torrents of icy stormwater rushing down one of the city streets toward Lake McKusick. The water was moving so fast that most of it swept right past the storm drains, flooding McKusick Rd. at the bottom of the hill. The next day, as I was sweeping leaves and twigs up from our sidewalk and driveway, though, I noticed that our gardens were still bone dry.

City planners and engineers use rainfall data from the National Oceanic and Atmospheric Administration (NOAA) to determine how big to make stormwater pipes and ponds to prevent flooding in our communities.  Until recently, the standards were based on weather data collected during the first half of the 1900’s, including the 1930’s Dust Bowl Era. When the standards were updated in 2013 to include rainfall data since 1961, engineers realized that the average 50 and 100-year storms had increased by 20-25% in many parts of Minnesota. As a result, the new 100-year rain event is more like what we used to call a 200-year storm. These very large storms quickly overwhelm older stormwater pipes and ponds and, because the ground gets too saturated to absorb more rain, there is usually lots of runoff. The best ways communities can protect themselves from flooding damage due to increasingly frequent large storms are to preserve wetlands and open space in flood prone areas, and create larger easements and safe overflow routes for stormwater ponds and ditches.

There’s a reason FiveThirtyEight Science just ranked Minneapolis as one of the top three major U.S. cities with the most unpredictable weather. As the saying goes around here, “If you don’t like the weather, wait five minutes and it will change.” To protect yourself from hail damage as severe storms become increasingly frequent, consider my advice. Start carrying a bike helmet with you at all times, just in case a storm rolls in.

Planting for Future Generations

Charlie collects worms and feathers along the way.

Charlie collects worms and feathers along the way.

When he starts kindergarten in two years, the young baby oaks we planted last week will still be shorter than he is. They’ll continue growing slowly, maybe a foot each year, so that they’ll finally be taller than he is by the time he gets his driver’s license, though still too skinny for him to carve his initials alongside another’s in a heart. By the time the oaks are sturdy and tall enough for me to sit and rest my back against, he may already have kids of his own. Perhaps I’ll bring them to visit the trees and gather up acorns to bring home and plant in their yard. Many, many years from now, when his grandchildren have grandchildren of their own, those trees that we helped to plant on Arbor Day of 2015 will finally stand tall and proud with gnarled limbs and massive canopies, roots anchored deep in the prairie. By then, no one will remember who planted the trees or know that we patted the soil beside each seedling, whispering words of encouragement, “Grow big little buddy.”

In a world of instant gratification, planting a tree is still an immensely satisfying experience. This past week, Great River Greening brought together nearly 200 volunteers to plant 3000 young oaks, grown from acorns, in the South Washington Conservation Corridor in Woodbury. Little by little, the South Washington Watershed District is restoring the land, set aside to provide food relief and infiltrate stormwater runoff from the city, to native prairie and oak savanna. Eventually the site will feature an interpretive center, as well as trails helping to connect Lake Elmo Park Reserve all the way down to the Mississippi River.

200 volunteers planted 3000 trees

In spite of cold weather and light drizzle this Arbor Day, volunteers still turned out in mass for the tree planting event. We brought a small team from the Washington Conservation District, including my son Charlie – age three, and a co-worker’s daughter Linnea – age two. County Commissioners Lisa Weik and Karla Bigham spoke during the pre-planting ceremony, as did Watershed District managers Jack Lavold and

Denny Hanna. Other volunteers included teams from local businesses, as well as area residents who signed up as families and individuals. Charlie and Linnea provided a distraction from the chilling rain, helping to tie little blue ribbons around the new seedlings and collecting earthworms along the way. By the time the oaks we planted begin to produce acorns, Charlie and Linnea will already be in their 30’s, with jobs and lives of their own.

Bur oaks are incredibly well adapted for life on the prairie. Though they grow slowly, their tap roots burrow down more than four feet within their first year, helping them to hold ground against similarly deep-rooted prairie plants. They can survive fires and even lightning. In fact, it is often impossible to tell how old a bur oak is by counting its rings because most of the older oaks have burnt and hollowed inner trunks from the repeated lightning strikes they’ve suffered.

The baby oaks were barely large enough to see.

The baby oaks were barely large enough to see in the field.

American Forests calculates that a mature bur oak tree 60 feet tall and 105 feet wide with a circumference of 322 inches removes 19.56 lbs. of nitrogen, sulfur, ozone and particulate matter every year, and if planted in a built environment, can provide $3456.39 in stormwater control (by intercepting rainfall that would otherwise runoff into a storm sewer system). According to ecologist and author Doug Tallamy, they also support more than 500 species of larval insects, which in turn, provide food for song birds and other animals. They are slow growing, but long lived, reaching heights of 70-80 feet, on average, and sometimes living more than 400 years.

What will Woodbury look like when the young oaks we planted last week stand tall in groves upon the prairie? Who will pause to explore beneath them while out on a family picnic? What challenges will those future generations face and where will they plant their trees?

The release of Hector the Toad

Hector awaits his release.

Hector awaits his release.

It happened in the blink of an eye early last fall. One minute I was mowing the lawn, and the next a small, greenish figure was struggling in the grass. My heart sank. It was a toad. I rushed to pick it up and noted with relief that I had only clipped one of the front legs, amputating it at the “knee.” Other than that, the toad seemed remarkably well. (Other than that, Mrs. Lincoln, how was the play?) Since the accident was my fault, I felt obliged to bring the toad inside and care for it for a while, in the hopes it might recover and go on to live a normal amphibian life.

Soon Hector, as my son named him/her, was well equipped indoors with a small aquarium, a shallow bowl of water and a nice hollow rock to hide under. For a few days, I applied a repti-healing aid to Hector’s leg with a Q-tip, and Charlie and I foraged in the gardens to bring the toad a steady supply of tasty worms and bugs. When the weather turned frosty, we switched over to mealworms from the pet store. Never once did we see Hector eat a single bite of worm, and in fact, he spent the entire winter hidden under the rock so that several days would go by before I would suddenly remember we had a pet toad and rush over to see if he was still alive.

Then one day recently, I passed through the dining room and noticed that Hector was out and about, alertly sitting on a pinecone. The next day, he was out as well. “I think Hector is done hibernating,” my husband remarked later that week. My son and I agreed we would set Hector free in the backyard as soon as the weather got a little bit warmer. A few weeks later, the chorus frogs and spring peepers began calling outside.

At a meeting recently, I asked people to share their favorite signs of spring. Some people look forward to specific activities – watching the baseball season opener or going outside without any socks. Other people look for buds on trees or tulip bulbs coming up in the gardens. For many though, spring announces itself with a chorus of sounds – frogs trilling, redwing blackbirds calling, and geese honking overhead.

During the spring, seasonal ponds and streams seem to appear out of nowhere. Sometimes called vernal ponds or ephemeral wetlands, they form in low-lying areas on the landscape when spring weather brings melting snow and lots of rain. Although these wetlands are temporary, they provide important habitat for migratory birds, amphibians and even insects like dragonflies. Pollution from fertilizers and pesticides can have a particularly bad impact on ephemeral wetlands during the spring when frog and toad eggs are hatching into tadpoles and birds are stopping over on their return journey north. Retaining a buffer of unmowed native plants around ephemeral ponds and streams helps to protect them from harm and using less chemicals on nearby lawns helps as well.

This past weekend, we decided it was finally time to say goodbye to Hector. We carried him outside and my son helped to choose a place in the back corner of our yard in a shady, hillside garden under some trees. After a few false starts, I finally convinced Hector to hop out of the aquarium and then I placed his hollow rock over him for protection. An hour later, when Charlie led my mom and a couple of friends over to show them where Hector was hiding, we all gasped in horror when we found the fake rock lying upside down in the lawn – the dog! Then, out of the corner of my eye, I saw a greenish figure hopping up the hillside. Gently, I scooped Hector up and moved him and his rock to the other side of the fence. He may not live forever, but today the toad is still safe.

Get involved and make a difference for Earth Day and Arbor Day

Toward the end of March, I heard my first redwing blackbirds of the spring calling from the cattails. By early April, frogs were trilling in the wetlands. The strawberry leaves have begun to green-up in the garden and tulip and daffodils are emerging throughout my neighborhood. Though winter struggles mightily to hang on, spring steadfastly marches on, bit by bit, day by day. This week, community events planned in honor of Arbor Day and Earth Day will give people the opportunity to get outside, celebrate the spring, and make the world a little bit better.

Arbor Day is an annual celebration of trees first observed in Nebraska in 1872. Today, Arbor Day is celebrated across the United States on the last Friday in April. “The simple act of planting a tree represents a belief that the tree will grow and, some day, provide wood products, wildlife habitat, erosion control, shelter from the wind and sun, beauty, and inspiration for ourselves and our children,” says the National Arbor Day Foundation.

The first Earth Day, held in 1970, brought 20 million Americans out into streets, parks, and auditoriums across the country to demonstrate for a healthy, sustainable environment. Gaylord Nelson, then a U.S. Senator from Wisconsin, is credited for initiating the event after witnessing the impacts of a massive oil spill in Santa Barbara, California in 1969. Nelson reached across political divides to convince national and state leaders that protecting the environment was in the nation’s best interest. Today, the Earth Day Network coordinates Earth Day events around the world, and thousands of community groups organize their own activities as well.

Locally, Great River Greening and the South Washington Watershed District will bring together more than 200 volunteers on Friday, April 24, to plant 3,000 oak trees in the South Washington Conservation Corridor between Woodbury and Cottage Grove, in part as a celebration of Arbor Day. The South Washington Conservation Corridor connects open space between Colby Lake in Woodbury, Cottage Grove Ravine Regional Park, and the Mississippi River. Within the corridor, the Watershed District has built a regional stormwater infiltration basin to help recharge groundwater and prevent flooding in Woodbury and Cottage Grove, and has also worked with both cities to manage stormwater runoff from new development. The 80-acre parcel in which the planting event will take place will provide critical native habitat for south-central Washington County and will be the site of future recreational trails.

The next day, on Saturday, April 25, Mahtomedi will be holding its 9th annual RITE of Spring Earth Day event, 9am-noon at the Mahtomedi District Education Center (1520 Mahtomedi Avenue). Mahtomedi’s RITE of Spring is a free family-friendly event sponsored by Mahtomedi Community Education, Mahtomedi Garden Club, City of Mahtomedi, MAGI (Mahtomedi Area Green Initiative), community volunteers and local churches. Events and activities will include a Bike Safety Check and Rodeo for the kids, a room full of hands-on water activities, composting workshops, electronics recycling, and a drop-off for unused medications. As a bonus, people who attend can register to win a free water efficient toilet. For questions, call 651-426-3344.

In addition to these and other local community events, the Washington Conservation District and Recycling Association of Minnesota will be distributing pre-ordered trees, rain barrels and compost bins at the Washington County Fairgrounds on Friday April 24, 8am-8pm and Saturday, April 25, 8am-noon. Extra stock will be sold on a first come, first served basis at the event.

Your Lawn Care Personality, Decoded

Healthy lawns are safe for wildlife and pets.

Healthy lawns are safe for wildlife and pets.

Which of the following best describes your relationship with your yard? A) Most days, I’m just hoping to get out the door wearing a clean pair of pants and matching socks on both feet. I would like to spend the least amount of effort possible on my yard to avert public scorn and avoid poisoning children and small mammals. B) I don’t want to spend a ton of money, but I really do want my lawn to look nice. Though I’d like to be as environmentally conscious as possible, I’m not about to crawl around on my hands and knees picking crab grass and dandelions all day. C) I envision my yard as an oasis where my family and I can frolic and relax while joyfully providing nectar and habitat for passing birds and butterflies.

Early in the 20th century, the Garden Club of America encouraged uniformity in the suburban landscape, calling for tidy lawns “with a single type of grass with no intruding weeds, kept mown at a height of an inch and a half, uniformly green, and neatly edged.” Today’s modern society values diversity, however, so it’s more realistic to expect that our yards will reflect, rather than conceal, our different personalities, preferences and lifestyles.  Furthermore, we live busy lives nowadays. Though we may like the idea of lush green grass in theory, the reality is that most of us aren’t willing to spend the time or money necessary to actually achieve a “perfect” lawn. In addition, we’re more aware of the potential impacts our yards can have on our health and the wellbeing of the environment. We want lawns that are safe for our kids and pets, and we also want healthy landscapes that support pollinators, birds and wildlife. We’re worried about the St. Croix River and local lakes, and also want to ensure that groundwater resources remain plentiful for future generations.

It occurred to me recently that you can categorize most healthy lawn care practices in one of three ways: 1) Simple changes that are free and don’t take extra time; 2) Low-cost, low-effort actions that can give you a better looking lawn and might save money in the long run; and 3) Bonus projects that will take a little more work, but will help to turn your yard into an oasis. Coincidentally, these categories line up well with the three lawn care personalities I described previously.

A "perfect" lawn? Or perfect for your family?

A “perfect” lawn? Or perfect for your family?

If, for example, you work full time, have two school-aged children and run 5K races on the weekends, you probably don’t have time to do more for your yard than occasionally mow the lawn. Even so, you can have healthier grass that needs less water and is more resistant to weeds, simply by setting your mower blade higher to three or four inches (3-4in tall), instead of one or two. Mow less frequently or skip it altogether during long, dry spells in the summer, and leave the grass clippings on the lawn to act as natural fertilizer. If you have an automated sprinkler system, turn it off so that you aren’t wasting water when it isn’t needed and turn the sprinklers on manually only if the lawn really needs it.

If you have a little more time on your hands and really want a vibrant lawn, look for low-cost options that will improve the health of your grass without impacting the environment. Get your soil tested before applying fertilizer to ensure that you’re applying the correct type and amount for your yard’s conditions ($17 for a test by the University of MN, Install a rain sensor or soil moisture sensor on your irrigation system and program it to give your lawn no more than one inch (1in.) of water per week, including rain. Aerate your lawn once per year to help break up compacted soil. Avoid “weed and feed” mixes or broadcast applications of herbicide across the entire lawn; instead, spot treat weeds as needed. If you’re hiring someone else to do the work, download “What to ask for from your lawn care provider” ( as a guide.

Last, but not least, if you are a nature-lover or gardener at heart, you probably already have hopes that your yard will one day be more than just a lawn. Challenge yourself to begin gradually removing the parts of your lawn that you don’t use and replace them with trees, shrubs, gardens and native plantings. Instead of attempting to transform your yard in one summer, try to do one new project per year and start with the areas that currently give you the most heartache. For example, plant a shady groundcover under a tree instead of killing yourself trying to grow grass in the shade. Over time, these plantings will bring multiple benefits to your yard, including adding beauty, improving habitat for pollinators and wildlife, reducing water runoff, and creating visual screening. To learn more about landscaping with native plants, visit or or contact the Washington Conservation District (651-330-8220) to schedule a free site visit and learn about grants for clean-water planting projects.

To learn more about healthy, beautiful lawns for busy people, come to one of two upcoming Healthy Lawn Workshops, Tue. April 21, 6-8pm at Central Park in Woodbury or Tuesday, April 28, 6-7pm at Hugo City Hall. Details at:

St. Croix River: Changing Climate, Changing Times

St. Croix River at St. Croix State Park

St. Croix River at St. Croix State Park, MN

How would you describe the St. Croix Basin if you were speaking to a visitor from another part of the country? Would you talk about the charming and vibrant small towns along the lower stretch of the river, where restaurants are plentiful and arts and culture abound? Or would you talk about the cabin culture in the northwoods around Hayward, WI, where the summer days are endless and everyone has a boat? Perhaps you would speak of the fertile farm land in Western Wisconsin or the dense woods in Minnesota’s St. Croix and Nemadji State Forests?

Within the 7760 square miles of Minnesota and Wisconsin that comprise the St. Croix Basin, you can find a National Park, National Forest, and National Refuge, portions of two National Scenic Trails, three National Historic Landmarks, 12 State Parks, eight State Trails, six State Historic Sites, 10 State Forests, 65 State Natural Areas, more than 150 properties listed in the National Register of Historic Places, the St. Croix Scenic Byway, and resources associated with four Ojibwe bands that have tribal lands within the watershed. Though the landscape and communities within the basin are diverse, the St. Croix River brings them all together.

The 2015 St. Croix Summit, scheduled for Wednesday, April 29 at the Water Street Inn in Stillwater, will be an opportunity for citizens, scientists, policy makers and local implementers from throughout the basin to engage in a full day of learning and collaboration. This year’s Summit will be a re-invention of the St. Croix Basin Conference that has been held annually for 15 years, thanks to an enhanced partnership between the St. Croix Basin Team, an intergovernmental partnership, and the St. Croix River Association, a non-profit organization dedicated to protecting, restoring and celebrating the St. Croix River. Though the conference will still retain an emphasis on protecting the river and improving water quality, this year’s speakers will also discuss some of the many other factors that impact humans and ecosystems in the St. Croix River Basin. In addition, the St. Croix River Association will hold its Annual Gathering in the evening, allowing people who wish to attend both events.

Titled Changing Climate, Changing Times; Reaching New Audiences, the St. Croix Summit will feature a keynote presentation by Mark Seeley, climatologist with the University of Minnesota, along with several shorter presentations about the ways that climate change may impact water resources, forests, and city stormwater and flood planning in the St. Croix Basin.

Presenters will also offer suggestions for how public entities and nonprofit organizations working to protect and improve the river can better engage the public. Afternoon keynote Ryan T. O’Connor, Ramsey County Policy and Planning, will talk about the changing demographics in the upper Midwest and strategies for ensuring that our outdoor parks and spaces are as vital to our communities tomorrow as they are today. There will also be examples from around the Basin of the unique ways that people connect with the river, including kayaking with the Lac Courte Oreilles Boys and Girls Club, an initiative of the National Park Service; New Light Under the Surface: Underwater Photography and The Healing Power of a River; and the St. Croix River Valley Art Bench Trail, an ongoing community art project that engages local groups in designing, locating and creating art installations in public spaces.

In the evening, Wisconsin author Bill Berry will talk about his book “Banning DDT: How Citizen Activists in Wisconsin Led the Way”, an inspiring story about average citizens who joined with scientists to wage one of the first and most important battles to the modern environmental era.

A sign that this year’s St. Croix Summit is evolving from a professional research conference into an event with broader appeal are the arts elements that will be woven in throughout the day. In the morning and early afternoon, local artist Susan Armington will introduce the importance of art in connecting across differences and the role of words in bringing a community together to envision a future for the St. Croix. At the end of the afternoon, a team of local improv actors will wrap up the day with a hilarious and thought-provoking original improv sketch. The goal is to create an event that will appeal to all attendees, whether citizen, scientist, policy maker or implementer.

Scandia farmers' breakfast

Scandia farmers’ breakfast

On a chilly morning in March, 30 local farmers gathered at the Scandia Community Center to meet staff from the Washington Conservation District and learn about new funding available for conservation projects on farms in the St. Croix Valley. During a hearty breakfast of bacon, eggs, and cinnamon rolls, District Manager Jay Riggs explained how elevated phosphorus levels in the St. Croix River are creating unhealthy conditions and what farmers can do to address this problem.

The Conservation District was established in 1942 in the wake of the dustbowl. Over the years, it has encouraged a variety of conservation farming practices, including using cover crops to hold the soil in place during the winter, building sediment basins that temporarily hold back runoff water and allow sediment to settle out, planting buffers of native or perennial plants along lakes and streams, creating grassed waterways in high-flow areas of farm fields, and planting trees to improve wildlife habitat and reduce wind erosion.

Five years ago, the Washington Conservation District received a grant from the St. Croix River Association to identify the “Top 50” locations in southern Washington County where conservation projects could most help to keep phosphorus and sediment out of the St. Croix River. Staff looked at potential projects identified in previous watershed plans and ravine inventories, in addition to conducting field assessments and site visits with land owners to identify new opportunities. Using modeling software, they estimated how much sediment and nutrients could be captured at each location and prepared a cost-benefit analysis of different structural and nonstructural practices that could be used. Then the district began reaching out to landowners.

During 2012 and 2013, the Washington Conservation District worked with five landowners in Afton and Denmark Twp. to install sediment basins on their properties in order to slow down rain runoff, reduce erosion, and filter out pollutants like sediment and phosphorus. A sediment basin is essentially a large, shallow bowl with a berm to hold back water from rain and melting snow, allowing time for suspended sediments to settle out. Pipes are built into the sides of the berms, allowing the water to flow through slowly so that it doesn’t cause erosion downhill or downstream. All five of the sediment basins were built upstream of eroding gullies that were previously sending large amounts of sediment and nutrients downstream to the St. Croix River. Together, these five projects will keep 163 pounds of phosphorus out of the river each year, which is the equivalent of 81,500 pounds of algae.

Now, the Conservation District has additional funding from the Minnesota Board of Water and Soil Resources, through a Legacy funded Clean Water Grant, to install additional conservation projects on farms near the St. Croix River in both southern and northern Washington County. By pairing state funds with local Watershed District funds, the Conservation District will be able to complete these projects at little to no cost to the farmers that own the land.

Though this particular grant is short-term, Riggs made it clear to the group in Scandia that the Washington Conservation District is interested in establishing long-term relationships with area farmers and landowners and in doing more than just one-time projects. No-till farming and cover crops are two additional conservation farming strategies that have been getting a lot of attention in the Midwest lately because they help to improve soil health so that farmers can achieve greater yields with less chemical fertilizers, thereby increasing profit margins. No-till and cover crops also result in less erosion because there is less bare soil during the year, which translates into less pollution for nearby lakes and rivers – a win-win situation for everyone.
