The Travels of Lake Sturgeon
The MN and WI DNR partner on sturgeon research and management programs including a long running tagging study that is designed to learn more about the sturgeon population size and movements. Tagged fish have been caught numerous times by anglers and each have an interesting story.
Fossils, glaciers, and the water we drink
Poke along the trail at the Lilydale brickyards in St. Paul, and you’re likely to find fossilized remains of prehistoric sea creatures that lived 450 million years ago during the Ordovician period – bryozoans, crinoids, brachiopods, and trilobites. How did they end up here, more than 1000 miles from the nearest ocean?
Give me a home where the bees and butterflies roam
Recently, the Minnesota Legislature approved a third round of funding for the Lawns to Legumes Program, which was developed in 2019 to increase habitat for pollinators such as the federally endangered rusty-patched bumblebee. Minnesotans can apply for grants of up to $300 to support native planting projects, and there are larger grants for demonstration neighborhoods as well. Over the past two years, Lawns to Legumes grant recipients have created more than 800,000 square feet of pollinator habitat, including pocket plantings, pollinator lawns, and pollinator meadows / prairies.
Fifty-three Minnesota lakes and streams to be de-listed in 2022
Last week, the Minnesota Pollution Control Agency (MPCA) released its draft list of impaired waters for 2022. The list catalogs lakes, rivers and streams in our state that are impacted by a wide variety of pollutants and stressors. Some no longer support the fish and insect species that they used to. Others are prone to frequent algae blooms due to too much nutrients in the water. Still others have fish consumption advisories due to high levels of mercury, PCBs or PFOS. In total, 2904 water bodies in Minnesota are considered impaired.
PFAS contamination works its way to the St. Croix River
On Monday, November 8, the Minnesota Pollution Control Agency (MPCA) released a draft list of lakes, rivers and streams to be added to the state’s impaired waters list in 2022. Included are six water bodies in Washington County that have recently been found to have high levels of perfluorinated alkylated substances (PFAS), also known as the “forever chemical.” The affected waters include Tanners Lake (Oakdale), Eagle Point wetland and H.J. Brown Pond (Lake Elmo Park Reserve), Clear Lake (City of Forest Lake) and the St. Croix River/Lake St. Croix from Taylors Falls to Prescott.
Wetland in your yard?
When Marge Sagstetter and her husband Steve moved to Oakdale after 25 years in Lake Elmo, they took more than just their interior furnishings with them. Marge, a Master Gardener, had spent years lovingly cultivating and tending to gardens at her old home and, though she looked forward to a smaller, lower maintenance yard in Oakdale, she just had to bring a few flowers and ornamental grasses along with them when they moved.
Rich Fen, Poor Bog
You might not expect to find an ecological wonder in the middle of Woodbury, but Tamarack Nature Preserve is not only the southernmost tamarack wetland in Minnesota, but also, it turns out, both a rich fen and a poor bog …
Salt a growing problem for Minnesota’s water
University of Minnesota and others are currently researching new technologies that could reduce our need for salt, including novel applications of porous pavement, nano-technology and solar roads that prevent ice from adhering to pavement, salt-free water softeners, and chemical alternatives to road salt. Meanwhile, here are two ways that you can help to reduce salt use this year:
Street Sweepers to the Rescue
In the fall, many communities deploy street sweepers to clean-up city streets. Though the phrase “street sweeping” may conjure up images of a people with brooms, industriously sweeping our roadways, many modern street sweepers actually suck, like vacuums. Street suckers to the rescue?
On the forest and the trees
What if someone told you that you could skip raking your leaves this fall? It turns out that raking leaves off of your lawn can actually be counter-productive. “The leaves have organic matter in them,” explains Sam Bauer, Executive Director of the North Central Turfgrass Association. “You’re adding good organic matter to your soil when you’re not picking them up.” Instead of raking…
Virtual Project Tour
Take a virtual tour of some of our current partner-led efforts to protect and restore water resources in the Lower St. Croix Watershed. This tour showcases a variety of different types and scales of conservation practices, including: small-scale residential; large-scale agricultural; urban stormwater retrofits; and “capstone” projects that put water monitoring and pollution-reduction modeling into practice.
New project aims to take Lily Lake off the Impaired Waters List
Over the past twenty years, City of Stillwater, the MSCWMO, community volunteers, and local government partners have implemented dozens of lake-improvement projects to benefit Lily Lake. Projects have included stabilizing eroding gullies, redesigning the city-owned boat launch with porous pavers and native plants along the shoreline, installing raingardens in surrounding neighborhoods, retrofitting parking lots and stormwater ponds in commercial areas, and engaging community residents to adopt storm drains through the Adopt-a-Drain program.
Wildlife-Friendly Fall Gardens
There are several steps you can take to prep your yard and gardens for winter and continue to support pollinators, birds and other wildlife:
Protecting Mill Stream and the St. Croix River
The Mill Stream originates in William O’Brien State Park and flows downhill, across Hwy 95, and through the Brookside, before cascading down a waterfall to the St. Croix River.
Where the land is neither wet nor dry
We’ve scrambled over the hills, through the woods, and into a giant field of radish and turnip greens where Isanti County landowner Dave Medvecky is leading us deeper in to view a wetland restoration currently underway. It feels more or less like we’re walking through a giant bowl of salad.
Hard Fescue and SMART controllers Allow for Green Grass with Less Water
During a recent field day for cities and water professionals, University experts talked about some of the best strategies they’ve found for reducing the environmental impact of our traditional American lawn.
