St Louis County: Aquatic Invasive Species Risk Assessment Tool

Screenshot of the story mapThe St. Louis County, MN Aquatic Invasive Species Risk Assessment Tool conveys the risk which lakes have in receiving new aquatic invasive species. We input spatial, environmental, and lakeshore development data into models to assess the risk of 1,139 lakes larger than 5 acres and assigned a unique basin identification number (i.e. these lakes exist in the MNDNR LakeFinder search tool). Additional information such as boater movement and lake habitat are provided to infer what AIS may pose the greatest risk of becoming established. Check it out here!

Use de-icing salt sparingy to protect Minnesota Waters

As the first snow of the season arrives, Minnesotans start thinking about clearing snow and ice from pavement - sometimes with salt.

It only takes 1 teaspoon of salt to permanently pollute five gallons of water. There's no feasible way to remove chloride once it gets into the water, and we are finding increasing amounts of chloride in waters around the state.

Salt will effectively remove snow and ice if it's scattered so the salt grains are about three inches apart.

SaltSmart Sticker

Additional tips for limiting salt use:

  • Shovel. The more snow and ice you remove manually, the less salt you’ll have to use and the more effective it can be.
  • 15oF and below is too cold for salt. Most salts stop working at this temperature. Use sand instead for traction, but remember that sand does not melt ice.
  • Slow down. Drive for the conditions and make sure to give plow drivers plenty of space to do their work. Consider purchasing winter (snow) tires.
  • Hire a certified Smart Salting contractor. Visit the MPCA's Smart Salting webpage for a list of winter maintenance professionals specifically trained in limiting salt use.
  • Watch a video. Produced by the Mississippi Watershed Management Organization, it offers tools for environmentally friendly snow and ice removal.
  • Promote smart salting. Work together with local government, businesses, schools, churches, and nonprofits to advocate for reducing salt use in your community.

Do you use felt-soled waders?

There is a growing concern felt-soled waders act as pathway of spread for aquatic invasive species. Trout streams and waters throughout the state are at risk.

Felt soles allow for a refuge and mode of transport for numerous invasive animals, plants and pathogens.

MN DNR has additional information on how you can prevent the spread of invasive species with your waders. Click here to learn more.

New Video on the Great Lakes Legacy Act Cost-Share Program

"A Seat at the Table: Great Lakes Legacy Act" is a new video that explains what it means to be a cost-share partner with the U.S. Environmental Protection Agency under the Great Lakes Legacy Act.  The video features interview with partners to describe the benefits and challenges of cost-share partnering, examples of in-kind services, and the flexibility of partnerships.

The GLLA is a component of the Great Lakes Restoration Initiative that addresses sediment remediation and habitat restoration in Great Lakes Areas of Concern.  Contaminated sediment—caused by toxic chemicals, heavy metals, oil and other pollutants—can be a serious problem for communities struggling to revitalize their waterfronts and boost their economies.

Since 2002, the EPA has partnered with 57 entities under the GLLA to study, design and execute sediment cleanups across the Great Lakes basin.  Over 4 million cubic yards of sediment have been remediated, removing threats to public health, creating vibrant environments for fish and wildlife, and giving coastal communities usable waterfronts.

What's a Vernal Pool?

Vernal pools are seasonal wetlands that provide essential habitat for wildlife, serving as the primary breeding ground for several species of amphibians and invertebrates, and important foraging habitat for many reptiles, mammals and birds.

Despite being an overlooked habitat type, vernal pools are abundant - it is estimated that more than 250,000 are located statewide!

Read more about what makes vernal pools so special, and how to manage them if you have them on your property.

MPCA Reports on St. Louis River Watershed Open for Public Review

The two reports open for public comment are the Total Maximum Daily Load (TMDL) study and the Watershed Restoration and Protection Strategies (WRAPS) report. The two are companion documents that quantify pollutant levels, identify pollution sources, and propose ways to return water quality to an acceptable level.

The WRAPS report summarizes information, tools and stakeholder input that can be used by local governments, landownders and others to decide on the best strategies and most effective places for those strategies to protect and restore water quality.

The draft reports are available on the MPCA’s St. Louis River Watershed webpage. The reports are also available at MPCA’s Duluth office at 525 Lake Avenue South. Comments should be submitted in writing by March 22, 2018, to Mike Kennedy, MPCA, 525 Lake Avenue South, Suite 400, Duluth, MN 55802, or by email to Questions about the reports can be directed to Kennedy at 218-302-6629 or 800-657-3864.

Blue Accounting Launches Major Effort to Protect Sources of Drinking Water in the Great Lakes Region

The Blue Accounting Initiative launched an effot to protect the waters that serve as the source of drinking water for 48 million people within the Great Lakes and St. Lawrence River basin.

The five main goals include:

  • Sources of drinking water are protected from nutrient impacts.
  • All public water supply systems are guided by up-to-date management strategies designed to protect source water.
  • Effective systems for spill prevention and response are accessible and in use by diverse stakeholders.
  • Actions are undertaken to improve our ability to monitor and decrease the number and volume of contaminants of emerging concern entering source water from municipal, industrial, commercial, and institutional sources.
  • Great Lakes states and provinces actively engage to build binational consensus on strategies for source water protection across the Great Lakes basin.

To put these goals into action, the coalition – Blue Accounting’s Source Water Initiative – is recruiting suppliers of water, and organizations working to protect local sources of drinking water, to showcase their unique local strategies and investments that support regional achievement of the five shared goals. These “Showcase Communities” will power the Blue Accounting process and support the Source Water Initiative in delivering a big picture view of progress toward reaching the five goals for source water protection.
