10 actions you can take to improve Minnesota's lakes, rivers and streams

When it rains, the stormwater that runs off driveways, lawns, houses and parking lots can carry pollutants like oil, paint and chemicals down storm sewers and into nearby lakes, streams and rivers. By taking the following easy, no-cost or low-cost steps, you can have a big impact on reducing runoff and protecting our water resources and wildlife habitat.

Also see the Ten Things You Can Do to Improve Minnesota's Lakes, Rivers and Streams brochure (PDF).

1. Use your runoff

You can keep water in your yard and reduce runoff by directing downspouts onto your lawn or garden or into a rain barrel. Rainwater is free and naturally "soft," so it is ideal to use in watering your lawn or garden.

2. Don’t rake grass clippings and leaves into the street

Leave them on your lawn, use them for compost, or bag them up. Grass clippings and leaves left in the street end up in the storm sewer, where they are carried to nearby lakes and streams. Clippings and leaves contain phosphorus and other nutrients that feed algae and other aquatic plants. This can cause excess algae growth that can negatively impact other plants and wildlife and can be unsafe for pets.

3. Scoop the poop

Grab a bag when you grab the leash and pick up after your pets. Pet waste left on the ground can be washed into lakes and rivers with rainwater and runoff. Pet waste contains bacteria that can cause illness in humans and animals.

4. Use chemicals wisely

Read and follow the label instructions when using herbicides and pesticides. Use the minimum amount needed to control the problem. If you can, consider using alternative or natural remedies to control weeds and pests, or remove the problem by hand.

5. Fertilize smart

Sweep up any fertilizer that spills onto hard surfaces. Excess fertilizer washes away into nearby lakes or streams where it can feed algae, causing rapid growth known as algae blooms. Algae blooms stress fish and wildlife and make swimming and fishing unpleasant or impossible.

6. Keep a healthy lawn

A healthy, vigorous lawn needs less watering, fewer chemicals and less maintenance. Aerate your lawn periodically to loosen the soil. Seed bare patches to prevent erosion and soil loss. Mow at a higher setting. Grass mowed to a height of 2 ½ to 3 inches develops deeper, healthier roots and has a competitive advantage over weeds.

7. Plant a rain garden

Rain gardens are depressions planted with a diverse mix of native wildflowers and grasses designed to collect rainwater and allow it to soak into the soil. This will reduce the water running off your property into storm sewers. 

8. Replace turf with native plants

Swap some of your high-maintenance lawn for low-maintenance native ground cover, plants or grasses. Many native plants develop deeper root structures than turf grass, which reduces runoff by allowing for better water infiltration.

9. Reduce your footprint

Replace some pavement — such as a walk, patio or driveway — with pavers or pervious pavement. The porous surface will allow water to seep through.

10. Adopt a storm drain

Keep neighborhood storm drains free of leaves, seeds and grass clippings. Storm drains are directly connected to nearby water bodies. Water running into storm drains can carry with it anything dumped nearby including leaves, grass clippings, soil, oil, paint and chemicals.

Keeping storm drains clear will protect the water quality of nearby lakes, streams and rivers. Learn more about adopting a storm drain (DOC).

Aquatic invasive species prevention

Hennepin County is pursuing a variety of strategies to slow the spread of aquatic invasive species, including

  • Installing permanent boat-washing stations
  • Redesigning public accesses
  • Developing interactive educational displays
  • Training volunteers to be early detectors
  • Enhancing enforcement of AIS laws
  • Deploying rapid response protocols
  • Providing grants to cities, watersheds, park districts and lake associations

Learn more about these programs.

Taking care of trees

Trees and forests provide many benefits, including improving our air and water, making ourselves and our communities healthier, reducing the urban heat island effect, providing wildlife habitat, saving energy and increasing property values.

The tree canopy in Hennepin County faces a number of threats, including development, insects and diseases, climate extremes, and poor installation and maintenance.

Hennepin County has a variety of programs and resources available to help protect and enhance our tree canopy, including information about the emerald ash borer, tree waste disposal, and tree care volunteer programs. Learn more about trees and forestry.
