Stormwater Information

Dayton’s stormwater management system is utilized to reduce the effects of pollution on the natural environment.  Stormwater is diverted to specific areas throughout the City in order to allow that stormwater to properly filter before entering back into the public water ways.

Stormwater Wet Pond Fact Sheet

This fact sheet focuses on stormwater wet ponds.  These are constructed ponds designated to capture stormwater runoff from impervious surfaces (e.g. streets, sidewalks, roofs)  Wet ponds help mitigate flooding and improve water quality in urban areas.  Please see link here for fact sheet.

Effects of Polluted Storm Water

  • Cloudy water deteriorates habitat for fish and plants
  • Nutrients promote algae growth, which crowds out other aquatic life
  • Toxic chemicals threaten the health of fish and aquatic life
  • Bacteria and parasites from waste make the lakes or bodies of water unsafe for wading and swimming

Adopt a Storm Drain Program

Sign-up to adopt a storm drain in their neighborhood and keep it clear of leaves, grass clippings, trash, and debris. This improves water quality. ​It takes approximately 15 minutes, twice a month.  ​“Natural” debris— grass clippings, leaves, and pet waste—become pollution when they hit our water. They feed algae, causing water to become green and soupy. This harms water quality, harms beneficial vegetation and wildlife, and harms recreation opportunities. 

Storm drains flow directly to local lakes, rivers, and wetlands, acting as a conduit for trash and organic pollutants. Adopt-a-Drain asks residents to adopt a storm drain in their neighborhood and keep it clear of leaves, trash, and other debris to reduce water pollution.

10 things you can do to protect Minnesota's lakes, rivers and streams

Is your watering under control?

How You Can Help!

Clean Up After Yourself!
This is the easiest thing you can do.  Any form of littering pollutes the environment.

Car Washing
Wash your car in your lawn with no-phosphorous soap. This keeps the soap out of the storm drains, and doubles up as watering your lawn.

Be sure to properly dispose of unused chemicals and old motor oil. These are bad for the environment and should be disposed of at a household hazardous waste collection site.

Create a Rainwater Garden
If you have a low spot on your property try planting water loving plants in that location. this will help filter unsafe chemicals from the ground water. More information of rainwater gardens can be found on the United States Environmental Protection Agency’s website.

Re-Direct Downspouts
Direct downspouts away from your house to prevent water problems in your basement. Also, direct them onto your lawn. This will prevent excess stormwater from overburdening the City’s stormwater management system. You may also direct the downspouts into rain barrels, which could then be used later around your yard and landscaping.
