Clean Water


Have you ever wondered where rain and snow melt go? Stormwater is one of the largest sources of pollution to our waters in the United States.

While a portion of the rain and snow melt can infiltrate into the soil, the remaining water flows over the surface (commonly referred to as runoff) and collects pollutants along the way such as sediment, trash, and oil.

Stormwater is not treated before it is discharged into surface waters.

In Howell, most of our stormwater goes to Thompson Lake, county drains, and other streams in the area. Polluted stormwater can negatively impact the uses of the surface water bodies for recreation including swimming, fishing, and boating.

Many new developments have best management practices (BMPs) in place to help reduce the amount of pollutants entering our surface waters. 

Some common examples include catch basins, rain gardens, and detention basins. There are also behavioral changes that we can make in our daily lives to help keep stormwater clean. To learn more about what you can do to reduce the pollutants entering Lake Thompson and surrounding surface waters, check out this presentation below.

This short presentation will walk through common BMPs and what maintenance they require along with ways to be mindful of stormwater pollution during property maintenance activities such as snow removal and lawn care.

Storm Water Best Practices


Anything that enters a storm drain goes to a local lake or river…

Storm water runoff eventually enters the storm system through a catch basin and is discharged directly into a lake, pond, stream, river or wetland. Some of these that are in your watershed area are, Thompson Lake, Bogue Creek, Marion-Genoa Drain, and the Shiawassee River.ou live on waterfront property? You do if there is a storm drain nearby! Storm drains carry runoff water to local lakes and rivers. Whatever washes off your yard and street can pollute these waters. That includes lawn fertilizer, grass clippings, pet waste, trees leaves and seeds, and car care soaps – these are all sources of phosphorus, the plant nutrient that turns lakes and rivers green with algae. Keep your runoff clean and keep our lakes and rivers clean!

Do you want to get involved in protecting Howell’s Watershed Area?

Besides following the Seven Simple Steps, there are several other things that Howell residents can do.
