How does rain and stormwater runoff affect Lake Champlain?

Excess water from rain or snowmelt flows over surfaces like driveways, sidewalks, and streets picks up pollutants such as oil and grease, chemicals, nutrients, metals and bacteria, flowing into stormwater systems or directly to the lake, streams, rivers or wetlands.

Interests

Rethink Runoff helps communities consider the impact of stormwater runoff in Chittenden County. Excess water from rain or snowmelt flows over surfaces like driveways, sidewalks, and streets picks up pollutants such as oil and grease, chemicals, nutrients, metals and bacteria, flowing into stormwater systems or directly to the lake, streams, rivers or wetlands.

Anything that enters the stormwater system is discharged untreated into the waterways we use for swimming, fishing and providing drinking water.

Ms. Drop's Monthly Tip

Join up with the Stream Team. We’re always looking for people to help to stream monitoring and other activities throughout the year.

Explore our Basin

The Lake Champlain Basin holds a number of watersheds, area of land where all water travels to the lowest point – a river, stream or lake. This is often how stormwater runoff ends up in Lake Champlain. Learn more about how your efforts can help keep sediment, debris and chemicals out of local streams and rivers.
