Stormwater Quality

What is Stormwater?

Stormwater runoff is precipitation that falls onto impervious surfaces such as roadways, driveways, parking lots and rooftops where it can accumulate pollutants, such as sediment, fertilizers, chemicals, oils, pet waste and trash. Instead of being absorbed into the ground, stormwater moves over these surfaces and makes its way into the drainage system and eventually into the Yampa River and its tributaries.
