The Chatfield Watershed Plan (Watershed Plan) addresses the beneficial uses– drinking water, recreational, aquatic life, and agriculture. Specific monitoring, studies, and projects within the Watershed can identify measures to protect water quality and maintain beneficial uses of these water uses for the future.

  • Chatfield Reservoir is an important drinking water supply
  • Chatfield State Park is one of the most visited in Colorado
  • Chatfield Reservoir and its Watershed are recognized for fishing

The Reservoir water quality does not consistently meet state regulations for water quality. The Chatfield Watershed Plan was developed to address this issue.
