Water Quality IssueWater Quality Issue
Eutrophication caused by excessive nutrients (phosphorus and nitrogen) leads to many undesirable water quality symptoms.

Source of the ProblemSource of the Problem
Everybody within and upstream of the Watershed contribute in someway to the loading of nutrients to Barr Lake and Milton
Reservoir. Collectively, everyone can be a part of the solution.

• Planning Group started in Early 2002– FRICO, Metro, Thornton, CDPHE, Littleton, Englewood, Denver
• Phase 1 Non-Point Source State Grant 2004– Form Nonprofit Association
– Establish Directors, Committees, Annual Tour, Annual Meeting
– Build Water Quality Database (330,000 records from 360 stations)
• Phase 2 & 3 Non-Point Source State Grant 2005– Hire Watershed Coordinator
– Conduct Reservoir Assessments
– Write Watershed Plan
– Build Water Quality Modeling
– Develop pH Total Maximum Daily Load (TMDL)
