Barr Lake And Milton Reservoir Watershed Association

The Barr Lake and Milton Reservoir Watershed Association works to keep the water clean in Barr Lake and Milton Reservoir on Colorado's Front Range, a watershed draining much of the Denver metro area. It conducts water quality monitoring and modeling, runs a phosphorus-free-fertilizer outreach campaign to curb algal blooms, and has removed more than 35 tons of invasive common carp from Barr Lake.
