The BMW Association is collaboratively working to develop pH TMDLs for Barr Lake and Milton Reservoir. Read this page to learn more about what TMDLs are and how the BMW Association is developing them.
Barr Lake is sampled twice a month between March and October and monthly between November and February. The Barr Lake and Milton Reservoir Watershed Association coordinates all of the efforts to monitor, test, and improve the water quality in Barr Lake. Regular lake sampling started in 2002 and will continue into the future. It is important to closely monitor water quality to observe any major changes that would impact wildlife, park users, or downstream water users. Click below to see the latest water quality report.
