COBB-HIGHLAND RECREATION COMMISSION: Blackhawk Lake Study-Phase 1

A comprehensive assessment will be conducted of the physical, chemical, and biological condition of Blackhawk Lake and Otter Creek below the dam. A recreational use survey will also be conducted. Combined with the results of a Phase 2 watershed assessment and hydrologic and nutrient budget calculation, the data will be used to determine potential effects of various rates of hypolimnetic withdrawal on the water quality, fisheries, and aquatic life in Blackhawk Lake and Otter Creek and. develop specific goals and protection and management recommendations to support the multiple uses of the lake and downstream areas.
