Cooper Creek Reservoir is a body of water behind an earthen dam across Cooper Creek in the Umpqua River basin of the U.S. state of Oregon. The reservoir is in Douglas County, about 2 miles (3 km) east of Sutherlin and about 11 miles (18 km) north of Roseburg.[1] The impoundment provides part of Sutherlin's drinking water.[4]

The reservoir supports populations of largemouth bass, panfish, and stocked rainbow trout.[5] The panfish and bass grow to large sizes, but mercury pollution from old mine tailings upstream makes eating them risky.[5] In 2001, the Oregon Department of Human Services issued a mercury-related health advisory for fish caught in the reservoir.[6] However, municipal water from the reservoir was deemed safe to drink, and the mercury posed no threat to recreational activities in the lake.[6] Mercury levels in the fish were not expected to diminish in the foreseeable future.[6]

Recreation

Cooper Creek Reservoir Park, managed by Douglas County, has two boat launches, a swimming area, and a dock.[7] It offers opportunities for fishing, waterskiing, and jet skiing. Amenities include a pavilion, a picnic area, and toilets.[7] The park is for day use only, and no camping is allowed.[5] A hiking trail circles the reservoir.[5]
