Recreation at Rueter-Hess Reservoir

Rueter-Hess Reservoir (RHR) is nestled in the sandstone-rimmed bluffs and Gambel Oak valleys of north eastern Douglas County. Abundant in history and rugged landscape, the reservoir resides on the property owned by Parker Water and Sanitation District (PWSD). It is an invaluable water resource to residents in Douglas County and people of the greater Front Range of Colorado. It is located on Hess Road, one mile east of I-25 at the Castle Pines Parkway, Exit 188, or three miles west of Parker Road.
