Reservoir information

The primary purpose of Rueter-Hess Reservoir is to store and provide safe, clean drinking water, but there will be unique improvements to the site in the future to offer new recreational opportunities. The Town will be working along with the City of Lone Tree, City of Castle Pines, Town of Parker, Parker Water and Sanitation District and Douglas County, as part of the Rueter-Hess Recreation Authority, to determine additional outdoor activities for the reservoir.
