Rueter-Hess Reservoir, Protected water reservoir in Douglas County, Colorado.
Rueter-Hess Reservoir is a water storage facility in northeastern Douglas County, Colorado, set among sandstone cliffs and oak-covered valleys near the town of Parker. Beyond storing water, it is open to fishing, paddling, and hiking during parts of the year.
The Parker Water and Sanitation District launched the project in 1985, drawing on water rights tied to Cherry Creek to meet the growing demand of the surrounding area. Construction wrapped up in 2012, and the reservoir gradually opened to the public after that.
Guided programs and interpretive signs along the trails explain how water is collected and managed in this dry region. Reading the signs while walking gives visitors a clear sense of how water shapes life in this part of Colorado.
Reservations are required to take part in activities like fishing with artificial lures, paddling, or hiking, which run from April through October. Planning ahead is a good idea, as available spots can fill up quickly.
The reservoir actively protects the Denver Basin aquifer system through its daily operations, going well beyond simple water storage. This function is invisible to visitors on the trails, but it is a key reason why access is carefully managed.
