Rueter-Hess Reservoir

Rueter-Hess Reservoir is a municipal water supply reservoir in Douglas County near Parker, about 30 miles southeast of Denver. Unlike most Colorado reservoirs, Rueter-Hess is owned and operated by Parker Water and Sanitation District, which means it runs under a unique set of access rules and restrictions that visitors should understand before planning a trip. The reservoir opened for limited recreation and has become a surprisingly popular paddling destination for south metro Denver residents.

Paddleboarding and kayaking are the primary draws at Rueter-Hess Reservoir. The water is notably cleaner than many front range reservoirs, without the algae smell that plagues lakes closer to Denver. Motorized boats are not permitted, which keeps the water calm and makes it an ideal spot for stand-up paddleboarding without wake interference. Surf SUP Colorado operates on-site rentals for paddleboards and kayaks, and the staff receives consistently positive reviews for being helpful and knowledgeable. The reservoir sees light crowds even on weekends, giving paddlers plenty of open water and unobstructed views of the surrounding Douglas County landscape.

Fishing at Rueter-Hess requires a separate Parker Water fishing license in addition to your standard Colorado fishing license. The reservoir is catch-and-release only with barbless single-hook artificial lures required. Bank fishing access is limited, with roughly a third of the shoreline restricted, and submerged scrub oak and willows create frequent snags. Large carp in the 30-inch range have been spotted, but overall fishing results are mixed, with many anglers finding the restrictions and limited access frustrating. No wading, belly boats, or swimming are allowed.

Visitors must register and reserve online in advance, as there is no walk-up or pay-at-the-gate option. Entry costs $10 per vehicle. Parking is located at the top of a hill, requiring a carry down to the water for boat launching since there is no shoreline parking lot or formal boat ramp. Dogs are not allowed near the water, though they can be walked in the parking area and on some trails. Hiking trails loop around portions of the reservoir, including the Coyote Loop accessible from the Hess Road side, offering good views even for visitors who do not go on the water. Wind can pick up significantly on the open water, so checking conditions before kayaking or paddleboarding is advisable.
