Recreation at the Rueter-Hess Reservoir

Castle Pines is part of the Rueter-Hess Recreation Authority to bring opportunities to the area

During the summer of 2015, Castle Pines City Council approved an Intergovernmental Agreement to join the Rueter-Hess Recreation Authority and partner with Parker, Castle Rock, Lone Tree, Douglas County and the Parker Water and Sanitation District to provide recreational opportunities to the public at the Rueter-Hess Reservoir. 


The vision is for the reservoir to be “quite”, “calm”, “tranquil” and “serene”. There will be non-motorized boats (kayaks, canoes, etc.). Fishing, camping, and hiking will also be available. However, since the reservoir is mainly used for drinking water, motorized boating and swimming will not be allowed.


In 2016, the Authority will develop a Recreation Master Plan for the area. To do so, the Authority will be soliciting public input regarding what the plan should include.

About the Rueter-Hess Reservoir

The Rueter-Hess Reservoir is located about 3-miles south-west of downtown Parker on Newlin Gulch. It has a capacity of 75,000 acre feet (AF) of water, encompasses 1,170 acres and has a dam that rises 185 feet above the bedrock. The primary purpose of the reservoir is to provide drinking water storage for the Parker Water and Sanitation District and it's regional partners, including Parker, Lone Tree and Castle Pines.


April 2016: An open house was held to showcase the Final Concept Map for the Reservoir. This map will help provide information for the Recreation Master Plan. 


Feb. 2016: Three concepts were shared at public open houses attended by 300 area residents. The concepts were also available online with a survey, which was completed by nearly 800 people. 


Jan. 8, 2016: The Recreation Authority closed its first online survey to solicit public input about what recreational activities residents would like to see at the reservoir. Nearly 4,000 responses were received. 


Oct. 13, 2015: Castle Pines City Council appointed Brad Meyering, Public Works Department, and City Councilmember Roger Addlesperger as the City of Castle Pines representatives to the Rueter-Hess Reservoir Recreation Authority (RHRRA) Board. The RHRRA Board is a partnership formed to develop a Recreation Master Plan and create new recreation opportunities for the area.
