Water and Sanitation District to provide recreation opportunities to the public at the Rueter-Hess Reservoir.
The vision is for the reservoir be “quiet”, “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.
