In the future, design and construction of a modern campground with both tent and RV camping is planned. The campground is slated to have full hook ups, showers, flush toilets and a dump station.

Dog Off Leash Area

A dog off leash area is located on the south side of the reservoir. Dogs are allowed off leash and may swim in this designated area. Dogs must be leashed in all other areas of the park.

Fishing

Union Reservoir is fast becoming one of Colorado's finest Walleye fisheries. Walleye 17 to 24 inches are common. In recent years, Union Reservoir has become the hotspot for fly fishermen who enjoy the thrill of catching the hard fighting Carp. In addition, a healthy population of Trout, Crappie, Catfish, Bass, Sunfish, Wiper and Tiger Muskie provide a quality fishing experience. Fishing is available along the majority of the shoreline or from a boat. Colorado fishing regulations are enforced and a fishing license is required. A fish cleaning station and handicapped accessible fishing pier are provided for your convenience.
