Vega State Park, State park with mountain reservoir in Collbran, US

Vega State Park is a Colorado state park in the western part of the state, centered around a large reservoir sitting at roughly 8,000 feet (2,400 m) above sea level. Open mountain meadows and forested slopes surround the water on most sides, giving the park its open, high-country feel.

Vega Dam and Reservoir were built between 1957 and 1962 to irrigate the Plateau Valley, with water carried in by a canal from Park and Leon creeks and by Plateau Creek. Operation of the recreation facilities around the 925-acre lake passed to the state of Colorado in 1967, when Vega State Park was formally established in cooperation with the Bureau of Reclamation.

The park draws visitors throughout the year who boat, fish, and cross-country ski in winter months. These activities shape how the community uses and values this mountain reservoir.

Four campgrounds ring the reservoir: Early Settlers has 33 RV sites with hook-ups and a bathhouse, Aspen Grove 27 and Oak Point 39 with water pumps and rustic toilets, and Pioneer 10 tent sites plus five cabins sleeping six. The visitor center sits south of the dam. There is no swimming area in the lake.

The lake is actively stocked with rainbow trout, making it one of the few fishable lakes at this elevation in Colorado. Anglers visit year-round, including in winter when ice fishing is possible on the frozen surface.
