Two Buttes Reservoir is a State Wildlife Area in Baca County on the high plains of southeastern Colorado, roughly 30 miles south of Lamar. This remote reservoir sits in an arid landscape surrounded by prairie, rock formations, and the distinctive Two Buttes volcanic remnants. When water levels cooperate, the reservoir offers cliff jumping, swimming, fishing, and camping in a setting that reviewers describe as an oasis on the plains. When water levels drop — which has happened frequently in recent years — the reservoir can shrink to near-dry conditions.
Water levels at Two Buttes Reservoir fluctuate dramatically and are the single most important factor to check before visiting. Multiple reviewers report arriving to find the reservoir completely or nearly dried up, with water too shallow for swimming or boating. During a 2020 low-water period, the deepest point was only four feet, dead fish lined the shore, and thick knee-deep mud made wading miserable. When the reservoir is full, the experience is entirely different — visitors enjoy cliff jumping from rock formations along the shore, swimming in clean water, and fishing for panfish and bass.
The reservoir operates as a State Wildlife Area, and as of July 2020, anyone 18 or older needs a valid Colorado hunting or fishing license to access SWA properties. Camping is available in a primitive, dry-camping format with no hookups or developed sites. Vault toilets are on-site and reviewers describe them as clean and well-stocked. The area also attracts off-road enthusiasts, hikers, and wildlife watchers — pronghorn antelope, prairie dogs, and mule deer are common sightings.
The rock formations below the dam are worth seeing regardless of water levels, and the area known as the Black Hole draws curiosity from visitors. There is no cell service at the reservoir, so plan accordingly for navigation and emergencies. The location is remote with minimal facilities, making it best suited for self-sufficient visitors who bring their own water, supplies, and entertainment. Wind is a constant companion on the plains, and reviewers recommend preparing for gusty conditions. Despite the unpredictable water levels, Two Buttes Reservoir holds a loyal following among southeastern Colorado residents who grew up fishing and swimming here.
