Twin Buttes Reservoir is a large, 9,080-acre impoundment located about 6 miles southwest of San Angelo where the Middle and South Concho Rivers converge. The reservoir, completed in 1963, offers multiple boat ramps for convenient water access across its expansive surface. With a maximum depth of 46 feet and numerous access points from surrounding roads, the site accommodates kayakers, canoeists, and motorboaters looking to explore a substantial inland water body in the Edwards Plateau region.
**Permits & Facilities:** Beginning September 1, 2016, visitors 17 and older need either a Limited Public Use permit ($12/year) or Annual Public Hunting permit ($48/year) to fish, hike, camp, or picnic in this area—permits are sold on a license-year schedule expiring August 31. Boat ramps are operated by San Angelo Parks & Recreation (325-277-8766). Primitive camping is available on shore areas adjacent to designated roads, with additional camping nearby at San Angelo State Park. The area's proximity to O.C. Fisher Lake and Lake Nasworthy provides options for exploring multiple water bodies in the region.
