Choke Canyon Reservoir is a reservoir in South Texas, United States. The lake and the dam that creates it are owned by the United States Bureau of Reclamation and managed by the City of Corpus Christi.

Choke Canyon Reservoir is 4 miles (6 km) west of the town of Three Rivers and about 65 miles (105 km) south of the city of San Antonio. It impounds water from the Frio River shortly before the river's confluence with the Nueces River. The reservoir covers 25,670 acres (103.9 km²) in Live Oak and McMullen counties, and has a capacity of more than 695,000 acre-feet (857,000,000 m³) of water.

Choke Canyon Reservoir provides drinking water for the city of Corpus Christi. The reservoir also provides good fishing opportunities, especially for largemouth bass and catfish. Choke Canyon State Park, located in two places on the south shore of the lake, provides access to the lake and a number of other recreational activities.

Choke Canyon Reservoir has been stocked with species of fish intended to improve the utility of the reservoir for recreational fishing. Fish present in Choke Canyon Reservoir include alligator gar, white bass, white crappie, catfish, and largemouth bass, sunfish, and bluegill. Plant life in the lake includes American pondweed, coontail, water stargrass, rushes, cattail, and hydrilla.

It is also the westernmost range of the American Alligator.

The site hosted a rare bird, a Spotted Rail, in December 2020, attracting hundreds of birdwatchers.^[1] The record represents the 3rd record of the species for Texas, and the 4th for the United States.
