The Buffalo 9th Cavalry from nearby Fort Ringgold patrolled the rugged border country along this remote stretch of the Rio Grande in the late 19th and early 20th centuries. They dealt with rampant cattle rustling and banditry, protected isolated ranches, and navigated conflict on the often-tense international border. When you fish or boat the Falcon Reservoir, imagine the troopers who once rode its arid banks, working to bring peace to this volatile frontier. Falcon State Park continues to provide a cool refuge for both humans and wildlife; anglers from across the state visit to try their luck at one of the best freshwater fishing lakes in South Texas.
