Falcon International Reservoir (also known as Falcon Lake or Dam) is located forty miles southeast of Laredo in Zapata County, on the Rio Grande. The dam and lake are managed jointly by governments of the United States and Mexico through the International Boundary and Water Commission (IBWC) for water conservation, flood control, hydroelectric energy, and recreation. The lake is named after María Rita de la Garza Falcón, for whom the town of Falcon (displaced by the creation of the reservoir) was named. The idea of a dam six miles east of the present site began about 1935, and the lake was approved by treaty at its present location in the late 1940s.

Falcon has long been regarded as one of the best largemouth bass lakes in the state. To win a bass tournament at Falcon, it often takes a 5-6 pound average/fish for your stringer. Channel catfish provide additional opportunities, with an occasional blue or flathead catfish.
