Falcon Reservoir, also known as Falcon International Reservoir or Falcon Lake, is a world-class fishing destination spanning 83,654 acres on the Texas-Mexico border. Created in 1954 on the Rio Grande River, this impressive waterbody extends through Zapata and Starr counties in South Texas. The reservoir experiences extreme water level fluctuations, often 40-50 feet or more below conservation pool elevation (301.2 ft msl) due to variable rainfall and water releases for downstream agricultural irrigation. These fluctuations significantly impact fishing conditions and habitat availability. Known for its trophy largemouth bass fishery, Falcon has established itself as one of the best bass fishing lakes in Texas, with tournament anglers routinely needing 5-6 pound average fish to be competitive. The reservoir features gradual sloping banks, with rock piles and standing timber providing structure during low water periods, while flooded terrestrial vegetation creates excellent cover when water levels are higher.
