Falcon International Reservoir has been stocked with species of fish intended to improve the utility of the reservoir for recreational fishing. Fish present in the reservoir include largemouth bass, crappie, catfish, and channel catfish. The bass population is in decline, a factor which has reduced the number of fishermen and tourists coming to the lake. In 2012, Falcon Lake ranked first for bass in the United States; by 2014, the rank had dropped to number 12. Despite the threat of piracy, security on the lake has been enhanced to the point that State RepresentativeLyle Larson of San Antonio, a member of the House Committee on Culture, Recreation, and Tourism, declared Falcon Lake, "the safest park on the border." Alligator gar, large and heavy fish with a long lifespan, feed on the largemouth bass and can survive through droughts. In 2009, restrictions were placed on the harvest of alligator gar, but some area residents maintain that no regulations should be in place and that the gar must be considered as if they were rats and be removed from the lake. On the shores of Falcon Lake are Texas wild olive, Mexican oregano, hibiscus, mesquite thickets, huisache and prickly pear cactus. Greater roadrunners, collared peccaries, white-tailed deer, and black-tailed jackrabbits also exist within the park.
Recreation
Falcon State Park is located between Falcon Heights, Texas, and Nueva Ciudad Guerrero, Tamaulipas, and is the southern end of a International Falcon Reservoir. The park's main activities include camping, swimming, fishing, water skiing, and boating, with a self-guided nature trail. Bass fishing is particularly popular on the lake.
Piracy
In May 2010, Los Zetas pirates on the lake claiming to be Mexican Federal Police committed at least three armed robberies. The pirates boarded U.S. boats and demanded either weapons, drugs, or money. Fear of robbery has since dissuaded U.S. fishers from the lake. In June 2010, U.S. authorities also revealed a plot by Los Zetas to destroy the Falcon Dam. On September 30, 2010, David Hartley and his wife Tiffany, from McAllen, Texas, were in Mexican waters riding jet skis back from Mexico when they were allegedly chased by two boats containing about six gunmen. The Zapata County Sheriff said the woman escaped and reported that her husband was shot. He is missing and feared dead. On October 12, 2010, Commander Rolando Flores, the lead Mexican investigator for the David Hartley disappearance case, was beheaded by Mexican drug cartel members and sent in a suitcase to the Mexican military.
