Falcon Lake Information

Falcon International Reservoir, also known at Falcon Lake, sits on the Rio Grande River with half of it in Texas, and half in Mexico. Its northern tip is 44 miles south of Laredo, Texas in Zapata and Starr Counties, and the county and city of Nueva Ciudad Guerrero, Tamaulipas, Mexico in the state of Nuevo Laredo, Mexico. Falcon Lake covers 78,300 acres with over 400 miles of shoreline and a maximum depth of 110 feet at the dam. Falcon Lake is owned, authorized, and operated by the United States and Mexico through the International Boundary and Water Commission. All lands on the United States (U.S.) side, except for Falcon State Park, are privately owned above 307 feet above sea level.

Americans are allowed on both sides of Falcon Lake without immigration or customs inspection if they do not land in Mexico or take aboard anything from Mexico. The United States side has nine public access areas. The dam runs along a two-lane highway connecting Farm Road 2098 and Mexican Highway 2 on its southern edge. Highway US 83 runs north to south on Falcon Lake’s eastern border. Zapata, Texas, is the only town on the U.S./Texas side close to Falcon Lake.

History Of Falcon Lake

The U.S. and Mexican governments approved the construction of Falcon Lake in the late 1940s for the purposes of water conservation, flood control, hydroelectric energy, and recreation. Construction began in 1951, and impoundment began in 1953. Presidents Dwight D. Eisenhower and Adolfo Ruiz Cortines dedicated Falcon International Reservoir October 19, 1953. Almost two miles of the dam is in the United States, and nearly three miles is in Mexico.

The U.S. and Mexico both operate three 14,750-horsepower turbines with each running three 10,500-kilowatt generators. The treaty allowed for the U.S.. to finance 58.6 percent and Mexico 41.4 percent. The conservation storage for both countries is based on the same percentages. The U.S. spent $35 million on construction costs and received $130 million in flood-control benefits by 1986. The original site of Zapata, Texas, and Guerrero, Mexico, lie under Falcon Lake. The original church in old Guerrero can still be seen from the Salado Arm of the lake.

The first European settled in Revilla, today’s Ciudad Guerrero, Mexico around 1750. The viceroy of New Spain commissioned Colonel José de Escandón to explore and colonize the frontier on the Rio Grande to the north with the promise of land grants from the Spanish government on both sides of the Rio Grande River. When the requirements for validation of the grants were met, settlement began in earnest around 1767.

Zapata, Texas, went through several names and began as a growing town on the Rio Grande River. Its first name was Habitación, and then changed to Carrizo, after an Indian tribe in the area that lived in cane huts. When Zapata county was carved out of Webb and Starr Counties, it became Bellville, Texas, after Governor Peter Hansborough Bell, who signed the bill authorizing Zapata County. Finally, in 1898, the town became Zapata, after local rancher Colonel Antonio Zapata. Camp Drum and Camp Harney were built in the 1850s to deal with border problems and Indian attacks in Zapata.

Fishing Falcon Lake

Falcon Lake presents interesting fishing conditions. You cannot fish below the dam because of sudden water surges based on irrigation needs and controlled by computer from Brownsville. The water fluctuation level is severe and usually 40 to 50 feet, or more. Americans are allowed on both sides without immigration or customs inspection if they do not land in Mexico or take aboard anything from Mexico. Launching at elevations below 250.50 is not available’.

On the Texas side of the lake, the daily bag limit for alligator gar is five fish, with no minimum length limit. All other fish are managed under statewide regulations. A Mexico fishing license is required for everyone in a boat. You do not need a Mexico boat permit. Mexico licenses can be purchased at tackle stores on the Texas side. For information on Mexico’s fishing regulations, visit the National Aquaculture and Fishing Commission (CONAPESCA) website.

The predominant species are largemouth bass and channel catfish. Other species include striped and white bass, bluegill, crappie, gar, and tilapia. Excessive netting from Mexican commercial fishermen along with frequent fish kills during summer low oxygen periods have significantly impacted the striped bass population.

Huge alligator gar in the triple digits and over 200 pounds have the attention of bow-fishermen. Look for crappie to be hanging around docks, bridge pilings, and brush along the deeper edges. There are nine public access areas on the Texas side of Falcon Lake, but no marinas. At low lake levels, rock piles and standing timber provide the majority of structure along with sparse hydrilla with aquatic vegetation.

Falcon Lake is huge on an international border. Fishing guide services can show you how to fish in international waters with no hassle. There are two countries involved in the operation of Falcon Lake which have different laws. Let a fishing guide show you the way and where the fish can be found on Falcon Lake.

Falcon State Park offers nine public access areas and a boat ramp with three 24-foot lanes at 262-foot elevation. Water levels at Falcon Lake significantly affect boat access. Launching at elevations below 250.50 is not available.

Falcon Lake is big enough for all types of boats like cabin cruisers, canoes & kayaks, fishing boats, houseboats, outboard motors, paddle boats, personal watercraft, pontoon boats, sailboats, ski boats, and sport boats. Bring your own gas. You do not need a Mexico boat permit.
