Overview of Amistad Reservoir

Amistad Reservoir sits along the Rio Grande about 12 miles northwest of Del Rio, Texas. Created by the Amistad Dam in 1969, the reservoir forms the centerpiece of the Amistad National Recreation Area.

Lake Statistics

• Surface area: Approximately 64,900 acres

• Shoreline: Over 850 miles

• Maximum depth: About 217 feet

• Elevation: ~1,117 feet above sea level

• Water clarity: Usually clear to lightly stained

• Location: Val Verde County, Texas and Coahuila, Mexico

The lake is famous among bass anglers because its rocky canyon environment provides ideal habitat for both largemouth bass and smallmouth bass. According to Texas Parks and Wildlife, largemouth bass fishing at Amistad is considered excellent, with solid populations of smallmouth bass, catfish, and striped bass also present.

Rivers and Tributaries Feeding Amistad

Several rivers feed Amistad Reservoir, creating diverse habitats that attract bass throughout the year.

Major Tributaries

• Rio Grande River – Primary source of water flowing into the reservoir

• Devils River – One of the clearest rivers in Texas and a legendary smallmouth fishery

• Pecos River – Contributes nutrients and seasonal water flow

Each of these rivers brings different types of structure and forage into the lake. When water levels fluctuate, bass often move into these tributaries to take advantage of baitfish and warmer water.

The Rough Canyon Area

Rough Canyon lies on the northern section of Amistad Reservoir, roughly 20 miles north of Del Rio.

This section of the lake is known for:

• Steep canyon walls

• Long rocky points

• Deep structure close to shore

• Clear water

• Submerged rock ledges

The canyon environment provides excellent habitat for both largemouth and smallmouth bass, especially around:

• rocky drop-offs

• submerged brush

• hydrilla beds

• canyon ledges

• creek channels

Because deep water lies close to the shoreline, bass can move vertically through the water column with changing weather conditions.
