Biggest Lake in Texas: Sam Rayburn Reservoir (114,500 acres)

Sam Rayburn Reservoir is Texas's largest inland lake per the Texas Parks and Wildlife Department (TPWD). Below: 50 Texas lakes ranked by surface area.

The largest lake in Texas is Sam Rayburn Reservoir at 114,500 acres , in Jasper County (dam site); reservoir also spans Angelina, Nacogdoches, Sabine, San Augustine and Tyler counties County, according to the Texas Parks and Wildlife Department (TPWD). Toledo Bend is the largest body of water in Texas overall, but TPWD describes it as 'straddling the Texas-Louisiana state line' — roughly half its surface is in Louisiana, so Sam Rayburn is the largest lake entirely inside Texas.

Reading Texas's size profile

Texas's largest lake by surface area is Amistad Reservoir in Val Verde County, spanning 89,000 acres. Most of Texas's biggest waters are natural basins left by glaciers, with stable shorelines and deep main basins.

Surface area is a poor proxy for water quality on its own — a large lake can hold a clean, deep core and a nutrient-loaded bay at the same time. Each lake below links to its full page with nutrient readings, clarity, depth, and EPA impairment status. Area figures come from state DNR surveys and the USACE National Inventory of Dams; water-quality readings come from EPA and state monitoring data.

Frequently Asked Questions

What is the largest lake in Texas?

Sam Rayburn Reservoir, at 114,500 acres, in Jasper County (dam site); reservoir also spans Angelina, Nacogdoches, Sabine, San Augustine and Tyler counties County. Toledo Bend is the largest body of water in Texas overall, but TPWD describes it as 'straddling the Texas-Louisiana state line' — roughly half its surface is in Louisiana, so Sam Rayburn is the largest lake entirely inside Texas. Source: Texas Parks and Wildlife Department (TPWD), 2026-07-30.

How is lake surface area measured?

Surface area comes from state DNR lake surveys and, for reservoirs, US Army Corps of Engineers (USACE) National Inventory of Dams records. Area is reported in acres at normal pool level. Reservoirs rise and fall with management and drought, so their listed area is the long-term normal rather than a single-day reading.

Are Texas's largest lakes natural or reservoirs?

Of the top 50 Texas lakes by area, 21 sit on a dammed river (reservoirs) and 29 are natural basins. Glacial states (MN, WI, MI, NY) skew natural; plains and southern states (MO, IA, ND, OH) skew toward reservoirs built for water supply, flood control, and recreation.

Do larger lakes have better water quality?

Not reliably. Quality varies more within a big lake than between lakes — a large lake can have a clean, deep main basin and a murky, algae-prone bay fed by a tributary, so one reading can mask wide swings. Depth, watershed land use, and how fast the lake flushes matter far more than raw surface area.

How big is the typical Texas lake in this ranking?

Across the top 50 Texas lakes by surface area, the median is 12,283 acres (O. H. Ivie Reservoir). This list is biased toward the biggest waters; the typical Texas lake is far smaller.
