Texas' Deepest Lakes: Reservoirs Dominate the Depths

Texas' deepest lakes are all man-made reservoirs; natural lakes are shallow. The top five by maximum depth:

1. Lake Travis (Colorado River) – 210 ft (64 m) near Austin. Clear, deep, popular for scuba.
2. Lake Amistad (Rio Grande) – 160 ft (49 m) at dam. International reservoir, stratifies thermally.
3. Lake Buchanan (Colorado River) – 157 ft (48 m). First Highland Lake; flooded pecan orchards create structure.
4. Lake Texoma (Red River) – 130 ft (40 m) near Denison Dam. Striped bass mecca.
5. Lake Livingston (Trinity River) – 95 ft (29 m). Large, shallow relative to area; east Texas piney woods.

Context

Depths measured at conservation pool; flood pools add 10–30 ft. Natural lakes (Caddo, Green) rarely exceed 10–20 ft. Reservoir depth enables thermal stratification, critical for coldwater fisheries (trout stockings in Travis) and water quality management.
