The 25 Biggest Lakes in Texas

• Ranked by surface area at conservation pool, taken from Texas Water Development Board hydrographic-survey reports. Each figure is read from the published survey rather than computed by us.
• TWDB figures can differ from familiar numbers because they are newer measurements: Lake Ray Hubbard's often-quoted 22,745 acres is a design-era estimate, and the 2015 resurvey measured 20,947.
• Conservation pool is the level a reservoir is operated to hold, so flood-pool areas are never used — they would let flood-control lakes leapfrog genuinely larger water supply lakes. Wright Patman's pool varies by season; its June-October recreation level is used.
• Shared border waters are excluded — Toledo Bend and Caddo (Louisiana), Falcon and Amistad (Mexico), and Texoma (Oklahoma) — because their full surface is not within Texas.
• A reservoir with no TWDB survey figure is left off rather than estimated. Satellite-derived outlines read 8-25% low for Texas reservoirs, so they are not used here.
• Public access inventories are not yet tracked for Texas here, so access is never shown or ranked.

Every number on this page comes from the same public agency records that power each lake's profile, and the list is recomputed as that data updates — it cannot silently go stale the way a hand-written top-10 does.
