Big State, Only 1 Natural Lake!
The State of Texas has many beautiful lakes on which to boat, swim, and fish. However, only one of them - CADDO LAKE - is natural. Caddo Lake is found in East Texas and along (and into) the State of Louisiana.
All other lakes are either the work of the Army Corps of Engineers, or are just a narrowing in existing rivers (example: Sabine Lake on the Sabine River).
