Lakes Hamilton and Catherine are a part of Project 271, a hydroelectric project licensed by the Federal Energy Regulatory Commission (FERC). Entergy operates these lakes and associated lands subject to the license issued and administered by FERC. FERC's license requires Entergy to manage use and occupancy of project lands and waters for public use and recreation.

This page was prepared by Entergy to provide the public with much-needed information about the project, its management, and what rights and responsibilities the public has to use of the project lands and water.

Entergy maintains and operates, but does not own the Toledo Bend Reservoir, on the Sabine River where it borders Texas and Louisiana. Toledo Bend, near the towns of Burkeville, Texas, and Many, La., is capable of generating 80 megawatts of power.
