Spring 2016 Lake Refill Dates Announced

The annual refill of both Lake Hamilton and Lake Catherine will begin on March 5 and be completed by March 15 this year. Lake levels will be raised about six inches per day. Both lakes are drawn down each year typically either three feet or five feet on an alternating basis. The 2015/2016 drawdown was for five feet so we are anticipating a three foot drawdown for the winter of 2016/2017. We work with the Arkansas Game & Fish Commission to monitor the vegetation each year sometime in August to set an appropriate draw down amount for each winter. Check back here in September for further information on our next drawdown.

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.
