Weekly Flow Release Plan: As a public service to the recreational users of Lakes Hamilton and Catherine and the Ouachita River below Remmel Dam, Entergy Hydro Operations periodically issues informational e-mails on lake and river matters. In addition to general information, these e-mails will also provide general guidance on when we plan to release water from the dams, which affects both the levels of the river below the dams and, to a lesser extent, the levels of the lakes. It can be useful in planning recreational outings for fishing and floating downstream. This e-mail is typically issued once each week or more often if conditions change (less often if conditions have not changed). Please note that water release information in this e-mail is only our current plan. Actual water releases may change without notice to meet various system demands or emergencies.

Lake and Shoreline Permitting Information: Entergy Hydro Operations will send emails to more quickly communicate matters regarding shoreline permitting and general lake information, similar in content to what is found in the Life on the Lakes newsletter. We will be able to quickly communicate information like lake drawdown information, emergent changes in lake levels due to threatening weather, changes in dock permitting requirements, warnings of heavy debris in the lakes, upcoming events on the lakes, etc. These emails could be especially useful to lakefront property owners, boaters, and other users of lakes Hamilton or Catherine. These emails will be issued approximately once a month, or as needed to communicate emergent information.

Special Release Request Process

Entergy has agreed to provide up to four days per year of special full–generation releases from Remmel Dam for swift-water rescue training and other educational and organization type events. These releases can be up to six hours each. To allocate these days among the various groups, who might request one of these special releases, Entergy has developed the following process. Failure to follow this process could result in the denial of your request.

  • Any individual or group who desires to request a special release from Entergy must register before April 1st of the current year
    • Failure to register by the deadline could result in your request not being considered
  • Special Requests must be emailed to Entergy Shoreline Management at shoreline@entergy.com
    • All correspondence will occur by email
  • Entergy will review all requests, and if necessary, ask those requesting special releases on the same day to find common ground in an attempt to achieve consensus
  • Entergy will make the final decision approving or denying the special request based upon the numerous factors, including:
    • Past History of Special Release Requests with accompanied successful events and satisfactory working relationship with Entergy;
    • The past demonstrated stewardship of the river;
    • Number of people that the event will serve;
    • Demonstrated potential for the requested Special Release to provide the most benefit for the most people
    • Type of organization and purpose of the event: Public service, commercial, social, etc. (i.e., who will benefit from the release)
  • If Entergy’s normal operations for the requested date provides the requested flow in the manner requested (in other words, we were releasing anyway) then the special release request will not be counted against the four days of annual allocation
  • Once the four agreed-to days are either used or allocated, Entergy may consider additional requests, but may deny any or all of them
