Flow Release Information as of 10-27-2014
Drawdown begins this Saturday, November 1
We will continue operating in a minimum flow release mode for the remainder of this week of just above 200 CFS from Remmel Dam. Beginning on Saturday, November 1, we will start releasing approximately 3,600 CFS from 1 pm to 8 pm to lower both lakes Hamilton and Catherine three feet to their wintertime drawdown levels. The water released by the dams will be used to generate emission-free, low-cost hydroelectric power. Lake levels will be reduced about 4 inches per day and the drawdown will be complete on both lakes by Sun. Nov. 9.
The lakes will return to their summertime levels in mid-March of 2015.
In addition to facilitating shoreline facility maintenance and inspection, the annual drawdown is part of a plan to help control nuisance aquatic vegetation. Entergy Arkansas coordinates the annual winter drawdown with the Arkansas Game and Fish Commission. Fisheries, vegetation, facility management and downstream water needs are the key factors considered in deciding the drawdown’s depth and timing.
Safety during the Drawdown
Boaters should use caution while on the lakes during the drawdown period because there will be more shallow areas and winter rains can increase the amount of debris washed into the lakes. Owners of boats and floating docks should also take precautions to ensure they are able to adjust to the drawdown. Failure to do so may cause damage to them. Some docks will be able to rest on the lakebed with little or no problem. If the shoreline is steep or rocky in a particular area, dock owners may need to temporarily move docks to deeper water. If relocating a dock, be sure it does not restrict navigation or become a boating hazard.
Important Shoreline Permitting Information
Entergy Arkansas will not require a permit for the temporary relocation of docks due to the drawdown, but the dock must be returned to its permitted location once the lake returns to its summertime level in March. Entergy Arkansas also recommends using a licensed electrician to make any alterations to wiring in conjunction with the drawdown.
The deadline for filing shoreline facility applications is November 30 for construction activities to be worked during the winter drawdown. Applications received after the deadline will be set aside to process after the refill unless the applicant is willing to pay an expedited processing fee of twice the normal fee to have it evaluated before the end of the drawdown. So a typical seawall permit that costs $550 now will be $1,100 to expedite. Permit applications received after January 31 will not be considered for this expedited process.
