The U.S. Fish and Wildlife Services said today that releasing less water from Lake Lanier would not endanger several federally protected species living downstream, but the announcement is not the godsend for which state officials had hoped. Effective immediately, the U.S. Army Corps of Engineers can reduce flows out of Lake Lanier to 4,500 cubic feet per second, or CFS, until June 1, should drought conditions not improve. On average, the Corps has been releasing 5,000 CFS from Lake Lanier.
The Corps had originally hoped to reduce releases to 4,150 CFS, but FWS officials say they did not have enough time to research the effects such a move would have on all the species which rely on water flows. FWS studied how the change in releases would affect the Gulf sturgeon and three mussels species — the purple bankclimber, fat threeridge, and Chipola slabshell.
FWS officials say the reduced releases stand to affect the fat threeridge mussel the greatest. The sentinel species is at risk of losing 9 percent of its population. Should lesser releases be needed, FWS officials say they will work with the Corps.
The reduced releases will also benefit other downstream lakes, such as West Point, by allowing them to retain more water.
Here’s a snippet from release by FWS …
The modification provides for a pathway to increase composite storage – that is the amount of water stored at Lanier, West Point, and Walter F. George. If the Corps does not hold back some water now, and if extreme drought conditions continue, it is possible there may not be enough water in storage next summer to meet the needs of the users.
“We live here too, and fully understand what is at stake in the negotiation about how to allocate water,†Hamilton said. “As citizens throughout this basin, we are learning that choices have consequences and we cannot outgrow our carrying capacity, living beyond what our region’s natural resources can support.â€
“While fish and wildlife conservation is only a small part of this balancing act, we approach our role seriously,†Hamilton said. “It is our responsibility to ensure these indicator species, which help us assess the health of the system, are given the best chance possible to ultimately thrive. The better they do, the better we will do. Because if this drought has shown us anything, it has shown us we cannot thrive as a citizenry on an unhealthy river system. â€
