Barnett Reservoir decreasing release
Barnett Reservoir officials said Thursday reduced discharge through the dam to 37,000 cubic feet per second to begin slowing the release of water following a major rain event earlier in March.
The Pearl River Valley Water Supply District’s plan is to further decrease discharge later in the day, with more reductions over the weekend as inflows decrease at the 33,000-acre lake north of Jackson.
By lowering the lake ahead of the peak inflow, the PRVWSD succeeded in its plan to create storage needed to reduce ultimate crests downriver.
Inflows into the lake peaked Wednesday at around 45,900 cubic feet per second, according to the National Weather Service. The NWS said the Pearl River crested at Jackson at 33.35 feet Wednesday morning, over half a foot lower that originally predicted.
The NWS is forecasting a steady decrease in inflows into Barnett Reservoir through the weekend.
Barnett Reservoir stood at 297.85 feet above sea level at 8 a.m. Wednesday.
This will be the final press release related to this high-water event. Pearl River levels can be tracked online at these websites:
