Today's Media Release from PRVWSD on Discharge

13 March 2016
Barnett Reservoir maintains discharge

Barnett Reservoir officials said Sunday morning they would maintain the current discharge rate of 40,000 cubic feet per second at the dam, preparing for a Wednesday crest of the Pearl River forecasted by the National Weather Service.

In a conference call Sunday morning that included the National Weather Service, the Lower Mississippi River Forecast Center in Slidell, the U.S. Army Corps of Engineers and the City of Jackson, the Pearl River Valley Water Supply District it was agreed to maintain the discharge until the reservoir starts falling. The lake was at 298.03 feet above sea level Sunday morning.

Current inflow into the reservoir is 38,000 cubic feet per second and the National Weather Service said a peak of 44,200 cubic feet per second is expected on Wednesday.

Once it confirms the lake level is dropping, the PRVWSD said some adjustments in discharge could be made. The plan is to lower the lake before the peak inflow to create storage capacity and reduce the ultimate river crests at downriver locations.

The National Weather Service is still predicting the Pearl River to crest at 34 feet in Jackson on Monday, which will cause some street flooding. The forecast is based on inflows, past rainfall and rainfall predictions for the next 48 hours. River levels can be tracked online at these websites:
