Weekly Declaration: Corps to target lowest outflow at Hartwell since May

Today water managers with the U.S. Army Corps of Engineers released the weekly declaration and 10-week projection for the Savannah River reservoirs.

Our declaration targets lower outflows next week at the Hartwell Dam at a daily average rate of 3,120 cubic feet per second starting Monday Sept. 16. This is the lowest outflow rate we’ve targeted at the Hartwell Dam since May of this year.

At the Thurmond Dam, we will target a daily average outflow rate of 8,770 cfs starting Saturday Sept. 14. The Russell Dam will transition to an outflow rate of 7,600 cfs starting Sept. 16.

We continue to anticipate high amounts of total net inflow to the Thurmond sub-basin over the next week. In fact, for the remainder of this week and all of next week, we predict the total inflow to Thurmond will exceed the outflow from the Thurmond Dam (with the exception of Saturday and Sunday since the Russell and Hartwell Dams don’t generate on weekends).

As of this writing, all three reservoirs are above full pool. Hartwell is 660.55 feet per mean sea level (ft-msl); Russell is 476.37 ft-msl, and Thurmond is 330.33 ft-msl.

As always, the declaration is subject to adjustment if we receive high volumes of unexpected rainfall. If adjustments are made, we will post them in the comments section below.
