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.

    Col. Thomas J. Tickner, we were told the COE website would be down a “few days for repair”, then a few weeks, then after six weeks you needed another two weeks to fix a website that worked perfectly for years. Well, four weeks later, we still don’t have a working website that provides the stake holders of the lakes vital information to check water levels. Why? Ten weeks and counting to repair a working website Is it a newly design website? Are we going to get better information? What was posted on the old website was more than sufficient and very helpful in planning. I gather the priority on fixing the website wasn’t as high as stated. Why is it taking the COE over ten weeks and counting to repair a “vital” information website to the stake holders of the lakes? Please don’t tell us something is a “priority” when your actions show different. Ten weeks and count!

    • David: Thanks for commenting. I’m answering this on behalf of Col. Tickner. We understand, and share, your frustration. We want the site back up like you do. When the water management website went down we had to rebuild it from scratch. The site has been re-built and is currently going through additional scrubbing and security review from the U.S. Army Cyber Command. As a federal government agency, we must meet exceptionally high security standards to ensure the site meets the Defense Department’s web protocol and internet security requirements. These reviews also take time. Since we depend on authorizations from other organizations outside our district, we don’t have control over every step in the process. In the meantime, I hope our frequent posting of lake levels, generation schedules, and weekly declarations/projections on this blog and social media has somewhat mitigated the public need for information. We will notify the public as soon as the site becomes available. We’re hoping it is soon, too. Thanks for reading us! ~Russell Wicke
