After receiving above-average rainfall in April, the Savannah River reservoirs recorded normal rainfall levels for the month of May. The Hartwell sub-basin received 98.6 percent of normal rainfall for the month, and Thurmond received 101.7 percent of normal.
Nearly half of the month’s rainfall occurred in a single rain event on May 15—dumping 2.7 inches at both Hartwell and Russell and 2.3 inches at Thurmond.
Lake levels remained fairly constant throughout the month. Hartwell Lake remained within 1 foot above full summer pool (660 feet above mean sea level) and Thurmond Lake remained within 1 foot below full pool (330 ft-msl). We continue to target an elevation of about a half foot below full pool at Thurmond while workers perform gate repairs at the dam.
