CLARKS HILL, SC (WFXG) - This December, the Savannah River Basin received above-average rainfall at all three Corps of Engineers reservoirs. Excess rainfall filled the reservoirs past their "summer full pool" levels and into a portion of their flood storage space. A new record was also set for December rainfall in the Thurmond sub-basin.
We recorded 8.5 inches of rain in the Thurmond sub-basin this December. That's 220 percent of what's considered "normal" rainfall for the month. This is the wettest December on record for the Thurmond sub-basin, since we started recording data in 1948. The second wettest December on record for Thurmond was in 1953 with 8.35 inches.
This December we recorded 7.9 inches of rain in the Russell sub-basin (197 percent of normal) and 8 inches in the Hartwell sub-basin (156 percent of normal). In the last week of December the entire basin recorded 400 percent of normal rainfall, pushing reservoir levels above summer full-pool into flood storage.
