Abstract: A review was made of major reservoirs of the Corps of Engineers with regard to their experiences with induced seismicity. The Corps has 24 large reservoirs, i.e. those with dams 60.96 m (200 ft) in height or greater, and with volumes of 1233.5 x 10^6 m³ (1,000,000 acre-ft) or greater. There also are 10 dams that are 91.44 m (300 ft) high, or higher, but with reservoirs of less than 1233.5 x 10^6 m³. Thirteen reservoirs have been instrumented for monitoring microearthquakes. They range from large to small and are located in aseismic to highly seismic areas. Only one Corps reservoir, Clark Hill in Georgia-South Carolina, has experienced a felt earthquake, but the 21-year interval between impoundment and the occurrence of the earthquake is not typical of reservoir-induced earthquakes and a direct relationship appears improbable.
