Abstract: Extremely heavy rainfall over the Timberlake basin in southwest Virginia on 23 June 1995 caused an earthen dam to fail and resulted in fatalities. The meteorological conditions are examined and reasons for the extraordinary amount of rainfall are postulated. Precipitation estimates from the Weather Surveillance Radar—1988, Doppler (WSR-88D) radar were used in hydraulic models (SMPDBK, DAMBRK, and HEC-1) to generate the failure peak flow and the time of failure.
