Reported by: Trained Spotter

Heavy rain estimated at several inches (radar estimated at five inches) fell mainly in the Second and Third Creek basins in the southern portion of the county resulting in runoff over a roadway (Dry Fork Road). This runoff began during the evening of the 18th and continued into the morning of the 19th. This is only the second time that this has happened in the past twelve years (according to the Trained Spotter). The damaged section of road is about �� mile east of the Dry Fork Bridge. The force of the runoff carried away a portion of the south shoulder of the road; creating an abrupt drop off about 75 feet long and 3 feet deep.
