National Dam Safety Program. Buffalo River Number 3 (Inventory Number VA 00911), James River Basin, Amherst County, State of Virginia. Phase I Inspection Report.
Abstract
Buffalo River No. 3 is a zoned, earthfill dam approximately 500 feet long and 60 feet high. The dam, located on Stonehouse Creek approximately 7 miles northwest of Amherst, Virgina, is used for flood control. Visual inspection and office analysis indicate no deficiencies requiring emergency attention. Using the Corps of Engineers' screening criteria for initial review of spillway adequacy,the Probable Maximum Flood (PMF) was selected as the spillway design flood (SDF). The Soil Conservation Service (SCS) freeboard hydrograph (which establishes top of dam) is essentially equal to the PMF hydrograph. The spillways will essentially pass the PMF without overtopping the dam, and are therefore considered adequate. The dam and appurtenant structures were found to be in generally good condition. No conditions indicating embankment instability were detected during the field inspection and office analyses.
