National Dam Safety Program. Buffalo River Number 2 James River Basin, Amherst County, Virginia. Phase I. Inspection Report.
Abstract
Buffalo River No. 2 Dam is a zoned, earthfill dam approximately 800 feet long and 71 feet high. The dam, located on Thrashers Creek approximately 7.5 miles northwest of Amherst, Virginia, is used for flood control. Buffalo River No. 2 Dam is an 'intermediate' size - 'high' hazard structure as defined by the Recommended Guidelines for Safety Inspection of Dams. Visual inspection and office analyses 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.
