Completed in 2004 by the USDA NRCS, this earth dam stands at 25 feet in height and spans 570 feet in length, with a storage capacity of 152 acre-feet. The dam serves the primary purpose of flood risk reduction along the Polecat river stream, with a low hazard potential and a moderate risk assessment rating.
Managed by the local government, West Fork Big Creek Dam P-35 has not been state-regulated or inspected since its completion. Despite its uncontrolled spillway and outlet gates, the dam's condition is currently not rated, and no Emergency Action Plan (EAP) has been prepared. With a risk management measure in place and a risk assessment rating of moderate, the dam continues to play a crucial role in mitigating flood risks in the area. Water resource and climate enthusiasts will find this structure an essential component in the overall flood risk reduction strategy for the region.
