This Earth-type dam stands at a structural height of 47 feet and has a hydraulic height of 45 feet, serving a primary purpose that is classified as "Other." The dike spans a length of 19,266 feet and has a maximum storage capacity of 10,660 acre-feet, with a low hazard potential as assessed.
Situated along the Cape Fear River-Os, Motsu Disposal Dike plays a crucial role in water resource management in the region, with a maximum discharge capacity of 320 cubic feet per second. Although the dam has not been state regulated or permitted, it undergoes regular inspections to ensure its structural integrity and operational efficiency. Despite being labeled as "Not Rated" in terms of condition assessment, the dike's low hazard potential indicates a relatively low risk associated with its operation.
Managed by the Wilmington District of the US Army Corps of Engineers, Motsu Disposal Dike has not been assigned a Dam Safety Action Classification (DSAC) to date. The lack of an Emergency Action Plan (EAP) and limited risk assessment data suggest a need for further evaluation and planning to enhance the dam's overall safety and emergency preparedness measures. For water resource and climate enthusiasts, monitoring the ongoing management and potential updates to Motsu Disposal Dike will provide valuable insights into the sustainability and resilience of water infrastructure in the region.
