Completed in 1983 by the US Army Corps of Engineers, this gravity dam stands at a height of 73 feet and spans 7730 feet in length. With a primary purpose of flood risk reduction, Copan Dam also serves for recreation and water supply, holding a maximum storage capacity of 338,000 acre-feet.
Managed by the US Army Corps of Engineers, Copan Dam presents a high hazard potential due to its location on the Little Caney River. The dam is equipped with a controlled spillway and has a very high risk assessment rating. To mitigate risks and protect the surrounding community, the Corps continuously monitors the dam's condition, conducts regular inspections, and collaborates with local emergency managers to develop emergency action plans and evacuation strategies.
Visitors to Copan Dam can appreciate its scenic beauty and recreational opportunities while being assured of the diligent risk management measures in place. As a vital resource for flood control and water supply in the region, Copan Dam exemplifies the complex balance between harnessing water resources and ensuring public safety in the face of potential hazards.
