With a low hazard potential and satisfactory condition assessment as of September 2018, the dam has undergone modifications in 2002 to enhance its hydraulic and structural components. The dam's associated structures include other controlled outlet gates, and it has a spillway width of 78 feet to manage a maximum discharge of 783 cubic feet per second.
