The dam, with a height of 35 feet and a length of 575 feet, creates a reservoir with a storage capacity of 215 acre-feet. Situated on an unnamed tributary of Crooked Creek, the dam has a spillway width of 24 feet and a maximum discharge capacity of 834 cubic feet per second, making it an essential component for flood control in the area.
Despite being classified as having a "High" hazard potential, the dam is currently in fair condition as of the last assessment in 2004. Regular inspections are conducted every two years to ensure the structural integrity and safety of the dam. The risk assessment for Lake Holly Dam indicates a moderate risk level, with appropriate risk management measures in place to mitigate potential hazards. While the dam does not have outlet gates, its uncontrolled spillway design allows for the controlled release of excess water during periods of high inflow, safeguarding downstream areas from flooding.
Lake Holly Dam serves as a vital recreational and flood control asset in the region, providing not only water storage for various activities but also protection against potential flooding events. With its strategic location and design features, the dam continues to play a crucial role in water resource management and climate resilience efforts in Spencer, Indiana.
