Completed in 1989, this earth-type dam stands at a hydraulic height of 60 feet and a structural height of 73 feet, with a length of 750 feet. It serves the primary purpose of water supply, with a storage capacity of 1050 acre-feet and a normal storage of 856 acre-feet.
Despite its importance, Indian Creek Dam poses a high hazard potential due to its poor condition assessment as of March 2018. With a high risk of failure, regular inspections are conducted every five years to ensure public safety. The dam's emergency action plan was last updated in September 2020, and measures are in place to manage potential risks. It is crucial for water resource and climate enthusiasts to monitor the condition and regulatory status of Indian Creek Dam to mitigate any potential hazards and ensure the sustainable management of water resources in the region.
