Holloway Dam, also known as Richfield Storage Dam, is a gravity-type dam located on the Flint River in Genesee, Michigan. Completed in 1954, the dam serves primarily for recreational purposes and stands at a height of 38 feet with a hydraulic height of 27 feet. It has a maximum storage capacity of 29,900 acre-feet and a normal storage capacity of 15,350 acre-feet, covering a surface area of 1400 acres.
With a controlled spillway width of 240 feet and a maximum discharge rate of 36,200 cubic feet per second, Holloway Dam is equipped to handle high hazard potential. Despite its high risk assessment, the dam has been deemed to be in satisfactory condition, as per the last inspection conducted in August 2018. The dam is regulated and inspected by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE) to ensure its safety and compliance with state regulations.
Holloway Dam plays a crucial role in water resource management in the region and is a key feature for water and climate enthusiasts to explore and study. Its location on the Flint River provides valuable insights into the impact of dams on local ecosystems and water supply, making it a significant asset for research and conservation efforts in the area.
