Built in 1910, this gravity dam stands at 15 feet tall and spans 188 feet in length. With a normal storage capacity of 180 acre-feet and a maximum discharge of 3,670 cubic feet per second, Mix plays a vital role in harnessing the power of water to generate electricity.
Managed by the Federal Energy Regulatory Commission, Mix has a low hazard potential and is deemed to have a moderate risk level. The dam features an uncontrolled spillway with a width of 20 feet and is equipped with slide and vertical lift outlet gates for water flow regulation. While its condition assessment is currently not available, Mix undergoes inspections every three years to ensure its structural integrity and operational safety.
Water resource and climate enthusiasts will find Mix to be a fascinating example of historical hydroelectric infrastructure in Michigan. Its multi-arch design, soil foundation, and strategic location on the Grand River contribute to its role in renewable energy production. As efforts continue to monitor and maintain this important structure, Mix stands as a symbol of sustainable energy generation and the intersection of water resources and climate resilience.
