Morrow is a gravity dam located in Kalamazoo County, Michigan, built in 1941. It carries a High hazard potential classification and has a satisfactory condition assessment.
About Morrow
The primary purpose of Morrow is hydroelectric. The dam generates hydroelectric power by channeling water through turbines, converting the energy of flowing water into electricity. The dam is owned by Sts Hydropower Llc (private). It impounds the Kalamazoo River near Comstock.
The dam stands 26 feet tall and stretches 3,700 feet across, creates a reservoir covering 1,000 acres, has a maximum storage capacity of 6,000 acre-feet, and collects water from a drainage area of 991 square miles. Completed in 1941, the structure is well-established, with more than 75 years of service.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 06/28/2022.
