Rainbow Lake Dam
April 30, 2024
Rainbow Lake Dam, located in Maple Rapids, Michigan, is a private dam constructed in 1962 primarily for recreational purposes. With a height of 46 feet and a length of 1000 feet, this earth dam stores up to 5400 acre-feet of water from the Pine Creek, covering a surface area of 238 acres. The dam is regulated by the Michigan DEGLE and undergoes regular inspections to ensure its structural integrity and safety.
Despite being classified as having a significant hazard potential, Rainbow Lake Dam has been assessed as satisfactory in condition, with the last inspection conducted in May 2019. The dam's spillway, with a controlled design and a width of 40 feet, helps manage water discharge during peak flow periods. In case of emergencies, the dam's emergency action plan was last revised in 1998, indicating the importance of preparedness and risk management at this site.
Overall, Rainbow Lake Dam presents a unique opportunity for water resource and climate enthusiasts to explore the intersection of human-made infrastructure and natural water systems. As a recreational dam in a picturesque setting, it serves as a reminder of the delicate balance between harnessing water resources for human use and ensuring the safety and sustainability of these structures for future generations.
