Ogemash, located in Becker County, Minnesota, is a federally-owned earth dam built in 1966 by the USF&W with a primary purpose classified as "Other." The dam, standing at a height of 8 feet and a length of 110 feet, has a storage capacity of 260 acre-feet and serves the Egg River watershed. Despite its low hazard potential, Ogemash plays a crucial role in managing water resources and mitigating flood risks in the region.
With a normal storage capacity of 72 acre-feet and a maximum discharge of 200 cubic feet per second, Ogemash provides essential water management functions for the surrounding area. While the dam's condition assessment is currently listed as "Not Rated," its inspection frequency is set at 8 years. Additionally, the dam lacks an Emergency Action Plan (EAP) and inundation maps, highlighting the need for improved risk management measures to ensure the safety and effectiveness of the structure.
As climate change continues to impact water resources and extreme weather events become more frequent, the role of dams like Ogemash in flood control and water supply management becomes increasingly vital. By staying abreast of maintenance needs, conducting regular inspections, and developing a comprehensive EAP, Ogemash can continue to fulfill its purpose of safeguarding the local community and environment from the potential risks associated with water management infrastructure.
