Olmsted County Rd 10, located in Whalan, Minnesota, is a crucial structure regulated by the Minnesota Department of Natural Resources and Enforcement. Built in 1978 by the USDA NRCS, this Earth dam stands at a height of 37 feet and spans 440 feet across Lynch Creek. With a storage capacity of 114 acre-feet, this dam serves as a vital resource for flood control and water management in the region.

Despite its low hazard potential and satisfactory condition assessment, Olmsted County Rd 10 poses a very high risk due to its location and the potential impact of a failure. The dam's controlled spillway and uncontrolled outlet gates help mitigate this risk, but regular inspections every 8 years ensure its continued safety. Emergency action plans are in place, although further updates may be needed to meet current guidelines and ensure effective risk management measures.

As water resource and climate enthusiasts, it is essential to appreciate the importance of structures like Olmsted County Rd 10 in maintaining the delicate balance of water management and flood control in the region. By understanding the regulatory agencies involved, the dam's design and purpose, and its risk assessment, we can better appreciate and advocate for the continued maintenance and safety of this critical infrastructure.
