Diamond Lake, located in Crow River, Minnesota, is a gravity dam completed in 1932 with a primary purpose of "Other." The dam stands at 7 feet tall with a length of 41 feet, providing a storage capacity of 44,908 acre-feet. Despite its low hazard potential, the dam is in poor condition as of its last inspection in 2015. The reservoir covers an area of 1,660 acres and has a drainage area of 14.4 square miles, with a maximum discharge of 185 cubic feet per second.

Managed by the Minnesota Department of Natural Resources, Diamond Lake is regulated, permitted, inspected, and enforced by state agencies. The dam is situated within the jurisdiction of the state and is subject to state regulatory oversight. Although the dam's condition is assessed as poor, its emergency action plan status and risk management measures are not specified in the data. The dam's location in Kandiyohi County adds to its significance as a critical water resource in the region, serving various purposes beyond flood control and water storage.

For water resource and climate enthusiasts, Diamond Lake offers a fascinating case study in dam infrastructure management and the intersection of environmental stewardship and public safety. The dam's historical significance, coupled with its current condition assessment and regulatory oversight, present an opportunity to delve into the complexities of balancing water resource management with infrastructure maintenance and risk mitigation. As a key feature in the local landscape, Diamond Lake serves as a focal point for discussions on sustainable water management practices, climate resilience, and the role of state agencies in safeguarding critical water resources for future generations.
