Twp Road 29 is a crucial earth dam located in Lyon County, Minnesota, designed for flood risk reduction along the Cottonwood River. Completed in 1999, this structure stands at a height of 22 feet and spans 500 feet in length, with a storage capacity of 3,235 acre-feet. Despite its low hazard potential, the dam is currently assessed to be in poor condition, highlighting the importance of regular inspections and maintenance to ensure its effectiveness in mitigating flood risks.

Managed by the local government, Twp Road 29 falls under the regulatory oversight of the Minnesota Department of Natural Resources - Division of Ecological and Water Resources. The dam's spillway type is uncontrolled, with a width of 6 feet, allowing for a maximum discharge of 573 cubic feet per second. While the dam is not equipped with outlet gates, its primary purpose remains focused on flood risk reduction, serving the surrounding community of Russell and contributing to the overall water resource management efforts in the region.

As water resource and climate enthusiasts, understanding the structural integrity and functionality of dams like Twp Road 29 is essential for ensuring the safety and resilience of communities in the face of changing weather patterns and increased flood risks. With a moderate risk assessment rating and a history of poor condition, stakeholders must prioritize proactive measures to address maintenance needs and enhance the dam's capacity to protect lives and property in the event of flooding events along the Cottonwood River.
