The Kass-Morgan Group Farm Pond, located in Lyon County, Minnesota, was completed in 1975 by the USDA NRCS with the primary purpose of flood risk reduction along the Cottonwood River. This private-owned earth dam structure stands at 26 feet high and spans 350 feet in length, providing a storage capacity of 89.4 acre-feet. With a significant hazard potential and a moderate risk assessment score of 3, the dam is under the regulatory oversight of the Minnesota Department of Natural Resources, ensuring regular inspections and enforcement to maintain its satisfactory condition.

Managed by the Natural Resources Conservation Service, the Kass-Morgan Group Farm Pond plays a crucial role in mitigating flood risks in the area by controlling the flow of the Cottonwood River. Despite its uncontrolled spillway and outlet gates, the dam has demonstrated its effectiveness in reducing the potential for inundation and protecting surrounding properties. The dam's satisfactory condition, last assessed in March 2017, highlights the commitment to maintaining its structural integrity and ensuring the safety of downstream communities.

As a vital component of the flood risk reduction infrastructure in Lyon County, the Kass-Morgan Group Farm Pond serves as a testament to the collaborative efforts between private landowners and government agencies to protect against the impacts of extreme weather events. With its strategic location and design, this earth dam structure exemplifies the importance of proactive water resource management in the face of a changing climate, providing a model for sustainable flood control practices in the region.
