Located in Pottawattamie County, Iowa, the North Pigeon Cr Watershed Site M is a vital water resource managed by the local government for fire protection, stock, and small fish pond purposes. Constructed in 1996 by the USDA NRCS, this earth dam stands at a height of 17 feet and spans a length of 1160 feet, providing a storage capacity of 64 acre-feet. With a drainage area of 6.66 square miles, this structure plays a crucial role in flood risk reduction along the North Pigeon Creek.

Managed by the Iowa DNR, this site is regulated, permitted, inspected, and enforced to ensure its safety and effectiveness. The dam, with a hazard potential rated as low, has not been assessed for its condition but is considered to have moderate risk. Despite lacking an emergency action plan (EAP) and inundation maps, the North Pigeon Cr Watershed Site M meets regulatory guidelines while operating under the Omaha District of the US Army Corps of Engineers.

For water resource and climate enthusiasts, the North Pigeon Cr Watershed Site M presents an intriguing case study of local government involvement in managing water resources for multiple purposes. With its strategic location in Crescent, Iowa, and its role in flood risk reduction, this site exemplifies the importance of sustainable water management practices in enhancing community resilience to natural disasters.
