Zellmer Subwtrshd #M 106+26, located in Woodbury County, Iowa, is a dam built in 1964 by the USDA NRCS for fire protection, stock, and small fish pond purposes. This earth dam stands at a height of 39 feet and stretches 542 feet in length, with a storage capacity of 149 acre-feet. Despite its relatively low hazard potential and moderate risk assessment rating, the dam's condition remains unrated, with no recent inspection or emergency action plan in place.

The dam, situated along the TR-West Fork Little Sioux River, serves a vital role in flood risk reduction within the area, covering a drainage area of 2.08 square miles. While currently lacking in certain regulatory and maintenance aspects, such as spillway controls and inspection records, the Zellmer Subwtrshd #M 106+26 dam underscores the importance of proper management and upkeep of water resources in ensuring community safety and environmental sustainability. Climate enthusiasts and water resource advocates alike may find interest in monitoring the developments and improvements of this local government-owned structure to safeguard against potential risks and enhance its overall resilience in the face of changing weather patterns and hydrological conditions.
