Walker Dam, located in Montgomery County, Iowa, serves as a crucial structure for grade stabilization along a tributary to the East Nishnabotna River. Built in 2005 by the USDA NRCS, this private-owned earth dam stands at 30 feet high and stretches 450 feet in length, with a storage capacity of 32 acre-feet. Its primary purpose is to prevent erosion and protect the surrounding area, making it an essential component for fire protection, stock, or small fish pond creation.

Despite its low hazard potential, Walker Dam plays a significant role in managing the local water resources and enhancing environmental sustainability. With a normal storage capacity of 17 acre-feet and a maximum discharge rate of 130 cubic feet per second, the dam ensures efficient water retention and flow regulation. While its current condition assessment is not rated, the dam's presence is a testament to responsible water resource management and climate resilience in the region.

As a key part of the local infrastructure, Walker Dam contributes to the overall water management efforts in Iowa, particularly in the prevention of soil erosion and enhancing the ecological balance of the area. With its strategic location and design features, including a stone core and soil foundation, the dam stands as a testament to effective grade stabilization and water conservation practices. Its construction and operation reflect a commitment to sustainability and environmental protection, making it a valuable asset for water resource and climate enthusiasts alike.
