Mckean Dam in Nodaway, Iowa is a private dam completed in 2013 by the USDA NRCS for grade stabilization purposes. Located on a tributary to Kemp Creek, this earth dam stands at 29 feet high and stretches 419 feet in length, with a storage capacity of 30 acre-feet. The dam also serves recreational and water supply purposes, covering a surface area of 2.5 acres and draining a 0.07 square mile watershed.

Despite its low hazard potential, Mckean Dam has not been rated for its condition assessment. With no state regulation or inspection in place, the dam's maintenance and emergency preparedness measures remain unknown. However, the dam's strategic location in Adams County, Iowa, under the jurisdiction of the Kansas City District, signifies its importance in managing local water resources for both agricultural and recreational activities. For water resource and climate enthusiasts, Mckean Dam presents an intriguing case study of a privately-owned structure contributing to community development and environmental conservation efforts in the region.
