Goddard Dam, located in Villisca, Iowa, is a privately owned earth dam designed by USDA NRCS and completed in 2005 for grade stabilization purposes along a tributary to the West Nodaway River. The dam stands at 25 feet high, with a length of 450 feet, and has a storage capacity of 28 acre-feet. Its primary purpose is to stabilize the surrounding area and prevent erosion, with a low hazard potential and a condition assessment that is currently not rated.

The dam, situated in Montgomery County, Iowa, has a normal storage capacity of 17 acre-feet and a maximum discharge rate of 129 cubic feet per second. It covers a surface area of 3 acres and serves a drainage area of 0.05 square miles. While the dam does not have outlet gates or a spillway type specified, it is inspected periodically for its structural integrity and maintenance. The surrounding community benefits from the dam's function in regulating water flow and reducing the risk of flooding in the area.
