Schwertley Dam, located in Harrison County, Iowa, was completed in 1959 by the USDA NRCS and serves multiple purposes including fire protection, stock, and a small fish pond. The earth dam stands at a height of 55 feet and stretches 552 feet in length, with a storage capacity of 303 acre-feet. Positioned along TR-Allen Creek, the dam's primary source agency is the Iowa Department of Natural Resources, which regulates, inspects, and enforces safety standards for the structure.

Despite being classified with a low hazard potential and moderate risk assessment, Schwertley Dam has not been rated for its condition assessment. The dam's emergency action plan, inundation maps, and risk management measures are also not readily available. However, the structure has not been modified since its completion and is owned and operated by a private entity. With its location near the Missouri River and its crucial role in water resource management, Schwertley Dam stands as a significant feature in Iowa's infrastructure landscape for water resource and climate enthusiasts to explore and study.
