Williams Dam, located in Lucas, Iowa, along the TR-White Breast Creek, was completed in 2010 with a primary purpose of providing fire protection and serving as a stock or small fish pond. Owned privately, this earth dam stands at a height of 34 feet and spans 560 feet in length, with a maximum storage capacity of 97 acre-feet. The dam is regulated by the Iowa Department of Natural Resources and undergoes regular inspections and enforcement to ensure its safety and compliance with state regulations.

With a low hazard potential and a condition assessment of "Not Rated," Williams Dam has not experienced any significant modifications since its completion. The dam's spillway width is 10 feet, and it has no outlet gates. Despite its relatively small surface area of 5.5 acres and drainage area of 0.34 square miles, the dam plays a crucial role in water resource management in the region. As a key feature along the TR-White Breast Creek, the dam contributes to the overall health and sustainability of the local ecosystem.

For water resource and climate enthusiasts, Williams Dam serves as a fascinating example of a privately owned earth dam designed by the USDA NRCS. Its construction and operation are vital for fire protection and supporting aquatic life in the area. With a focus on safety and regulatory compliance, the dam plays a crucial role in managing water resources and protecting the environment in Clarke County, Iowa.
