Jones Dam, located in Taylor County, Iowa, was completed in 2002 and serves as a crucial resource for fish and wildlife conservation, grade stabilization, and water supply. The dam, designed by NRCS, is an earth-type structure with a height of 25 feet and a length of 330 feet, providing a storage capacity of 44 acre-feet. It is situated on a tributary to the East Fork river and falls under the regulatory jurisdiction of the Iowa Department of Natural Resources.

Despite being classified as having a low hazard potential, Jones Dam is subject to regular state inspections, permitting, and enforcement to ensure its continued safety and effectiveness. The spillway, with a width of 14 feet, is uncontrolled, allowing for a maximum discharge of 80 cubic feet per second. The risk assessment for the dam is moderate, with a rating of 3, highlighting the importance of ongoing risk management measures.

In the event of an emergency, the dam does not currently have an Emergency Action Plan (EAP) in place, and the condition assessment is listed as "Not Rated." With its location in a rural area, Jones Dam plays a vital role in supporting the local ecosystem and maintaining water resources for the surrounding community.
