Shryock Dam, also known as Benton Dam, is a private-owned structure located in Polk County, Iowa, along TR-Beaver Creek. Built in 1963 by the USDA NRCS, this earth-type dam stands at 30 feet high and is primarily used for fire protection and as a small fish pond. With a storage capacity of 34 acre-feet and a surface area of 2.6 acres, Shryock Dam plays a crucial role in managing water resources in the area.

Despite its satisfactory condition assessment as of April 2018, Shryock Dam poses a significant hazard potential, prompting the need for regular inspections and risk management measures. The dam is regulated by the Iowa Department of Natural Resources and is subject to state jurisdiction, permitting, inspection, and enforcement. In case of emergencies, it is important to have updated emergency action plans in place to ensure the safety of the surrounding community.

Located in Johnston, Iowa, Shryock Dam is a key infrastructure that not only serves practical purposes but also contributes to the local ecosystem and water management efforts. With its moderate risk assessment rating and the potential for significant impact in case of failure, ongoing monitoring and maintenance are essential to ensure the continued safety and functionality of this important water resource structure.
