The dam is privately owned and regulated by the Iowa Department of Natural Resources, with state permitting, inspection, and enforcement in place. Situated on the TR-Chariton River, the earth dam stands at a height of 28 feet with a length of 528 feet, providing a storage capacity of 159 acre-feet and a surface area of 10.5 acres.

Despite being categorized as having a low hazard potential, Boswell Dam is considered to have a moderate risk level, with no official condition assessment rating available. The dam features an uncontrolled spillway and is designed to withstand various hydraulic pressures. The risk management measures, emergency action plan, and inundation maps for the dam are currently not publicly available. With its strategic location and purposeful design, Boswell Dam serves as a vital water resource structure in the region, contributing to both local water management and environmental conservation efforts.

For water resource and climate enthusiasts, Boswell Dam offers a unique opportunity to study the intersection of water infrastructure, environmental stewardship, and risk management. As a key component of the local water system, the dam's impact on the surrounding ecosystem and its ability to mitigate flooding risks are important areas for further exploration. With its relatively recent construction and ongoing state oversight, Boswell Dam represents a modern approach to water resource management in the region, highlighting the importance of sustainable infrastructure development in the face of changing climate patterns and water demands.
