The dam has a storage capacity of 70 acre-feet and a maximum discharge of 640 cubic feet per second, making it essential for water resource management in the area.
Despite its low hazard potential, the Hill James L dam is regulated, inspected, and enforced by the Oklahoma Water Resources Board. With a risk assessment rating of "Very High (1)" and a five-year inspection frequency, this structure plays a crucial role in mitigating flood risks and ensuring water security for the surrounding region. Although the condition assessment is currently "Not Rated," the dam's operational efficiency is maintained through a single valve outlet gate.

As an integral part of the local water infrastructure, this dam serves as a critical asset for climate and water resource enthusiasts interested in the intersection of dam safety, risk management, and environmental protection in Oklahoma.
