The dam has a hazard potential rated as high, with a fair condition assessment as of June 2018.

With a storage capacity of 1860 acre-feet and a drainage area of 1.16 square miles, Locke Dam plays a crucial role in managing water resources in the region. The dam's normal storage capacity is 1000 acre-feet, providing flood protection to the surrounding area.
