It has a storage capacity of 51 acre-feet and serves the purpose of irrigation for the surrounding area.

The dam features an uncontrolled spillway with a width of 30 feet and an outlet gate consisting of one valve. The last inspection was conducted in October 2018, with an inspection frequency of 5 years.
