This earth dam, with a buttress core type, serves primarily for recreational purposes and holds a maximum storage capacity of 74 acre-feet. Situated on the Palmetto Hollow stream, the dam has a normal storage capacity of 30 acre-feet, covering a surface area of 4.3 acres and draining an area of 1.12 square miles.
Managed by a private owner, the dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections to ensure its structural integrity. In 1991, the dam underwent structural modifications to enhance its safety and efficiency. With a fair condition assessment as of February 2016, the dam's risk assessment is moderate, calling for appropriate risk management measures to be in place. Despite its uncontrolled spillway type, the dam poses a moderate hazard potential and a maximum discharge capacity of 2 cubic feet per second.
Although the dam has not been associated with any federal agencies or funding, its role in providing recreational opportunities and its importance in managing water resources in the region make it a key structure for water resource and climate enthusiasts to monitor and appreciate. With its picturesque location in the scenic Nameless Valley Ranch, this dam stands as a testament to human engineering and environmental stewardship in balancing the needs of water storage and recreational activities.
