The earth dam stands at a height of 8 feet and has a structural height of 10 feet, with a length of 6000 feet. It has a normal storage capacity of 130 acre-feet and a maximum storage of 1720 acre-feet, serving as a crucial water resource for the area.

Despite being classified as having a low hazard potential, the dam is rated as fair in condition assessment, with the last inspection conducted in September 2021. The risk assessment for Big Five Dam indicates a very high risk level, emphasizing the importance of ongoing monitoring and risk management measures. The dam's spillway, with a width of 35 feet, is of the controlled type, ensuring controlled water release during periods of high flow.

Owned privately, Big Five Dam is regulated by the Nevada Department of Water Resources and undergoes regular inspections and enforcement. With its historical significance and vital role in irrigation, the dam remains a key infrastructure for water resource management in the region, providing water for agricultural activities and contributing to the sustainability of the local ecosystem.
