It stretches 3200 feet in length and has a storage capacity of 42,200 acre-feet, serving a drainage area of 235 square miles.

The dam also serves multiple purposes, including flood risk reduction, hydroelectric power generation, irrigation, and recreational activities. Its controlled spillway, with a width of 35 feet, can handle a maximum discharge of 12,000 cubic feet per second. However, Viva Naughton has been classified as having a high hazard potential and a very high risk assessment rating, emphasizing the importance of regular inspections and emergency preparedness measures.
