The dam was constructed in 1974 by the Perini Corporation as part of an expansive United States Army Corps of Engineers project for flood control, irrigation storage, and recreation.[1][2] The dam is 184 feet (56 m) tall, is 5,730 feet (1,750 m) long at its crest, and is the only major storage dam of the Fresno River.
The reservoir it creates, Hensley Lake, has a water surface of 2.5 square miles (6.5 km2), over 20 miles (32 km) of shoreline, and has a maximum storage capacity of 90,000 acre-feet (110,000,000 m3).[3] In 1978 the lake was opened to day-use recreation, including water skiing, fishing, swimming, horseback riding, mountain biking, and hiking.[4] The Hidden View Campground offers single and group camping year-round.
The lake is named for local settler and cattle rancher John Jackson Hensley.[5]
Eastman Lake, another Corps of Engineers lake, is located 15 miles (24 km) to the northwest.
