Porcupine Dam

Porcupine Dam (National ID # UT00251) is a dam in East Canyon in Cache County, Utah, United States.

The earthen dam was constructed in 1964 by the Porcupine Reservoir Company, with a height of 165 ft and a length of 665 ft at its crest. It impounds the water of the East Fork of the Little Bear River, primarily for irrigation.

The reservoir it creates, Porcupine Reservoir, has a water surface of 190 acres, a shoreline of about 4.2 mi, and a maximum capacity of 12500 acre-feet, with an elevation of 5381 ft. The lake is popular for fishing, boating, and camping, although there are no recreational facilities. Only primitive camping is available at the reservoir; most areas for camping are located below the dam in the canyon.
