One of three major reservoirs built to irrigate the parched Boise Valley over 100 years ago, the Arrowrock Reservoir stretches 18 miles up the canyon and spans 3,141 acres of water with a depth of 260 feet. Located at the confluence of the main channel and the south fork of the Boise River, the Arrowrock Reservoir is just a 30-minute drive from Boise and, due to a lack of visitors, is an ideal spot to enjoy nature at its best. Arrowrock Reservoir offers smooth and calm waters for water-based activities such as leisure and powerboating, wakeboarding, water-skiing, and sailing, is renowned for excellent fishing, and has a few campsites along the shoreline that offer camping, picnicking, and swimming.
