Quail Creek reservoir was completed in 1985 to provide irrigation and culinary water to the St. George area. Most of the water in the reservoir does not come from Quail Creek, but is diverted from the Virgin River and transported through a buried pipeline.
Two dams form the reservoir. The main dam is an earth-fill embankment dam. The south dam is a roller compacted concrete dam, constructed to replace the original earth- fill dam that failed in the early hours of New Year's Day 1989.
The maximum depth of Quail Creek can reach 120 feet, so it is cold enough to sustain the stocked rainbow trout, bullhead catfish, and crappie. Largemouth bass, which are also stocked, and bluegill thrive in the warmer, upper layers of the reservoir.
Opened to the public as a state park in 1986.
