Willow Lake – Prescott AZ

Description

Willow Creek dam and reservoir were constructed with Public Works Administration (PWA) funding in 1938-39.  Willow Lake is now the centerpiece of Willow Lake Park and there is a 6-mile trail around the lake.  It sits in an area called the Granite Dells, with impressive rock hills all around and prehistoric indigenous sites and petroglyphs.

Willow Creek Dam is constructed of concrete that tapers fro 6 feet thick at the base to 2 1/2 feet thick at the top and it is 85 feet high.  It created a reservoir of about 400 acres, with a storage capacity of 8,000 acre-feet. The project included a small diversion dam on Granite Creek and a diversion canal to Willow Creek.

Willow Creek reservoir was undoubtedly created for the Chino Valley Irrigation District, which had built the dam for Watson reservoir on Granite Creek in the early 20th century.  The city bought both reservoirs as the area urbanized in the late 20th century.
