Located minutes north of Prescott, Willow Lake (formerly Willow Creek Reservoir) offers approximately 300-400 surface acres of water for paddling recreation. The lake allows electric motor boats, canoes, and kayaks, with a boat ramp available for launching. A $2 parking fee is required to access the lake.

Operating hours vary seasonally: 6 AM to 10 PM from Memorial Day through Labor Day, and 7 AM until sunset during the remainder of the year. Winter paddling can be challenging, with ice sometimes forming at put-in locations during cold snaps when temperatures drop to single digits. The Prescott Paddle Club regularly uses the lake for group paddles throughout the year when conditions permit.

The lake's size fluctuates throughout the year depending on rainfall, which affects available paddling areas. The shoreline features the distinctive Granite Dells rock formations, providing scenic views for paddlers. Wildlife viewing opportunities include various bird species, and the area serves as bear habitat.

Facilities include ramadas for picnicking, restrooms, and a fish cleaning station. The lake is stocked with several fish species including largemouth bass, crappie, catfish, bluegill, and sunfish. A hiking trail skirts the western shoreline, connecting to Watson Lake and Pioneer Park trails.

The lake's character blends recreational accessibility with natural beauty, though it can get busy during peak season. Located between Willow Creek Road and Highway 89, the main entrance and boat access is from the northwest side off Willow Lake Road.
