Canyon Lake is one of four reservoirs that were formed by the damming of the Salt River in the U.S. state of Arizona as part of the Salt River Project.

It was formed by the Mormon Flat Dam, which was completed in 1925 after two years of construction.

Canyon Lake lies approximately 15 miles (24 km) up the Apache Trail from Apache Junction, Arizona and 51 miles (82 km) east of Phoenix.

Recreation amenities include hiking trails, camping, and boating, all managed by the United States Forest Service.

Canyon Lake is a popular stop along the Apache Trail (Arizona State Route 88) from Apache Junction, Arizona, passing Tortilla Flat, Arizona, before reaching Apache Lake and Roosevelt Lake behind Theodore Roosevelt Dam.
