Canyon Lake, Arizona - at Apache Trail.

Canyon Lake is one of four reservoirs that were formed by the damming of the Salt River in the U.S. state of Arizona.
The lake was formed by the Mormon Flat Dam, which was completed in 1925 after two years of construction. Canyon Lake, with a surface area of 950 acres (380 ha), is the third and smallest of four lakes created along the Salt River.
Two others, Apache Lake and Roosevelt Lake are upstream. The fourth, Saguaro Lake, is downstream.
