Figure 1. Map of warm-water reaches of the Colorado River upstream of the confluence with the
Green River (lower black line). Black lines at the upper end of the 15-mile reach and 2.2 miles up
the Gunnison River mark the locations of diversion dams that block upstream movement of fish.
A recently constructed fish ladder at the Gunnison River barrier should allow future access of
Colorado River endangered fish to upstream reaches of the Gunnison River. Black lines also
mark the extent of Westwater Canyon, a transition zone between habitat for juvenile (lower
reach) and adult (upper reach) Colorado squawfish.
