"Glen Canyon Dam's reservoir — 186 miles long, threaded through red-rock canyons that emerge as the water level drops. Iconic Antelope Canyon and Rainbow Bridge are within boat range. Like Mead, has dropped dramatically due to drought, exposing landscapes drowned for 60+ years."

Seasonal pattern

When does Lake Powell warm up?

Lake Powell is deep (max depth 583ft) and carries significant thermal inertia, so it warms slowly — surface temperatures typically don't reach comfortable swimming range until late June or early July. Spring-fed or alpine lakes stay cooler all summer. The live forecast above shows current conditions.
