Powell Climate Data
Gradient
Thanks to our location in in the Bighorn Basin with the Absoroka Range of the Rocky Mountains to our West and the Bighorn Mountains to our East, the Powell Valley is known as the "Garden Spot" of Wyoming. Located at 4300 feet above sea level, evenings are cool and mornings crisp. Powell boasts nearly 300 days of sunshine, July average high temps at 85, January lows of 8, and an average rainfall of only 6.2 inches. If you think that means snow, you'd be wrong. We average only 16 inches of snow per year!

Thanks to snowfall in the Absorka Range, ample water is available for agriculture and manufacturing from the Buffalo Bill Reservoir which holds the runoff. Water is delivered by the Northwest Rural Water District to cities around the Basin and by the Bureau of Reclamation's irrigation system.
