The Havasu Canyon watershed covers approximately 500 square miles in northwestern Arizona and is part of the larger Colorado River Basin. The area is characterized by a semi-arid climate with low annual precipitation and high evaporation rates. The watershed is home to the Havasupai Tribe and their unique turquoise-colored waterfalls that draw thousands of visitors each year. The primary surface water source is Havasu Creek, which flows year-round and is fed by snowmelt from the surrounding mountains. Snowpack varies from year to year, with some years having significant accumulations while others have none. Reservoirs in the watershed are used for water storage and management. Interesting climatic trends include increasing temperatures and changes in precipitation patterns, which may have significant impacts on water availability in the future. Overall, the Havasu Canyon watershed is an important resource for both the natural environment and human communities in the region.
