The Upper Colorado River Planning Area is composed of nine groundwater basins located in northwestern Arizona, south and east of the Colorado River. Elevation ranges from 450 feet to 8,417 feet.  Most of the planning area is within Mohave County; the planning area also includes small portions of Coconino, La Paz and Yavapai counties.  Parts of the Fort Mojave and Hualapai Indian Reservations are within the planning area. The 2000 Census planning area population was approximately 162,100.  Basin population ranged from 823 in the Meadview Basin to over 51,500 in the Lake Mohave Basin.  Lake Havasu City is the largest metropolitan area with almost 42,000 residents in 2000. 

Annual cultural water demand averaged about 174,100 acre-feet (including effluent) during the period 2001-2005.  Agriculture was the largest water use sector in the planning area with an annual demand of approximately 99,550 acre-feet during this period, almost entirely within the Lake Mohave Basin.  Municipal demand accounted for about 52,400 acre-feet/year (AFA), and industrial demand averaged about 22,100 AFA.
