The Western Plateau Planning Area is composed of six groundwater basins located in northwestern Arizona. About half of the planning area lies in the part of Arizona north of the Colorado River referred to as the “Arizona trip”.  The planning area contains large tracts of federally protected lands including almost all of Grand Canyon National Park.  Elevations range from over 12,000 feet on the San Francisco Peaks to about 1,200 feet at Lake Mead.  Nearly half (46%) of Coconino County and 38% of Mohave County are contained within the planning area as well as all or portions of four Indian reservations including the Havasupai, Hualapai, Kaibab-Paiute and Navajo.

The planning area is relatively sparsely populated. The 2000 Census planning area population was approximately 17,500 with basin population ranging from just 12 in the Shivwits Plateau Basin to over 9,100 in the Coconino Plateau Basin. Colorado City is the largest community with about 4,150 residents in 2006.  Other population centers include Williams, Fredonia, Grand Canyon Village, the Beaver Dam/Littlefield area, and Cameron on the Navajo Reservation.

Between 2001 and 2005, an average of over 9,600 acre-feet of water was used annually in the planning area for agricultural, municipal and industrial uses (cultural water demand).  Of this total demand, approximately 6,000 acre-feet was from well pumpage, 3,300 acre-feet was from surface water diversions and almost 300 acre-feet was effluent reuse.  Agriculture was the largest demand sector with approximately 4,600 acre-feet of demand a year or 52% of the total demand. The municipal sector demand averaged about 4,000 acre-feet a year (AFA) and industrial demand averaged almost 1,000 AFA.
