Map showing ground-water conditions in the Bodaway Mesa area, Coconino County, Arizona: 1977

The Bodaway Mesa area includes about 800 square miles in north-central Arizona, and most of the area is in the Navajo Indian Reservation. Ground-water development has been slight; in 1977 the estimated ground-water withdrawal was less than 5 acre-feet. The Chinle Formation is the principal aquifer tapped by wells, and in places the Moenkopi Formation and the Redwall and Muav Limestones yield water to wells and springs. Water levels in the Chinle Formation are 15 to 200 feet below the land surface. The water from one well completed in the Petrified Forest Member of the Chinle Formation contained 1,210 milligrams per liter of dissolved solids; the dissolved-solids concentrations from two wells in the Shinarump Member of the Chinle were 1,000 and 1,110 milligrams per liter. Three wells penetrate the Moenkopi Formation, but only one yields water. One well obtains its water from the Redwall Limestone, and the water level is 2,200 feet below the land surface. About 60 cubic feet per second of water is discharged by springs that issue from the Redwall and Muav Limestones along the east wall of the canyon of the Little Colorado River. Information on the map includes depth to water, altitude of the water level, specific conductance, and fluoride concentrations. Scale 1:125,000.

Map showing ground-water conditions in the House Rock area, Coconino County, Arizona-- 1976

The House Rock area includes about 1,500 sq mi in north-central Arizona. Ground water is present in several aquifers that are made up of one or more formations. In the Paria Plateau and Wahweap areas ground water is obtained from the N aquifer, which includes the Navajo Sandstone, Kayenta Formation, and Moenave Formation. Reported static water levels in wells range from 515 to 1,500 ft below the land surface. The chemical quality of the water in the N aquifer varies with location, and dissolved solids generally are less than 850 milligrams per liter. Several wells and test holes in the Lees Ferry area penetrate either the alluvium, Chinle Formation, Moenkopi Formation, or a combination of these. As of 1976, water from these wells was not being used because of poor chemical quality. In the southern and western parts of the area many springs discharge from te Kaibab, Redwall , and Muav Limestones. The quality of water from these formations generally is excellent. Information on the map (scale 1:125,000) includes the principal aquifer that furnishes water to individual wells and springs, depth to water, altitude of the water level, and chemical quality of the water.

Maps showing ground-water conditions in the northern part of the Chinle area, Apache County, Arizona, 1976

The northern part of the Chinle area includes about 3,000 sq mi in northeastern Arizona and is entirely in the Navajo Indian Reservation. The main source of water is from the several aquifers that are made up of one or more formations. The aquifers are stacked one on the other and generally are not hydraulically connected. Information on the maps includes depth to water, altitude of the water level, and chemical quality of the water. Scale 1:125,000. (Woodard-USGS)

Maps showing ground-water conditions in the Monument Valley and northern part of the Black Mesa areas, Navajo, Apache, and Coconino counties, Arizona, 1976

The Monument Valley and the northern part of the Black Mesa areas include about 2,700 sq mi in northeastern Arizona and are entirely in the Navajo and Hopi Indian Reservations. The main source of water is from the several aquifers that are made up of one or more formations. The aquifers are stacked one on the other and generally are not hydraulically connected. Information on the maps includes depth to water, altitude of the water level , and chemical quality of the water. Scale 1:125,000. (Woodard-USGS)
