TheMohave Valley is avalley located mostly on the east shore of the south-flowingColorado River in northwestArizona. The valley extends intoCalifornia'sSan Bernardino County; the northern side of the valley extends into extreme southeastClark County,Nevada. The main part of the valley lies in southwestMohave County, Arizona and is at the intersection of the southeastMojave and northwestSonoran deserts.
The valley extends into the three states of California, Arizona and Nevada, and theFort Mojave Indian Reservation extends into them as well. On the west, the valley borders theDead Mountains of California which overlook the tri-state intersection point.
Needles onInterstate 40 lies on the southwest margin of the valley overlooking theHavasu National Wildlife Refuge andTopock Marsh. The village ofTopock is located at the south end of the valley where theChemehuevi Mountains of California restrict the Colorado to the narrowMohave Canyon.[1]
Mohave Valley is a 25-mile (40 km) long, north-south trendingvalley and up to 10 miles (16 km) wide at some areas.Mohave Valley, Arizona, in the center of the reservation, is at the center point of the valley.Bullhead City is at the northern perimeter of the valley;Needles is on the southwest border of the valley in California. Downstream, and southeast, near the southern valley perimeter is theTopock Marsh in Arizona, and also on the southern perimeter,Interstate 40 in Arizona as it ascends uphill out of theSacramento Wash, and eventually enters the entire north-southSacramento Valley which lies on the east, southeast, and partial south of theBlack Mountains.
Mohave Valley, Arizona, town center of the reservation, is located at34°57′25″N114°35′5″W / 34.95694°N 114.58472°W /34.95694; -114.58472; the town center is at the valleys center, and slightly west, closer to the Colorado River, the valley's west perimeter in many parts. TheBoundary Cone landmark, lies east, at the northwest perimeter of theBlack Mesa (western Arizona), a subsection mountain region at the southern end of theBlack Mountains.
The southern end of the valley begins elevated regions, with theMohave Mountains directly south, andDutch Flat, east of the Mohave Mountains, which drains northwest intoSacramento Wash. The southeast of the valley meets the outfall of Sacramento Wash, and associated drainage plains; Sacramento Valley itself is mostly east and south of theBlack Mesa section at the south of theBlack Mountains (Arizona); the Sacramento Wash turns due west, and followsInterstate 40 in Arizona as it turns west and parallels the wash to meet Needles at the Colorado River; it is also the southern drainage outfall point into theTopock Marsh, atTopock, eastern shore of the Colorado River, in the southeast valley. Other washes drain through the eastern Mohave Valley plains and foothills into the Topock Marsh from the southwest of the Black Mountains, the extensive range which goes north 75 miles (121 km) toLake Mead.
While in Arizona theSacramento Wash drains theSacramento Valley southwest ofKingman, in Nevada thePiute Wash drains thePiute Valley of southeast Nevada. A separate drainage lies between them on the Colorado River, theHavasu-Mohave Lakes Drainage.[2] These three drainages, the west, center, and east all drain into the Mohave Valley region.
