Navajo water a wild card in river's future
The commission that created the 1922 Colorado River Compact knew that Mexico, the Navajo and other tribes had rights to the river, but when it divvied up the presumed 15 million acre-feet annual flow, it didn't define the claims....Still no mention of Indian tribes, even though an 1850 treaty with the Navajo Nation, reinforced by a 1908 Supreme Court ruling, guaranteed water rights necessary for a permanent homeland Full Story »

Those unfamiliar with the Colorado Plateau, the River and the desert southwest will be hard-pressed to understand just how critical this issue is. The Colorado River runs 1,450 miles from the western Rocky Mountains to the Gulf of California, draining roughly 242,000 square miles of land, including Wyoming, Colorado, Utah, New Mexico, Arizona, Nevada, and California. The river is the major source of residential and commercial water supplies, irrigation and hydropower in the western desert. Though it passes within 800 feet of uranium mine tailings near Moab, Utah, no radioactive leaching has yet been reported. The river is a major force and attraction in most of the southwestern national parks: Arches and Canyonlands, and its 6-million-year handiwork, the Grand Canyon. Today, the river still runs wild through the 277-mile long canyon, until it reaches Lake Mead at the boundary between Arizona and Nevada. The river then defines the boundary between Arizona and California, in a series of hydropower dams and lakes providing recreation, municipal water and irrigation for Nevada, Arizona, and southern California. Since the 1920s, Nevada, Arizona, California, and Mexico have fought fiercely over water rights from the river to provide for growing cities and agriculture. At issue are both the quantity and quality of the river's diminishing supply of water. The Colorado River Basin has seen rising temperatures since the 1970s, and has warmed more than any other area in the USA. Rising heat, drought, and earlier snowmelt have reduced water volume in the basin, which now has seen seven consecutive years of below-average water flow. Lake Powell, one of the largest reservoirs, is less than half full. Throughout more than 80 years of river exploitation, the Navajo have scarcely been considered in the river's management, and have been bypassed by the water, the power, the crops, and the wealth the river provides. It is their turn to get what they need by exercising their rights.
