#Colorado river is contaminated after mine cleanup goes wrong Workers from an environmental protection team have caused accidentally an environmental disaster releasing millions of litres of toxic wastewater into a river in Colorado.
And the Colorado river which waters much of southern California, has been suffering from 14 years of low flow.
The team gathered water samples from a research site on the Colorado river near the town of Rifle
Environmental flows for ecosystem services in rivers natural and novel Last spring, the Colorado river reached its delta for the first time in 16 years,
Professor Banfield and her colleagues sequenced the genomes of organisms found in ground water at a site beside the Colorado river in Rifle Colorado.
Scientists at first expected the groundwater to flush into the Colorado river and carry the dissolved uranium with it,
if it's the Colorado river that we're"killing"?"Pretty much every state west of the Rockies has been facing a water shortage of one kind or another in recent years.
But the Colorado river basinhich provides critical water supplies for seven states including Californias the victim of a slower-burning catastrophe entering its 16th year.
Wyoming, Colorado, New mexico, Utah, Nevada, Arizona and California all share water from the Colorado river, a hugely important water resource that sustains 40 million people in those states, supports 15 percent of the nation's food supply,
and helped raise national awareness of the longer-term shortages that are affecting the entire Colorado river basin.
Arcane laws actually encourage farmers to take even more water from the Colorado river and from California's rivers than they actually need,
But in both California and the larger Colorado river basin mismanagement of the water supply has left the West more vulnerable to both short and long-term changes in climate.
When officials divvied up rights to Colorado river water nearly a century ago, it happened to be a wetter period than usual.
and states are stillclaiming the same amount of water from the Colorado river that they always have hich is 1. 4 trillion gallons a year more than the river actually produces.
Farming and agriculture use more than 70 percent of the water that flows from the Colorado river to the seven river basin states.
though the plant (which generates more climate-warming gases than almost any other plant in the nation) will continue pumping Colorado river water to Arizona.
Will California cutbacks alleviate the larger Colorado river problem? California uses almost one-third of the entire Colorado river flow,
having a larger share than any other Colorado river basin state. California gets 16 percent of its surface waterater that comes from snowpack, streams and riversrom the Colorado river via two huge aqueducts.
The California Aqueduct runs beneath mountains into Riverside County and eventually toward Los angeles, providing a substantial supply for both L a. and San diego. The All-American Canal moves water along the tail-end of the Colorado river near the Mexican border, nourishing one of the state's most valuable agriculture areas,
Imperial County, where a large proportion of the nation's winter fruits and vegetables are grown. Of the seven basin states, California holds the most senior legal rights to the Colorado,
which entitle it to keep drawing water even as Lake Mead runs dry and the rest of the Colorado river states suffer through shortages.
That means in the short term, not much that California does will change the situation on the Colorado,
But should Colorado river shortages worsen to the point that the states ever re-negotiate that division of water
a reduction of California's Colorado river water rights could have a brutal impact on California's remaining supplies.
it could save as much water as flows through the Colorado river in an entire year. Regardless
consumers far away from the Colorado river basin might feel the pinch. Finally, California and the rest of the Colorado river basin amount to the world's seventh largest economy,
and contribute significantly to the country's GDP. When California struggles economically the nation is close behind.
