6 western states agreed on a plan to make major cuts to water usage from the shrinking Colorado River, but California — the largest user of them all — wouldn't get on board

• The federal government has called on western states to come to agreement on water cuts.
• California couldn't come to an agreement with six other states on the Colorado River.
• The proposed cuts come as decades of drought have dwindled water supplies relied on by millions.

Western states failed to come to an agreement this week on how to cut water usage from the Colorado River, even as the waterway is drying up and failing to replenish the water supplies that cities, farms, and millions of people rely on.
