States file duelling Colorado River plans as water resources rapidly dwindle

California files competing proposal on cutting water use of the river as hopes of western states reaching consensus fade

California filed a competing conservation plan for the Colorado River on Tuesday, just one day after opting out of a proposal put forward by six other western states, signaling a breakdown in negotiations over how to drastically cut water use from the imperiled waterway.

Officials with the Bureau of Reclamation had called on the states to come to a consensus on how to curb between 2 and 4m acre-feet or roughly enough water to supply 8m households for a full year.
