Months of bitter negotiations between seven states that rely on the Colorado River’s vanishing water have collapsed along a clear fault line over the past week: California versus everyone else.
The multi-state talks, which have been ongoing in fits and starts for months, were focused on achieving unprecedented water cuts to save the Colorado River – a system that provides water and electricity to more than 40 million people in the West.
As less and less water has been flowing through the river and its reservoirs, US Bureau of Reclamation Commissioner Camille Touton last year called on the basin’s seven states – California, Arizona, Nevada, New Mexico, Colorado, Utah and Wyoming – to figure out how to cut 2 to 4 million acre feet of usage, or as much as 30% of their river water allocation.
If they couldn’t agree on how to do it, Touton vowed the federal government would step in.
On Monday, six states – including lower basin states of Arizona and Nevada – released a letter and a proposed model for how much Colorado River water they could potentially cut to stave off a collapse and prevent the nation’s largest reservoirs, Lakes Mead and Powell, from hitting “dead pool,” when water levels will be too low to flow through the dams.
The maximum amount of basin-wide cuts the six states are proposing in their model is 3.1 million acre feet per year. It accounts for water conservation and evaporation and, if approved, could kick in if reservoir levels fall to catastrophically low conditions.
California – the largest user of Colorado River water – is conspicuously absent from the text and will release its own letter and model calling for more modest annual cuts of around 1 million acre feet later this week, JB Hamby, the chair of the Colorado River Board for the state and an Imperial Irrigation District board member, told CNN.
