Agreement Will Keep Mead & Powell Above Power Pool; AZ Will Be First To Lose Colorado River Water
EDIT
The Colorado River drought contingency plan aims to keep two key reservoirs, Lakes Powell and Mead, from falling so low they cannot deliver water or produce hydropower. It was negotiated among the seven states that draw water from the river. Mexico also agreed to store water in Lake Mead on the Arizona-Nevada border if the U.S. legislation was approved by April 22.
EDIT
Arizona has the lowest-priority access to Colorado River water and will be hit hardest. The state negotiated a separate agreement to provide other water sources and new groundwater infrastructure for farmers in Pinal County between Phoenix and Tucson.
Arizona and Nevada agreed to keep water in Lake Mead when it falls to certain levels. The cuts eventually would loop in California if the reservoir drops far enough.
The Metropolitan Water District, which supplies drinking water to millions in Southern California, agreed to shoulder Californias share of cutbacks if theyre needed. That pledge cut out the Imperial Irrigation District, which has the largest entitlement to Colorado River water and had said it would only participate in the arrangement if it secured money to resolve environmental problems at the shrinking Salton Sea.
