Two members of Arizona’s congressional delegation introduced legislation Tuesday on a plan to address a shrinking supply of water from a river that serves 40 million people in the U.S. West.
Republican Sen. Martha McSally and Democratic Rep. Raul Grijalva vowed to move identical bills quickly through the chambers. Bipartisan lawmakers from Colorado River basin states signed on as co-sponsors, including both of Colorado’s senators, Democrat Michael Bennet and Republican Cory Gardner.
“In the face of long term drought, the basin states have come together to create coordinated plans that should aid efforts to prevent severe water shortages in the west and stabilize water storage levels at Lake Mead and Lake Powell,” Gardner said.
Arizona, California and Nevada in the lower basin and Colorado, New Mexico, Utah and Wyoming in the river’s upper basin spent years crafting drought contingency plans. They aim to keep the two key Colorado River reservoirs from falling so low that they cannot deliver water or produce hydropower.
State water managers and federal officials have cited a prolonged drought, climate change and increasing demand for the river’s flows as reasons to implement a plan that would run through 2026 when current guidelines expire.
Bennet praised the work of the states on the drought plan and said it’s now time for Congress to “act quickly to safeguard Colorado’s agricultural and outdoor recreation-based economy.”
In the lower basin, the states would keep water in Lake Mead on the Arizona-Nevada border when it falls to certain levels. The cuts eventually would loop in California.
The states want congressional approval by April 22 so that Mexico also will contribute water starting in 2020.
The bills introduced Tuesday reflect language proposed by the states but also a section that says the implementation of the drought plan won’t be exempt from federal environmental laws.
The Imperial Irrigation District in California, which holds the largest entitlement to Colorado River water, and environmental groups had raised concern about draft language they took to mean federal laws like the National Environmental Policy Act and the Endangered Species Act would be disregarded.
Kim Delfino, California program director for Defenders of Wildlife, said Tuesday that the language eases their concerns, as long as reports accompanying the bills don’t undermine it.
