The state’s top water authority will outline Wyoming’s role in the ongoing Colorado River Basin water crisis, including voluntary conservation and efficiency programs, at a public meeting Tuesday in Pinedale.

Though Wyoming declined to commit specific volumes to the U.S. Bureau of Reclamation’s call for 2023 water savings, the state’s water users in the Green River drainage — a tributary of the Colorado River — will likely be called upon to voluntarily curb water consumption in coming years, according to the State Engineer’s Office.

SEO officials will provide information about ongoing drought conditions, Wyoming’s rights and obligations under the Colorado River Compact and options to “prepare ourselves to not only mitigate impacts to our water users, but to potentially help offset negative impacts to the rest of the system,” Wyoming senior assistant attorney general for the SEO’s water division Chris Brown said.

The meeting will be from 2-5 p.m. Tuesday at the Sublette County Public Library.

Why it matters:

Two decades of drought exacerbated by human-caused climate change has sapped the Colorado River Basin water system that serves some 40 million people across the West and in Mexico. The two largest reservoirs in the system, Lake Powell and Lake Mead, shrank to historic lows this summer, threatening hydroelectric power production.

There’s simply not enough water in the system to fulfill the water allotments divvied among stakeholders by the 1922 Colorado River Compact, and the situation is expected to get worse, according to federal officials.

“Every sector in every state has a responsibility to ensure that water is used with maximum efficiency,” Interior Department Assistant Secretary for Water and Science Tanya Trujillo said in a prepared statement. “In order to avoid a catastrophic collapse of the Colorado River System and a future of uncertainty and conflict, water use in the Basin must be reduced.”

Among other strategies, Wyoming plans to resume participation in the federal System Conservation Program, which pays water users to curb consumption, according to the Wyoming State Engineer’s office. Congress recently re-appropriated funding for the program, while the Inflation Reduction Act includes some $4 billion for efforts to modernize Colorado River Basin infrastructure and water management practices. Another $8.3 billion from the bipartisan Infrastructure law is available to address water and drought challenges throughout the U.S.

History

To help make up for shrinking water levels in Lake Powell, the Bureau of Reclamation tapped Flaming Gorge Reservoir on the Wyoming-Utah border for an extra 125,000 acre-feet of water in 2021 and an extra 500,000 acre feet this year. Water levels at the reservoir are expected to drop by 15 feet total this fall.

“Every sector in every state has a responsibility to ensure that water is used with maximum efficiency.”

As one of three “upper basin” states, Wyoming’s plays an integral role in supplying water to the Colorado River system. Agriculture accounts for most of Wyoming’s water use in the system. However, Wyoming’s total water contribution mostly depends on seasonal climate and precipitation, Wyoming State Engineer Brandon Gebhart contends.

Those conditions have become more erratic, especially as average temperatures at Wyoming’s highest elevations — where seasonal snowpack serves as a “water bank” — warm at an alarming rate.

  1. typical for the states california & colorado for example: that have overbuilt & have high taxes to be
    demanding that the state’s that hes must make ave kept construction & taxes low wyoming for example :
    are demanding that those state’s make sacrifice’s to meet there demands.
    UNBELIEVABLE !
