Opinion: Why Colorado is losing the water warThe dry 2020 and the lack of snow this season has water managers in seven states preparing for the first time for cutbacks outlined in drought contingency plans drafted two years ago.
A sobering forecast released this week by the Bureau of Reclamation shows the federally owned Lake Mead and Lake Powell — the nation’s two largest reservoirs and critical storage for Colorado River water and its 40 million users — dipping near-record-low levels. If those levels continue dropping as expected, long-negotiated agreements reached by the seven Colorado River Basin states in 2019 will go into effect, with water deliveries curtailed to prevent the federal government from stepping in and making hard water cuts.
The Bureau of Reclamation’s quarterly report was dire, showing Lake Powell at 42% of capacity and downriver’s Lake Mead at 40% capacity. And there’s not much water coming.
Opinion: Colorado’s intensifying drought conditions call for urgent collaborationThe Colorado River is under stress today due to rising temperatures and declining streamflows, as described in a Dec. 13 Colorado Sun opinion essay by Russell George and John Stulp. The other cause, seldom mentioned, is a water war among seven states, Mexico and the federal government — a war Colorado has been losing.
The 1922 Colorado River Compact called for dividing the river’s water equally between the Upper Basin (Colorado, northwestern New Mexico, Utah, Wyoming and far northeastern Arizona) and the Lower Basin (California, Nevada, the rest of Arizona, southwestern Utah and western New Mexico). In the compact, each basin was promised 7.5 million acre-feet of water each year. (An acre-foot is 325,851 gallons, enough to cover an acre, about the size of a football field, 12 inches deep.)
At the last minute, Arizona demanded exclusive use of water from the Gila River, which flows from New Mexico across Arizona to the Colorado River at Yuma. In 1945, a treaty with Mexico further unbalanced the deal. There’s more information here.
Governor Polis Activates Next Phase of Colorado Drought Plan, Prepares for Continued Severe Conditions into 2021Without a doubt, 2020 has been hot and dry in Colorado. The entire state and its nearly 5.8 million residents are living in drought conditions as evidenced by the record-breaking fire season, low river flows and shrinking water supplies.
The entire Colorado River Basin within Colorado is experiencing “extreme” or “exceptional” drought, according to the U.S. Drought Monitor.
The next few months are predicted to be warmer and drier than normal, which will further reduce snowpack runoff into our reservoirs even with a normal snowpack this winter.
Unfortunately, 2020 is not an anomaly; rather, it is a harbinger of a future to which we must adapt.
