If #LakePowell’s Water Levels Keep Falling, A Multi-State Reservoir Release May Be Needed — #Colorado Public Radio #ColoradoRiver #COriver #aridification
FromColorado Public Radio (Michael Elizabeth Sakas):
Lake Powell’s water level is the lowest it’s been in decades, and the latest 24-month projections from the Arizona and Utah reservoir show that it’s likely to drop even further — below a critical threshold of 3,525 feet by next year.

A 20-year megadrought and a hotter climate has contributed to shrinking water supplies in the Colorado River. If Lake Powell’s levels continue to dwindle, it could set off litigation between the seven states and the 40 million people that all rely on the Colorado River.
“This is really new territory for us,” said Amy Ostdiek, deputy section chief of the federal, interstate and water information section of the Colorado Water Conservation Board…
States agree Lake Powell must stay above certain level
Ostdiek said it’s a “universally-accepted goal” among the seven states to avoid that situation. That’s why they agreed to the 2019 Colorado River Drought-Contingency Plan, which includes the provision that if Lake Powell drops below 3,525 feet, the upper-basin states and the Bureau of Reclamation have a plan in place to send more water to Lake Powell.
Those meetings are happening. Ostdiek said the upper-basin states have recently switched to planning mode due to the low water levels forecasted for Lake Powell. The plan to protect Powell could involve releasing water from upstream reservoirs of Flaming Gorge, Blue Mesa, and Navajo in Utah, Colorado and New Mexico.
But the hope is to avoid the need for that plan by keeping Powell above the 3,525-foot threshold.
