From KUNC (Luke Runyon):

Declining levels at the second-largest reservoir in the U.S. have spurred officials in Colorado, Utah, Wyoming, and New Mexico to search for ways to prop it up.

Lake Powell on the Colorado River is dropping rapidly amid one of the southwestern watershed’s driest years on record. It’s currently forecast to be at 29% of capacity by the end of September — the lowest level since the reservoir first started filling in 1963. Its sister reservoir downstream on the Colorado River, Lake Mead, is also approaching a record low this year.

The amount of water flowing to Lake Powell since October has been less than what the river delivered during the same period in 2002, the driest year on record. Total reservoir storage in the Colorado River basin is projected to be at 39% of capacity by the end of September.

Federal projections for the reservoir are prompting water officials to begin strategizing ways to keep Lake Powell from declining to a level where hydroelectric power generation is not possible. In a statement, the Upper Colorado River Commission announced it will begin developing a drought response operations plan, a measure outlined in a 2019 agreement. Earlier this year the reservoir’s declining level triggered monthly calls among the Upper Basin states and mandated a wider range of modeling.
