Lake Powell

In Glen Canyon, home to Lake Powell, the shrinking reservoir has revealed areas that were once submerged. These scientists are counting the plants that live there, and have found that they're mostly native.

Water from Colorado’s Blue Mesa reservoir was sent to Lake Powell in the summer of 2021. It was an emergency move to help the second-largest reservoir in the U.S. keep producing hydropower.

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.
