Reservoir Recovery Does Not Erase Flood Damage

In this lesson: Evaluate whether water recovery proves that all drought has ended.

Name: __________________________ Date: __________________

Read the story

NASA’s November 11 account compares Landsat 9 images of Navajo Reservoir from September 20 and November 7. Water levels rose nearly 18 metres over that interval.

The storms eased short-term drought while causing destructive river floods. Long-term drought persisted in places, so fuller water storage was not evidence that every drought problem had ended.
