Rebuilding Habitat in the Grand Canyon

From the U.S. Geological Survey (USGS):

Rebuilding Habitat in the Grand Canyon

The Grand Canyon is a bit closer to how it was before one of the country’s largest dams was installed upstream. Three years of releasing water from Glen Canyon Dam to generate controlled floods has resulted in rebuilding sandbars in the Grand Canyon. These simulated floods redistribute sand and mud, which helps develop this critical feature.

Sandbars are an important part of the Colorado River ecosystem. They provide habitat for native and endangered fish, sand that supports vegetation and helps protect archeological sites, and the flat ground provides great camping spots under the stars.

**How many images can you use? Here are two cool comparison photos:

And this is a dramatic one of the Grand Canyon with a sandbar.
