The Colorado River through the Grand Canyon.

Campsites along the Colorado River through the Grand Canyon will be in shorter supply because of flooding. The floods are actually part of a plan to increase fishing and restore the river to its more natural habitat.

A high-flow release from Glen Canyon Dam, upstream from the Grand Canyon, is scheduled to start today and end Friday

Sediment from river channels will be re-deposited downstream on sandbars and beaches along the river. Most of the sediment once deposited throughout the Grand Canyon now is trapped behind Glen Canyon Dam near the Arizona-Utah border.

The intent of the flooding is to mimic pre-dam conditions.

Grand Canyon officials say most campsites will be smaller and some low-lying sites might not be usable.

It's the third scheduled flooding under an experimental plan approved in 2012.
