Shallower areas tend to have the most rapids, while deeper water tends to be calmer.

The primary reason for building the Glenn Canyon Dam was to prevent silt from building up behind the Hoover Dam.

The dam has actually had a negative affect on the ecology of the area because the water no longer floods low lying areas, the water is colder an native fish can’t survive the new colder water.
