Average Water Levels

During the rafting season from March to October, the Colorado River’s water levels typically range between 1,000 – 50,000 CFS. Higher flows usually start in May, peak in June and trickle down thereafter. 

CFS stands for “cubic feet per second.” One cubic foot is about the size of a basketball. So if the Colroado is flowing at 1,000 CFS, imagine standing on the side of the river, watching 1,000 basketballs bounce past you every second.

Rapids

If your trip occurs during a period of high flows, you can expect a lot of class III rapids. High flows on the Colorado River are considered over 20,000 CFS.

If your trip is during a period of low flow, you can still expect class II rapids. Low flows can be considered below 5,000 CFS.

For trips taking place with medium flow rate, expect a mix of both, naturally!
