The class III rapids takes place at the man-made Santa Rita Whitewater Park. The Lower Animas is a relatively mellow trip that includes class I, II, and III rapids. Salt River in a valley 2.5 hours from Phoenix.Green River through Desolation Canyon in Utah’s largest wilderness research area.Colorado River through Cataract Canyon in Canyonlands National Park.Colorado River through Castle Valley in Moab.Green River through Gates of Lodore in Dinosaur National Monument.Yampa River in Dinosaur National Monument.Upper and Lower Piedra River near Pagosa Springs.Mild to Wild runs multiple rivers throughout Colorado, Utah and Arizona. Gauges are installed on rivers in order to measure the CFS and that information can be found on city water data sites.Īt Mild to Wild, the classes of CFS are defined as follows:Ĭlass I: “moving water” will let you comfortably float down the river.Ĭlass II: “splashes” will get your legs wet just over the side of the boat.Ĭlass III: “wet and fun” rapids will get you soaked head to foot.Ĭlass IV: “big drops” will jump-start your heart as you paddle through the intense whitewater.Ĭlass V: “violent rapids” will really get your adrenaline pumping and often have to be portaged.Ĭlass VI: “impassable whitewater” means no one has rafted that section and lived to tell. Depending on the waterway’s descent, width and arrangement of the rocks, a higher CFS can usually means you’ll get larger rapids.Ī river, in the Southwest especially, is considered to have high water levels when the CFS is 3,000 and above. The higher the CFS, the higher a river will be. One cubic foot is about the size of a basketball, so if a stream is flowing at 100 CFS, imagine 100 basketballs rolling down a riverbed together.

Wondering what is CFS when it comes to rivers? CFS is “cubic feet per second,” a unit of measurement referring to the volume and speed of water flow.
