It flows westward along the county line between Pitkin and Eagle County. Below Meredith, it is dammed to form the Ruedi Reservoir. It joins the Roaring Fork below Basalt. A portion of the river's water is diverted to the east side of the continental divide for irrigation and drinking water via the Fryingpan-Arkansas Project.
