Data from American Whitewater & USGS
Description

A large island divides the river.  Both sides are blocked by dams. The dams create the usual death trap recirculations. Portage across the island down the middle for the easiest walking and access. The flat water from the dams extends upstream about one mile. 

Rancho Murieta Community Services district has large pumps and inlets on the north side of the river here.  The district diverts water from the Cosumnes River between November and May of each year to Calero, Chesbro and Clementia Reservoirs. All of the District's drinking water is treated before it is supplied to the customer.

Between the diversion dam and Hwy 16 are three or four small but interesting rapids.
