River Description


The Upper Middle Cosumnes is an early spring run that is sought for the quality of its bedrock drops. 

 

The Cosumnes drainage is to the south of Highway 50 between the Mokelumne and American rivers.   It generally runs only in the winter or early spring since it does not have a high elevation drainage.   

Getting There:  The upper middle fork Cosumnes is near Sommerset, south of Placerville on Highway 50.  One route is to take Cedar Ravine Road south from Placerville to Bucks Bar Road to Summerset. 

 

Put in:   From Sommerset go east on Grizzly Flat Road, Right on Caldor, Right on 9N60 and follow to Dog Town Creek. Walk five minutes across Dog Town Creek and to the UMC.  This put in is on the river right. 

Warning: 
Put in options on river left are in question as local landowners have posted no tresspassing signs and have actively told boaters to go away.   Landowners intend to gate the put in road to prevent access by non land owners. (May 2010)    

Take out:  There are several take out options.   Rocky Bar Road on river right to the river is 4WD.  A Toyota Tacoma and Tundra bottomed out multiple times getting down there.  You may be able to drive most of the way down the right side take out road and then just hike your boats up a mile or less to the waiting vehicles.   Try the traditional river left take out with a 20 minute longer shuttle to get back over to river right and get to put in.

Another option that isn't bad is to continue on the river down to the bridge at Mt Aukum Road. It adds 4 or 5 miles of class 3 to class 2 floating.   If you're trying to save gas, this is a good option.
