Boulder Creek, South

Guaranteed cold and clear!   Alto-Alto - Upper South Boulder Creek has great paddling fun from the get-go. This classic Colorado creek run can be accessed from a variety of launch points. Put-ins range from one to four miles above Rollinsville with tricky private land river access issues and a few man-made features. The river is alpine grade steepness near the Moffat Tunnel, rolling and falling away in sections. The river then begins pooling and dropping in stage pools from mining in the Tolland Valley.

After a boater has slid under HWY 119 you will pass the Rollinsville Yacht club on river right through the thick willow then the canyon tightens.

Hit the Opener surf wave then the rapids increase and the train feels like its in the river with you if you have the luck of hitting the rapid when the train is coming.

Rapid of Note: The U.P. Cascade: Eddy out river left to scout before the river turns back to the right and plunges down a cascade with a wall on river right and the train tracks on river left. This rapid differs tremendously between 350 and 600 CFS creating two river-wide ledges at higher flows that stomp. The static and unnatural shoreline on river left mirrors river right shoreline.

Spanky rapid is followed by a few tight turns and river splitting islands.

*Edge season fun-fact:  Long vertical icicles at head height near island splits bring on new meaning to ice cream headache.

In the exit of the canyon section a paddler will notice significant riverbed alteration as entering the private land owner whom has taken liberties with the streambed. The land owners in here (above the Icehouse property river left) have tried to create some trout habitat, apparently without consulting Gary Lacey about boulder placement.

\\ Unique Colorado river hazard: This is the only run in Colorado where kayakers can be run over by Semi Trucks while boating. (private land owner is trucking trailer loads of gravel out of the f
