grizzly to two rivers is 2+ to 3--- in spots. Quick run at 5K...could take it down to tibbits or new castle.
Also try parkdale above the royal gorge (put in below three rocks), milk run on the arkansas (Johnson village (285 bridge right at AAE) to ruby mtn campground), stone bridge to salida on the arkansas, Deckers, Lower Blue (above 1k there is solid 3 boating a few spots), cemetary run on the roaring fork.
you can find good info in Colorado Rivers and Creeks! Have fun
