Yes there are dollies in the Sauk. But as for native R/B I don't really know. I know the the N/F Sauk has natives as there is a falls on the river and the steelhead can't get over it. As for the S/F I really couldn't tell you,but I've caught fish up to 14" inches out of the S/F but that was when I was alot younger and could get to the out of the way places. Was up there about a week ago and had a ball on small cutts. My trips up there are like I'll go fishing now as it is close or Maybe I'll go. By being retired I get the whim and I'll go.
