What is somewhat interesting is that the NF Skok, above Cushman, has a mile or two available for anadromous fish as Staircase is likely a block. So, the river itself will produce Diddle-E-Squat for either Chinook or steelhead. Downstream, in the previously dewatered NF, you have the habitat. What above Cushion can do is produce anadromous sockeye, but that doesn't have the ESA gravitas of Chinook and Steelhead.
