Dam, powerhouse, and gauge are just upstream of put in. Runnable levels are assured virtually all summer.
'Maximum Recommended Flow' (10,000 cfs) represents levels well above the norm. The river has been paddled at virtually all flows. It should be noted, however, that high flows on this river are often accompanied with CSO (combined sewer overflows), so water quality will be an increased concern.
