Speckled: "Water levels will be lower, bugs will be less. End of August crowds are similar to June crowds. Once you get into Sept, the crowds start to dwindle."
+1.
We did this route in the last days of August, 2022. No problem getting through other than a sandy shallow or two early on the Moose River requiring the bow paddler to get out for a minute and some additional rock garden to navigate on the Boulder River between Agnes and Boulder Bay. It was moderately crowded but there were sites on each lake. Enjoy.
