I may be way off here, but I've stayed in a couple campgrounds in Townsenda along the Little River with my family, and it seems like I remember them letting people come in and shower for a fee. You could swing by the offices of some of those campgrounds and ask if they'll let you use their showers or not. I'd say you can find atleast one who will ask for two dollars and let you on your way.
