I have fished Duck, Green, and Long before but that was in a bass boat. Those are probably bigger than I can effectively fish in a canoe. I have been on Portage before but it has been 10 years at least, If I recall it looked like it should have a good bass population but I don't remember us doing all that well.
Thanks for the map link! I have been using googlemaps to look at smaller lakes but sometimes it is hard to see if there is an access site.
