My youngest daughters favorite fishing hole for fair weather fishing. We used to drift from the ramp area to the mouth in the summer catching a mixed bag of bass, pickerel, sheep head and cats. Upper Saugeen can provide muskie, pike, bass, bows, browns, speks and I've come across jet black bows in the past. Not sure what thats about.
Used to have a good run of skamania in the summer but I havent seen one in some time.
There are access points all over the Saugeen. Stop in at Thorncrest Outfitters for info. Canoes and kayaks are the only way to travel the upper. I think there's about 150kms of river not including the endless nameless tributaries.
