Okanagan CANADA-Kalamalka Lake-heading southbound through the canal to Wood lake...
Even on a good day..the canal is super tight...idling through when water's high..you may have to fold your tower or...it's about 3 inches clearance to the bridges..single boats at a time..about 4 feet deep trough blown out..rest is very shallow..anyone who's been there, driven through can appreciate the narrow margin for error even more!
BTW-These guys are pros...DO NOT try this at home!!!!
