Information on fees and how to obtain a pass can be found at or by calling Canal Corporation Headquarters (between 8:00 am – 4:00 pm) at (518) 436-2799.


Lock C-11 on the Champlain Canal is located in the town of Comstock, nine miles north of Lock C-9. This scenic lock lowers boats 12 feet, from an elevation of 124 feet to 112 feet above sea level. The Lockmaster can be reached by VHF Radio channel 13 or by phone at (518) 639-8964. Lock C12 (and Lake Champlain) is only 7 miles away.
