Everything you need to know about the locks on Lake Champlain to New York or via Oswego without forgetting the locks on the Chambly Canal
On the way to New York by Lake Champlain or Lake Ontario…
The Chambly Canal and other canals.
The new season is on the horizon.
The opening of the canals to New York via Lake Champlain or via Oswego via Great Lake Ontario will take place this year on May 19, 2023, from 7:00 a.m. to 5:00 p.m. each day. The 2023 season will end on October 11.
Some locks may close later than 5pm. You must contact them to see what hours they are open or extended.
They do have recruitment problems with personnel, so some locks may require contacting them in advance so that employees are present.
To contact them (New York State Canals):
You must not forget the limits in terms of height, what is called the air draft, you can also look at the technical data sheet of your boat and look under the name BRIDGE CLEARANCE or AIR DRAFT.
For the boats that use the Champlain Canal, the maximum air draft is 17 ft.
And for those going through Oswego (Lake Ontario), the air draft is 21.31 ft.
Of course, there may be variations.
For example, a bridge under repair can lower the available height by a few inches and sometimes more.
For the other data on lock dimensions, the length of each lock in the system allows for boats 300 feet long by 43.5 feet wide.
So the real difficulty is the height of the boat, from the water line and up.
