While they will lock you through locks on the Champlain and Erie Canals in a kayak or canoe, you might be looking for some long sections where you can paddle in quiet water without having to worry about going through the locks. By clicking on the balloons, you can find out the lock number.

The locks, bridges, gates, and other structures used to operate the canal system today were built between 1905 and 1918. Many remarkable remains of stone locks, aqueducts and other structures built during the 1800s are also visible along the canals.
East of Schenectady were two aqueducts which crossed and re-crossed the Mohawk River: The Rexford Aqueduct (or Upper Mohawk River Aqueduct) at Rexford, and The Crescent Aqueduct (or Lower Mohawk River Aqueduct) twelve miles downstream at Crescent.
In order to avoid steep, rocky terrain, Canvass White, C.E. devised the plan, approved in 1821, for the canal route to cross and re-cross the Mohawk River at Alexander's Mills (adjacent to Rexford) and at Fonda's Ferry (near Crescent). Continuing in operation until the new State Barge Canal System opened in 1916, a major portion of the Rexford Aqueduct was removed in 1918. The entire Crescent Aqueduct was removed in 1915, and nothing remains but a few stones at each end.
