Notice to Mariners

Erie Canal – St. Johnsville to Whitesboro

August 25, 2021

Mariners are advised that Erie Canal Locks E-16 (St. Johnsville) to Lock E-20 (Whitesboro) that were closed in a previous Notice to Mariners have reopened to navigation.

Boaters should be aware of floating debris generated by recent heavy rainfall and proceed with caution, at a "No Wake" speed as some debris may be hard to see. Some buoys (Aids to Navigation) may be off station and are being relocated by Canal forces. Boaters should also verify overhead clearances at bridges before proceeding.

Boaters should also be aware that some areas of the Canal in this area may have reduced depths due to refill from recent storms, especially at creek mouths.  Surveys are planned and additional information on reduced depths will be published as it becomes available.  

Charts showing the affected areas can be found at  


Features along the Erie Canal are listed by mileage
