Notice to Mariners


MAY 11, 2021

The New York State Canal Corporation today announced that engineers and contractors are working to repair a washout that occurred along the Ganargua Creek adjacent to the west abutment of the Ganargua Creek Aqueduct in the town of Macedon, south of Erie Canal Lock E-29. There is no threat to public safety; however, out of an abundance of caution, water levels within the nearby Erie Canal were drawn down. Updates will be provided as the repair work progresses.

In addition, the Erie Canalway/Empire State Trail has been detoured around the aqueduct. Trail users should follow the signed detour route.

 A chart showing the affected area can be found at
