I have been down to 16 1/2 but not 16-will that be a problem in normal not flooding conditions? The Champlain N run has a clearance of 19 ft if I recall correctly. The lockmasters can play a little with water depths. That would also be the limit for the Erie canal to the Oswego and up to Lk. Ontario. The western part of the Erie has a 15 ft height restriction.
