Mariners are advised that as of Tuesday, September 4th the Mud Lock Boat Ramp on Cayuga Lake will be closed for the rest of the season for repairs.  This is not to be confused with Cayuga-Seneca Canal Lock CS1 in Cayuga, which is commonly and informally referred to as “Mud Lock” and hence the name of the boat launch immediately upstream of its upper approach wall.

Lock CS1 will be open every day of the week from 7am until 10pm through September 12th, and then 7am until 5pm through October 10th according to the lock and lift bridge schedule published at
