The Lock is scheduled to be open weekends one week prior to Memorial Day and then each weekend throughout the summer season.  We are open Saturday and Sunday from 9 am to 8 pm during the boating season.  The Lock will also be open the Friday of Corn Roast (August 12 & 13, 2022). The scheduled last weekend is two weeks after Labor Day.

Additional openings can be accommodated by appointment with 24 hour notice by calling 920-361-BOAT (2628) #1.

We are also open for personal tours, group visits and on site presentations of the History of Eureka Lock and Dam.  The Lock Tender and Crew are there to help!  NOTE:
