The last day of operation at the Port of Dubuque Marina gas dock and convenience store for the 2024 season will be this Sunday, Oct. 13. End of season hours are 11 a.m. – 5 p.m. After Oct. 13, patrons who have already reserved a slip, or patrons with a seasonal slip, will still have access to other port amenities, outside of the gas dock. All currently un-reserved slips will be first come, first served. For the security of our seasonal boaters, the dock gates will remain locked until Oct. 31.
