Hydrographic Engineering Icebreaking Operations

The Maryland Department of Natural Resources, Boating Services will have four vessels available during the 2022-2023 ice season. The icebreaking schedule listed below is the basic guideline to start the season noting that changes to the schedule may occur based on the severity of ice incurred this season. A heavy ice season may restrict our ability to reach every area on a regular basis due to each vessel's icebreaking capabilities, USCG restrictions, weather conditions, tidal levels and the possible need to relocate vessels to areas of greater demand.​

DNR ice breaking operations 

Requests for service should be directed to John Gallagher of Hydrographic Operations at 410-643-6521 or by cell phone 443-534-9610. You can e-mail the office John.Gallagher1@maryland.gov for specific instructions or emergencies. Information will be sent to the individual captains through our office.
