Ice Condition Three:

Coast Guard Sector Maryland-National Capital Region (NCR) Captain of the Port (COTP) is notifying mariners that conditions are favorable for the formation of ice in navigable waters. Within the Sector Maryland-NCR COTP Zone, as described in 33 CFR 3.25-15, navigable waters typically affected by early ice formation include the Chesapeake & Delaware Canal, Head of Chesapeake Bay and upper Potomac River.

All masters, ship agents, and owners and operators of all vessels, marine facilities and marinas are encouraged to report observed ice conditions to the Coast Guard Sector Maryland-NCR Command Center on marine band radio VHF-FM Channel 16, by telephone at(410) 576-2693, or via email at D05-SMB-SectorMD-NCR-SCC@uscg.mil, and should review and prepare for the seasonal ice procedures listed below. Ship agents should generally act as liaison between the Coast Guard and their vessels.

  • Vessel sea chests should be checked regularly for ice buildup and precautions should be taken to ensure that the sea chests are kept clear.
  • Vessel moorings should be checked frequently to ensure the vessel is adequately moored.
  • Vessels at anchor should maintain their engines on standby at all times, and should ensure that proper bridge watches are stood at all times.

When ice is present in navigable waters, excluding the Chesapeake & Delaware Canal, the regulations described in 33 CFR § 165.550 will be implemented. The COTP may set ice conditions for any safety zone listed, or a portion thereof, requiring vessels to meet the restrictions.

When ice is present in the Chesapeake & Delaware Canal, the Chesapeake City Resident Engineer (as representative of the District Engineer, U.S. Army Corps of Engineers, Philadelphia, PA) may prescribe conditions and requirements upon vessels using the waterway through the Canal Project dispatcher on duty.

Please refer to our daily ice Broadcast Notice to Mariners for current information regarding ice operations on marine band radio VHF-FM Channel 22A (broadcasted daily at 3 a.m.7:05 a.m.11:30 a.m.4 p.m. and 8:30 p.m. local times), or by calling the Sector Maryland-NCR pre-recorded “Ice Line” at (410) 576-2682.

Ice Condition Two:

Coast Guard Sector Maryland-National Capital Region (NCR) Captain of the Port (COTP) is notifying mariners that ice of noteworthy thickness and coverage has formed at the mouth and within the Chesapeake & Delaware Canal, the upper Potomac River, and on the Maryland Eastern Shore.

All masters, ship agents, and owners and operators of all vessels, marine facilities and marinas are encouraged to report observed ice to the Coast Guard Sector Maryland-NCR Command Center on marine band radio VHF-FM Channel 16, by telephone at (410) 576-2693, or via email at D05-SMB-SectorMD-NCR-SCC@uscg.mil, and should review the seasonal ice procedures listed below. Ship agents should generally act as liaison between the Coast Guard and their vessels.

  • Vessel sea chests should be checked regularly for ice buildup and precautions should be taken to ensure that the sea chests are kept clear.
  • Vessel moorings should be checked frequently to ensure the vessel is adequately moored.
  • Vessels at anchor should maintain their engines on standby at all times, and should ensure that proper bridge watches are stood at all times.

The COTP may set ice conditions for any safety zone listed the regulations described in 33 CFR § 165.550, or a portion thereof, requiring vessels to meet the restrictions. Vessels must have the proper hull type and an adequate propulsion system meeting the minimum horsepower requirements imposed.

The Chesapeake City Resident Engineer (as representative of the District Engineer, U.S. Army Corps of Engineers, Philadelphia, PA) has prescribed steel hull restrictions for the C&D Canal. The Canal Project dispatcher on duty should be contacted regarding conditions and requirements for vessels using the Canal.

Please refer to our daily ice Broadcast Notice to Mariners (BNM) for current information regarding ice operations on marine band radio VHF-FM Channel 22A (broadcasted daily at 3 a.m.7:05 a.m.11:30 a.m.4 p.m. and 8:30 p.m. local times), or by calling the Sector Maryland-NCR pre-recorded “Ice Line” at (410) 576-2682.
