Whats New at Cedar Island Marina?

  • Clinton Harbor New Pumpout Boat
  • Clinton Harbor finally has a Pumpout Boat

  • Clinton Harbor FINALLY has a Pumpout Boat!

    Coastal Environmental Services Inc. (CES) and Cedar Island Marina are pleased to announce the introduction of a marine pumpout boat, which will service marinas in Clinton Harbor, Madison, Westbrook, and Old Saybrook. Clinton Harbor is home to one of the busiest recreational boating areas in Connecticut, comprised of over 10 marinas with almost 1,000 boats berthed in the harbor and contiguous rivers during the summer. 

    A partnership between the Connecticut River Department of Health, The East Shore District Health Department, CES, the towns of Clinton, Old Saybrook, Westbrook, The State Department of Environmental and Energy Protection, and Cedar Island Marina has made this service possible for boaters in the area. Funding for 75% the pumpout services comes from the Sportfish Restoration Program. The remaining 25% of the funding is going to be provided through user donations and town contributions. 

    The arrival of the pumpout boat addresses the ongoing concern of boaters dumping their waste into the harbor. Before the boat, the only way to discharge waste was to drive a vessel to a shore based facility, like the fuel dock at Cedar Island Marina. A pumpout boat allows for faster, direct service to the user, without the hassle of having to move their boat. Additionally, CES uses a secure on-line reservation system ( that enables boaters to request immediate, on-demand pumpouts, and also schedule pumpouts in the future. All these aspects make clean discharges easy for boaters, reducing pollution into the Long Island Sound.

    Enforcement of dumping waste overboard is hard as often times the dumping takes place outside of regular hours of operation, with few people around. The addition of the pumpout boat should alleviate most illegal dumping, making Clinton waters clean and healthy.

    The boat is partially funded by CT DEEP, allowing free service for all boaters. Users can register online and immediately begin scheduling pumpouts. The boat will be operational Memorial Day with regula operating hours from 9:00am – 7:00pm Saturday and Sunday. The vessel will be berthed at Cedar Island Marina, though any boater in the area can use it. To schedule a pumpout call 860-514-7664, hail on VHF Channel 68, or register online at More information about the program can be found Program support can be made at

  • Western Side of Outer Marina Dredged

  • April 29, 2013

  • After Mobile Dredge completed the channel dredging, we hired them to dredge the outer end of the marina where we had a large buildup of silt due to Irene and Sandy. They dredged from the outer end of H dock to the end of K dock. The shallowest depth now is 8' MLW.

  • Clinton Channel Fully Dredged

  • March 28, 2013

  • This past winter, Mobile Dredging & Pumping Company was awarded a contract by the Army Corps of Engineers to restore the channel to its original size. This means that the channel is AT LEAST 8’ deep at mean low tide and 100’ wide. After a few weather and political setbacks, Mobile Dredge was able to complete the job. The dredging effort was a joint project with CT Department of Environmental Protection to restore beach erosion at Hammonasset State Park. The dredge was hooked up to a pipe that was approximately 2.5 miles long and the sand at the bottom of the channel was pumped onto the beach. All of this means that we will be able to accommodate (even at low tide) boats with a deeper draft than before!
