Sunapee Harbor in New Hampshire Sees Two Oil Spills in Less Than a Week

By the Editorial Team · Wednesday, October 21, 2026

Emergency responders contained a second oil spill within a week in Sunapee Harbor, New Hampshire, though the source remains unidentified. Officials believe the spilled gear or hydraulic oil poses no threat to the town’s drinking water, and cleanup efforts are ongoing to prevent contamination of Lake Sunapee.

Emergency responders in Sunapee, New Hampshire, contained an oil spill in Sunapee Harbor on Monday afternoon, marking the second such incident at the site within a week. The spill, detected at 4:16 p.m., was observed near the Indian Cave Docks, The Blue Canoe, and along the shoreline close to the Wild Goose Country Store, according to a statement from the Sunapee Fire Department.

Despite extensive searches, crews were unable to locate the source of the spill. However, officials indicated there is likely no threat to the town’s drinking water supply. David Bailey, superintendent of Sunapee Water and Sewer, stated that the floating oil is unlikely to reach the water intake pipe, which is situated roughly 30 feet below the lake’s surface.

Preliminary assessments suggest the spilled substance may be gear or hydraulic oil, based on visual inspections by fire personnel and photographic evidence reviewed by the New Hampshire Department of Environmental Services (DES). A sample has been collected for laboratory analysis.

Containment efforts, including the deployment of floating booms to restrict the spread of the oil within the harbor and prevent it from reaching Lake Sunapee or downstream waters, were completed by 5:40 p.m. Cleanup operations began immediately but were paused due to darkness, with crews set to resume work on Tuesday. Officials have advised the public to avoid disturbing the containment booms until cleanup is finished.

This incident follows a hydraulic oil spill last Wednesday at the West Docks off Garnet Street, where a crane removing boats ruptured a hydraulic line. Fire crews contained and began cleaning that spill promptly, and authorities confirmed there was no known risk to the town’s water supply at that time.

Both the state DES and Sunapee Water and Sewer were notified of the recent spill incidents. Efforts to obtain additional comment from these agencies Monday evening were unsuccessful. Sunapee Harbor, located on Lake Sunapee in western New Hampshire, serves as a key resort and commercial area for the region.
