A 150-foot barge with gravel on board is taking on water this morning in Nantucket Harbor, the US Coast Guard said.
No pollution has been released; marine inspectors are at the scene, said Petty Officer Connie Terrell, a Coast Guard spokeswoman.
The barge is tied to a pier owned by the Steamship Authority, at 1 Steamboat Wharf in Nantucket. The problem was reported by people on a tug boat next to the barge at about 9 p.m. Thursday.
Terrell said it was fairly uncommon for the Coast Guard to receive calls about barges taking on water.
No injuries have been reported.
