A 100-ton open caisson that was lowered more than a mile to the sea floor in attempts to stop the flow of oil in the Deepwater Horizon oil spill has been called a cofferdam. [citation needed] A cofferdam over 1 mile long was built to permit the construction of the Livingstone Channel in the Detroit River. [8] See main article at Stony Island.
