Fuel oil
There were a few regular carriers left by the 1920s, one of whom ran Jackson's Navy, using horses to tow the barges, and steam tugs after 1930. When the company stopped trading in 1948, sugar beet traffic was carried to Ely in boats owned by the beet factory for another ten years. Fuel oil for the pumping stations was supplied by the tanker barge "Shellfen" until 1971, by which time the Well Creek was almost impassible.
