The species was accidentally introduced into the Elkhorn River near Omaha, Nebraska in 1873, when a railroad car transporting East Coast fish to the West Coast lost its cargo to the river after a railroad bridge collapsed. All told, an estimated fifteen hundred eels from Martha's Vineyard and 40,000 from the Hudson River were released in the Elkhorn.
