Sprague, built at Dubuque, Iowa's Iowa Iron Works in 1901 by Captain Peter Sprague for the Monongahela River Consolidated Coal and Coke Company, was the world's largest steam powered sternwheeler towboat.

[7] In 1975, the Sprague was moved to dry dock north of Vicksburg while negotiations for restoration funding proceeded.

[8] With restoration funding approved, the Sprague was moved from dry dock in March 1979 to a mooring site on the Yazoo River Diversion Canal north of Vicksburg.

The smokestacks and paddlewheel were removed, and in 1981, the Army Corps of Engineers demolished what was left of the Sprague using dynamite before clearing the metal debris from the canal.

[9] A model of Sprague is in the National Mississippi River Museum & Aquarium in Dubuque, Iowa.
