The U.S. Snagboat Montgomery was designated a National Historic Landmark in June 1989. As one of the South’s last steam-powered sternwheelers, she was used by the U.S. Army Corps of Engineers to maintain seven navigable rivers. From 1926 to 1933, crews worked on the Coosa and Alabama rivers, using her derrick and grapple to remove snags and debris from the river channels. In 1933, she was transferred to the Black Warrior and Tombigbee Rivers. Her final work stations were the Apalachicola, Chattahoochee, and Flint rivers in Florida, Alabama, and Georgia, where she served until retiring in 1982. She is now permanently located on the bank of the Tennessee-Tombigbee Waterway at Pickensville, Alabama.
