36°28′48″N 92°55′0″W / 36.48000°N 92.91667°W Dubuque, Arkansas, was a town on the White River during the 19th century. White settlement began in 1814, and the town grew until the American Civil War. Dubuque's location at a river crossing and the presence of nearby lead mines drew attention to it during the war, and the town was destroyed during the fighting. Some postwar rebuilding efforts occurred, but it had mostly ceased to exist by 1870. The former location of Dubuque is now beneath Bull Shoals Lake.
