The important Wabash River connected the Great Lakes to the Ohio and Mississippi river valleys, and settlers used it for transportation and commercial purposes. In 1822, the Illinois and Indiana legislatures appointed William Polke and Thomas S. Hinde to survey the river to help plan improvements; and Congress authorized a survey in 1828. Abraham Lincoln and his family crossed the Wabash during heavy floods when they made their way from Indiana to Illinois in 1830. In 1834, Congress provided $20,000 for improvements, but President Andrew Jackson vetoed the bill. During the 1830s and 1840s, over 1000 flatboats navigated boats up and down the Wabash River, despite necessary improvements. Finally in 1849, the Wabash Navigation Company began construction on a lock and damn on the border between Indiana and Illinois, near Mount Carmel, Illinois.
