Atchison's western boundary for the most part is the Missouri River and Nebraska. An 1867 flood straightened a bend in the river north of Watson. Both Nebraska and Missouri claimed the 5,000 acre McKissick Island that extends almost two miles into Atchison County. The Supreme Court in 1904 decided that the land belongs to Nebraska. The only way Nebraskans can reach it by road is to cross the Missouri River and then travel through Missouri.[6]
