shortest river

The world's shortest river, according to the Guinness Book of World Records, is the Roe River. It is only 200 feet (61 meters) long and flows between Giant Springs and the Missouri River near Great Falls, Montana. There has been debate, though, about which river is really the shortest. The D River in Oregon has been measured as being only 120 ft (37 m) long. It connects Devil's Lake directly to the Pacific Ocean near Lincoln City. Because the D River flows into the ocean though, it's length changes according to the tide so has been measured at several different lengths.
