Roe River

The Roe River runs between Giant Springs and the Missouri River in Great Falls, Montana, United States. The Roe River is only 201 feet (61 m) at its longest constant point. Towards its end, the Roe becomes surprisingly deep, at least 6–8 feet. A successful campaign to get the Roe River recognized by the Guinness World Records as the shortest river in the world originated from students at Lincoln Elementary School in Great Falls, Montana. In 1988 Students Molly A. Petersen and future NFL football player Dallas Neil put in an appearance on The Tonight Show as part of this effort. Previously, Oregon's D River was listed in Guinness World Records as the world's shortest river at 440 feet (134 m). This title was lost in 1989 when Guinness, in what was then called The Guinness Book of Records, named the Roe River as the world's shortest. Not to be deterred, the people of Lincoln City submitted a new measurement of the D River to Guinness of about 120 feet (36 m) long, when marked at "extreme high tide.The D River regained the title of worlds smallest river ". Starting in 2006 Guinness World Records did not list a shortest river. Roe River at its mouth, flowing into Missouri River Interpretative sign at Roe River
