Roe River

The Roe River runs from Giant Springs to the Missouri River near Great Falls, Montana, United States. The Roe River is only 201 feet long at its longest constant point, and had been named as the World's Shortest River by the Guinness book of World Records before Guinness eliminated the shortest river category. Towards its mouth, the Roe is about 6–8 feet deep.

A successful campaign to get the Roe River recognized by the Guinness World Records as the shortest river in the world originated in 1987 with fifth-grade students of teacher Susie Nardlinger at Lincoln Elementary School in Great Falls. The river was unnamed at the time, so the students first had to petition the United States Board on Geographic Names to accept their proposed name, Roe River, then submit their proposal to Guinness. In 1988 future NFL football player Dallas Neil, then a student at the school, put in an appearance on The Tonight Show as part of this effort.
