Roe River flowing from Giant Springs
|Location||Great Falls, Montana|
|Length||201 feet (61 m)|
|Mouth elevation||3,245 feet (989 m)|
|Basin area||Missouri 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".
Starting in 2006 Guinness World Records did not list a shortest river.
- Finley, Carmel (1988-05-04). "D River Reclaims 'Lost' Title". The Oregonian. "Ginther said he determined that the D River flows from a fish control structure at the entrance of the lake west to where a huge driftwood log marks the point of extreme high tide, give or take five feet, and depending on sand elevation. That is 120 feet."
