Where Is the Sheyenne River in North Dakota?

The Sheyenne River is the longest river entirely within North Dakota, stretching approximately 275 miles (443 km) across the eastern portion of the state. It rises near Warwick in Benson County and flows generally southeastward, winding through the counties of Ramsey, Eddy, Foster, Griggs, and Traill. The river eventually joins the Red River of the North near Fargo in Cass County.

Fed primarily by snowmelt and rainfall, the Sheyenne drains a basin of about 10,000 square miles. Its flow is highly seasonal, with a pronounced risk of flooding during the spring thaw and summer storms. The river is a vital water resource for the region, supporting agriculture, recreation, and municipal supplies.
