The Roseau River, located in Minnesota and Manitoba, Canada, is about 248 kilometers long. Historically, the river was used by the Dakota, Ojibwe, and Metis people for transportation and fishing. Today, it is used for recreational activities such as fishing, canoeing, and boating. The river's hydrology is primarily influenced by precipitation and snowmelt. The river is also impacted by three reservoirs: Roseau Lake, Malung Lake, and Pinecreek Lake, which are controlled by dams. These reservoirs are used for flood control, irrigation, and to supply drinking water. Additionally, the Roseau River is an important source of water for agricultural purposes, including irrigation for crops like sugar beets, potatoes, and soybeans. The river is an important natural resource for the region, providing recreational and economic benefits.
