Arve Arve The river Arve () flows for approximately 100 km (62 miles) through France, in the "département" of Haute-Savoie, and (for a few kilometers) in Switzerland. It is a left tributary of the Rhône. Rising in the northern side of the Mont Blanc massif in the Alps, close to the Swiss border, it receives water from the many glaciers of the Chamonix valley (mainly the Mer de Glace) before flowing north-west into the Rhône on the west side of Geneva, where its much higher level of silt brings forth a striking contrast between the two rivers. The Arve flows through
Des Moines River from St. Paul, Minnesota to St. Louis, Missouri, passes over this section; the highway is designated Route 27 in both Iowa and Missouri, and was completed in the early 21st century. The Des Moines River rises in two forks. The West Fork (the main branch) rises out of Lake Shetek in Murray County in southwestern Minnesota. It flows south-southeast into Emmet County, Iowa, past Estherville. The East Fork rises out of Okamanpeedan Lake in northern Emmet County on the Iowa-Minnesota border and flows south, through Algona. The two forks join in southern Humboldt County, approximately 5 miles (8 km) south
