Marais des Cygnes River

The Marais des Cygnes River (/məˈriː də ˈsiːn/, /ˌmɛr də ˈziːn/, or /məˈreɪ də ˈseɪn/) is a principal tributary of the Osage River, about 217 miles (349 km) long, in eastern Kansas and western Missouri in the United States. Via the Osage and Missouri rivers, it is part of the watershed of the Mississippi River. The name Marais des Cygnes means "Marsh of the Swans" in French (presumably in reference to the trumpeter swan which was historically common in the Midwest.) The river is notorious for flash flooding. The river is referenced in the song "The River" by Chely Wright.
