The Osage River is the 8th-largest river in Missouri. The river drains a mostly rural area of {{convert|15300|sqmi}}. The watershed includes an area of east-central Kansas and a large portion of west-central and central Missouri, where it drains northwest areas of the Ozark Plateau. The river flows generally easterly, then northeasterly for the final {{convert|80|mi}} where it joins the Missouri River. It is impounded in two major locations. Most of the river has been converted into a chain of two reservoirs, the Harry S. Truman Reservoir and the Lake of the Ozarks. DescriptionThe Osage is formed in southwestern Missouri, approximately {{convert|14|mi}} northeast of Nevada on the Bates-Vernon county line, by the confluence of the Marais des Cygnes and Little Osage rivers. (The Marais des Cygnes is sometimes counted as part of the river, placing its headwaters in eastern Kansas and bringing its total length to over {{convert|500|mi}}). The combined stream flows east past the Schell-Osage Wildlife Area into St. Clair County, widening into a long meandering arm of the Harry S. Truman Reservoir, approximately {{convert|40|mi}} long. The lake receives the South Grand River as a second arm of the reservoir from the northwest, as well as the Pomme de Terre River from the south. The two arms of the reservoir join near the Harry S. Truman Dam in central Benton County. Downstream from the Truman Dam, the river becomes the serpentine Lake of the Ozarks, stretching eastward for nearly {{convert|92|mi}} to Bagnell Dam in Camden County and southwestern Miller County. Constructed in 1931, the dam collects the Niangua River. Downstream from the dam, the Osage flows freely to the northeast in broad oxbow meanders through forested bluffs, joining the Missouri approximately {{convert|15|mi}} east and downstream of Jefferson City. HistoryThe river is named for the Osage Nation,[3] the historic indigenous people who dominated this region at the time when the first European settlers arrived. The river presented significant navigation difficulties for early settlers because of its fluctuating water levels, as well as the presence of shallow pools and sand bars caused by its tight meandering course through the hills. The Missouri Legislature attempted as early as 1839 to deepen the channel of the river. Early attempts failed because of lack of funding for the immense task. Commercial navigation on the river in the 19th century was confined mostly to smaller craft that could navigate the tight bends and shoals of the river. Improvements in the channel by the last two decades of the century led to greater commercial traffic. These changes made the lower reaches of the river navigable for steamboat commerce for a period of six to nine months out of the year. In the 20th century, federal construction of the Bagnell Dam, primarily to generate hydroelectricity, began in 1922 and was completed after nine years. It effectively ended commercial navigation on the river. The Truman Dam was authorized by the federal Flood Control Act of 1954 and was completed in 1979. The two dams on the river generate power for the St. Louis metropolitan area. The large reservoirs have become popular tourist destinations and recreation areas in the region. See also
