Lake of the Ozarks is a reservoir created by impounding the Osage River in the northern part of the Ozarks in central Missouri. Parts of three smaller tributaries to the Osage are included in the impoundment: the Niangua River, Grandglaize Creek, and Gravois Creek. The lake has a surface area of 54,000 acres (220 km2) and 1,150 miles (1,850 km) of shoreline. The main channel of the Osage Arm stretches 92 miles (148 km) from one end to the other. The total drainage area is over 14,000 square miles (36,000 km2). The lake's serpentine shape has earned it the nickname "Puff The Magic Dragon", which has in turn inspired the names of local institutions such as The Magic Dragon Street Meet.
