Total streamflow across the Osage River was last observed at 7,100 cfs, and is expected to yield approximately 14,083 acre-ft of water today; about 35% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 20,009 cfs, with recent peaks last observed on 2015-12-30 when daily discharge volume was observed at 196,100 cfs.

Maximum discharge along the river is currently at the Osage River Below St. Thomas reporting a streamflow rate of 3,560 cfs. This is also the highest stage along the Osage River, with a gauge stage of 3.73 ft at this location. This river is monitored from 2 different streamgauging stations along the Osage River, the highest being situated at an altitude of 558 ft, the Osage River Near Bagnell.

The Osage River is a significant waterway that flows through Missouri and Kansas, stretching over 500 miles. It has a rich history, serving as an important trade route for Native Americans, French explorers, and early American settlers. Today, the river is heavily managed for flood control, with several dams and reservoirs, including the Truman Dam and Lake of the Ozarks. These reservoirs provide hydroelectric power, recreation opportunities like fishing and boating, and are important for agricultural irrigation. The river's hydrology is heavily influenced by precipitation, with flooding being a common occurrence. Despite this, the Osage River remains an important natural resource for the communities and industries that rely on it.

The Osage River is a 276-mile-long (444 km) tributary of the Missouri River in central Missouri in the United States. The Osage River is the 8th-largest river in Missouri. The river drains a mostly rural area of 15,300 square miles (40,000 km2). 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 80 miles (130 km) 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.
