Niangua Watershed Sampling Event

On May 7, the LMVP conducted a watershed-wide, single day water sampling event. The goal of the event was to collect samples from the Niangua River, several of its tributaries and the Niangua Arm of the Lake of the Ozarks. That's too much ground for our little laboratory to cover, so we enlisted the eager help of more than 20 people to visit sites in 5 counties. By the end of the day, volunteers collected and we processed 85 samples from as far north as the Highway 5 bridge to as far south as Interstate 44. We had a "field office" in Camdenton and another at Bennett Spring State Park that served as drop-off points and processing laboratories.

Sampling the entire watershed at once will provide a "snapshot" of water quality, removing nearly all variability associated with time. The result will be a decent picture of the variability across the area and should help us to locate problem areas in the considerably large range of the Niangua watershed.

The snapshot sampling won't tell us what the typical water quality of the Niangua watershed is like, but we'll know pretty well what it was like on May 7, 2011.

A full report will follow soon. If you want to be notified when it's available, send an email to

About the Niangua River:
The Niangua River flows northward from the city of Marshfield, just south of I-44, and runs for approximately 140 miles to the Osage Arm of Lake of the Ozarks. Many springs contribute water to the Niangua River, including Bennett Spring, which empties into the river about halfway along its course. In the last few miles before the river reaches the Lake of the Ozarks is Lake Niangua. Located at a bend in the river, Lake Niangua's Tunnel Dam provides hydroelectricity by discharging water 500 feet through a tunnel to a lower stretch of the Niangua. The Little Niangua River is the largest tributary of the Niangua, running nearly 60 miles before joining the Niangua Arm of the Lake of the Ozarks.
