South Grand River river
Total streamflow across the South Grand River was last observed at 3,812 cfs, and is expected to yield approximately 7,561 acre-ft of water today; about 124% of normal. River levels are high. Average streamflow for this time of year is 3,079 cfs, with recent peaks last observed on 2019-05-22 when daily discharge volume was observed at 39,700 cfs.
Maximum discharge along the river is currently at the South Grand River At Urich reporting a streamflow rate of 3,200 cfs. This is also the highest stage along the South Grand River, with a gauge stage of 15.37 ft at this location. This river is monitored from 2 different streamgauging stations along the South Grand River, the highest being situated at an altitude of 773 ft, the South Grand River At Archie.

Maximum streamflow discharge by year
The single highest aggregate discharge recorded each year. Spotting the multi-year trend reveals droughts vs. wet cycles long before the headline daily flow does.

Streamflow elevation profile
Each bubble is one gauge along the river, plotted by current streamflow (x-axis) vs elevation (y-axis), sized by gauge stage. Reading top-to-bottom traces the river from headwaters down to its mouth -- you can see flow accumulate as elevation drops.

South Grand River
The South Grand River is a major tributary of the Osage River in Missouri, USA. It stretches over 125 miles and is known for its rich history and diverse hydrology. The river flows through several counties and has been used for various recreational and agricultural purposes over the years. It is home to multiple reservoirs and dams, including the Harry S. Truman Dam and Reservoir, which was built in the 1970s for flood control, hydroelectric power generation, and recreation. The Pomme de Terre Lake is also located on the South Grand River and serves as a popular destination for fishing, boating, and camping. The river has played an important role in the state's history, serving as a source of transportation and commerce for early settlers. Today, it continues to support various agricultural communities and serve as a significant resource for outdoor enthusiasts.

About the South Grand River
Where does the data for the South Grand River come from?
Streamflow and gauge stage data are sourced from the U.S. Geological Survey (USGS) National Water Information System. The aggregate flow shown at the top of the page is computed by Snoflo as the sum of all monitored gauges along the river.
How is "percent of normal" calculated?
Today's aggregate streamflow is compared to the historical average aggregate streamflow on this calendar day across the river's full record. 100% means right on average; values above 100% indicate above-normal flow (wet year); values below indicate below-normal (dry year or drought).
Why are some gauges showing very different flows?
Gauges along a river measure flow at different points: headwater gauges read what's coming off the snowpack or mountain runoff; downstream gauges integrate everything upstream, including tributary inputs. Wide spreads usually mean a tributary is contributing significantly between gauges.
What's the elevation profile chart showing?
Each bubble is one gauge along the river, plotted by streamflow (x-axis) and elevation (y-axis), sized by gauge stage. Reading top-down traces the river from headwaters to mouth -- you can see flow build as elevation drops.
Can I get alerts when a specific gauge crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app on a per-gauge basis. Open any individual streamgauge from the table above and favorite it to set a discharge threshold.
