Mississippi River>, river
Total streamflow across the Mississippi River>, was last observed at 3,368,189 cfs, and is expected to yield approximately 6,680,723 acre-ft of water today; about 114% of normal. Average streamflow for this time of year is 2,966,651 cfs, with recent peaks last observed on 2019-06-11 when daily discharge volume was observed at 7,577,143 cfs.

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.

Mississippi River>,
The Mississippi River is the fourth-longest river in the world, stretching over 2,300 miles from its source in Minnesota to the Gulf of Mexico. It has played a significant role in the history and development of the United States, serving as a major transportation route for goods and people. The river's hydrology is influenced by its major tributaries, such as the Missouri and Ohio Rivers, and it has been harnessed for hydroelectric power through the construction of several dams and reservoirs, including the famous Hoover Dam. The river has also been an important source of freshwater for agricultural irrigation and a popular destination for recreational activities such as boating and fishing. However, the river has also faced challenges, including pollution and flooding, which have had significant impacts on the surrounding environment and communities.

About the Mississippi River>,
Where does the data for the Mississippi 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.
