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.

Grant River
The Grant River is a 46-mile-long tributary of the Mississippi River located in southwestern Wisconsin. It was named after President Ulysses S. Grant who lived in nearby Galena, Illinois. The river is fed by several small streams and flows through rugged terrain, creating scenic bluffs and valleys. The hydrology of the river is influenced by the surrounding karst topography, resulting in cool and clear water that supports a diverse fish population. There are several small reservoirs and dams along the river, including the Potosi/Wisconsin River Reservoir and the Grant River Dam. These structures provide flood control, water storage, and hydroelectric power. The river also supports agricultural activities, including crop irrigation and livestock watering. Recreational opportunities include fishing, boating, and hiking along the river's scenic bluffs.
Track the Grant River in the Snoflo app
Set per-gauge push alerts (e.g. "alert me when flow at the Russian R Nr Healdsburg crosses 5,000 cfs"), and Snoflo's iOS app pushes the moment USGS reports the crossing.
About the Grant River
Where does the data for the Grant 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.
