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.

Cannon River
The Cannon River is a 112-mile-long tributary of the Mississippi River in southeastern Minnesota. The river was named after Colonel William Cannon, an early settler in the area. It starts in Rice County and flows eastward through Faribault, Northfield, and Cannon Falls before emptying into the Mississippi River near Red Wing. The river is known for its scenic beauty and has several popular recreational activities like kayaking, fishing, and camping. It also provides water for irrigation and agricultural use. The river has four main reservoirs - Shields Lake, Lake Byllesby, Lake Pepin, and Lake Tetonka - and several dams used for hydroelectric power generation. In the past, the river was used for transportation of goods, but today it serves primarily as a source of water for the local community.
Track the Cannon 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 Cannon River
Where does the data for the Cannon 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.
