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.

Collins River
The Collins River is a 67-mile-long tributary of the Caney Fork River in Tennessee. The river was named after Isaac Collins, who settled on its banks in the early 19th century. The river flows through rural areas and several small towns, including McMinnville and Rock Island. The hydrology of the river includes several tributaries, including Rocky River and Cane Creek. The Collins River is home to several dams and reservoirs, including the Great Falls Dam and the Rock Island Dam. These reservoirs provide hydroelectric power, flood control, and recreation opportunities for fishing, boating, and swimming. The river also supports local agriculture, particularly in the form of livestock grazing and crop irrigation. The Collins River is an important resource for the local community and a popular destination for outdoor enthusiasts.
Track the Collins 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 Collins River
Where does the data for the Collins 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.
