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.

Middle Fork River
The Middle Fork River is a 92-mile long tributary of the North Fork of the American River in California. The river has a rich history, as it was once a significant source of gold during the California Gold Rush. The river's hydrology is heavily influenced by snowmelt in the Sierra Nevada mountains. The Middle Fork American River is impounded by the French Meadows Dam, which creates the French Meadows Reservoir, a popular recreational spot for fishing and boating. Additionally, the Oxbow Hydroelectric Project diverts water from the river to generate electricity. The Middle Fork River is also used for agricultural irrigation. Recreational activities on the river include whitewater rafting, kayaking, and fishing. The river is known for its challenging rapids and stunning scenery, attracting thousands of visitors each year.

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 Middle Fork River
Where does the data for the Middle Fork 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.
