French River river
Maximum discharge along the river is currently at the French R At N Grosvenordale reporting a streamflow rate of 90 cfs. This is also the highest stage along the French River, with a gauge stage of 7.01 ft at this location. This river is monitored from 3 different streamgauging stations along the French River, the highest being situated at an altitude of 475 ft, the French River Below Dam.

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.

French River
The French River is a major river in Ontario, Canada, stretching 110 km from Lake Nipissing to Georgian Bay. It has a rich history, having been used by First Nations communities for thousands of years, and becoming an important route for fur traders in the 17th century. The river's hydrology is unique, with a series of interconnected waterways, rapids, and waterfalls. There are four major hydroelectric dams and reservoirs along the river, which provide electricity to the surrounding communities. The French River is also a popular recreational area, offering camping, fishing, and boating activities, as well as being a major tourist destination. The river also plays an important role in the region's agricultural industry, providing irrigation to local farms.

About the French River
Where does the data for the French 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.
