Chattooga River river
Total streamflow across the Chattooga River was last observed at 219 cfs, and is expected to yield approximately 434 acre-ft of water today; about 31% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 703 cfs, with recent peaks last observed on 2020-04-14 when daily discharge volume was observed at 29,640 cfs.
Maximum discharge along the river is currently at the Chattooga River Near Clayton reporting a streamflow rate of 219 cfs. However, the streamgauge with the highest stage along the river is the Chattooga River Above Gaylesville Al with a gauge stage of 4.15 ft. This river is monitored from 3 different streamgauging stations along the Chattooga River, the highest being situated at an altitude of 1,165 ft, the Chattooga River Near Clayton.

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.

Chattooga River
The Chattooga River is a 57-mile-long river that flows through Georgia, South Carolina, and North Carolina. It is known for its whitewater rapids and scenic beauty, as well as its role in several movies, including "Deliverance." The river is fed by numerous small streams and is regulated by several reservoirs and dams, including the Tugalo Dam, which creates Lake Tugalo, and the Chattooga Dam, which creates Lake Chattooga. These reservoirs are used for hydropower, flood control, and recreation. The Chattooga River is also used for fishing, swimming, and other recreational activities, and it provides water for irrigation and other agricultural uses. The river has a rich history, dating back to the Native American tribes who once lived along its banks, and it has been designated a National Wild and Scenic River for its unique natural and cultural features.

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