Duck River Flow
As of 2026-08-03, the Duck River is flowing at a combined 3,478 cfs across 7 USGS streamgauges — 109% of normal for this time of year, versus a seasonal average of 3,196 cfs.
Total streamflow across the Duck River was last observed at 3,478 cfs, and is expected to yield approximately 6,899 acre-ft of water today; about 109% of normal. Average streamflow for this time of year is 3,196 cfs, with recent peaks last observed on 2019-02-24 when daily discharge volume was observed at 252,740 cfs.
Maximum discharge along the river is currently at the Duck River Above Hurricane Mills reporting a streamflow rate of 1,590 cfs. However, the streamgauge with the highest stage along the river is the Duck River Above Milltown with a gauge stage of 11.08 ft. This river is monitored from 7 different streamgauging stations along the Duck River, the highest being situated at an altitude of 922 ft, the Duck River Below Manchester.

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.

Duck River
The Duck River is an approximately 284-mile-long river located in Middle Tennessee. Historically, the river was used by Native American tribes for fishing and transportation. It was also a significant route for early explorers and settlers. The river is known for its diverse aquatic life and serves as a major source of drinking water for nearby cities. The river has several reservoirs and dams, including Normandy Dam and Tims Ford Dam, which provide hydroelectric power and recreational opportunities such as fishing, boating, and swimming. The river also supports agricultural activities, including crop irrigation and livestock watering. However, pollution from agricultural runoff and urbanization has impacted the water quality in recent years. Conservation efforts are being made to protect this valuable resource.

About the Duck River
How is the Duck River flowing right now?
As of 2026-08-03, the Duck River is flowing at a combined 3,478 cfs across its USGS streamgauges, about 109% of normal for this date. The live per-gauge breakdown and 24-hour trend are shown above.
Is the Duck River running high or low right now?
Check the percent-of-normal figure on this page: above 100% means the river is running higher than its seasonal average for the date, below 100% means lower. The per-gauge table shows which reaches are highest and lowest.
Where does the data for the Duck 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.
