About Duck River near Shady Grove, TN.

Duck River near Shady Grove, TN. sits in the Lower Duck watershed, Tennessee.

Season by season

For most of the year, the river stays lower in September and higher in February. The typical level rises from 7.48 ft (2.28 m) in September to 12.33 ft (3.76 m) in February, a swing of 4.8 ft (1.48 m). For docks, pumps, and shallow crossings, that is enough change to matter through the year.

That seasonal pattern fits a river that responds to winter and spring rain. The month with the highest typical level is February, which is the time to expect the most water on this page. The lowest typical level is September, when margins are tighter for intakes and bank access. If you use the river for boating or fishing access, the late-summer low is the stretch that usually leaves the least room.

Records and rises

The record high on this station is 38.62 ft (11.77 m) in February 2019. The record low is 6.64 ft (2.02 m) in October 2016. Those two marks show how far the river can move at this site over the years on record.

This station has 11 years on record, so the extremes and the seasonal pattern come from a short but useful archive. Even without a fastest 24-hour rise in the facts, the river’s monthly pattern already tells you the main point: winter is the season to watch most closely, and September is usually the lowest-water month.

Reading the hero number

The hero number on this page is meant to be read against the median for this calendar day, not as a raw height on its own. That comparison is better because the same level can mean very different things in February and September. A river stage that sits near normal for this date can still be higher or lower than it looks if you only read the number in isolation.

This station is operated by the U.S. Geological Survey. With more than 11 years on record, the calendar-day median gives a better local reference than a single height does.

How this page is built

Readings come from official government gauges and are rolled into daily records: the daily mean, high and low for every day on record. Each calendar day gets its own baseline from the full history, so the level you see is compared against what this specific date usually looks like rather than an annual average.

Nibi Metrics - live water levels, flow, and forecasts for lakes and rivers across Canada, the US and the UK

Real-time water levels, forecasts, and alerts for lakes and rivers across Canada, the US and the UK. Built on official government data.

Nibi Metrics tracks more than 13,000 gauged lakes and rivers across Canada, the United States and the United Kingdom, reading directly from official federal monitoring networks: the Water Survey of Canada, the United States Geological Survey, Quebec's provincial hydrometric network, and the Environment Agency for England. Every number on the platform is measured, not modelled - taken from a government gauge on the water itself and compared against that location's own historical record for this exact date.

What you can see for any monitored lake or river

The level right now, in feet or metres, updated as the source agency publishes new readings - for many stations that is every five to fifteen minutes. How today compares to typical: every location carries its own typical-for-this-date band built from its historical record, so a reading is never just a number - it is above, below, or near what this water usually does on this calendar day. Which way it is moving: a measured RISING, FALLING, or STEADY verdict computed from the gauge's own recent readings, with the rate of change - the difference between a flood ending and one beginning. What comes next: level forecasts up to 72 hours ahead, driven by the gauge's recent behaviour, upstream water, and quantitative precipitation forecasts, alongside live radar, lightning, and weather for the surrounding region.

Alerts that watch the water for you

Set a threshold on any location - a level, a distance above typical, or a rate of climb - and Nibi emails or notifies you the moment the gauge crosses it. Cottagers use it for spring freshet, anglers for river conditions, marinas and municipalities for operations. The scanning runs around the clock against the same measured data shown on every page.

Where Nibi comes from

Nibi means water in Anishinaabemowin. The platform began at a family cottage on Lake Muskoka, Ontario, where the spring melt floods the shoreline most years and the only forecast was standing on the dock, looking, and guessing. It grew into an independent, member-funded platform run by Muskoka Research Inc. - no investors, no data resale, and a privacy policy shorter than most cookie banners. The core data is free for everyone, forever; paid plans add automation like multi-location alerts, deep history, and reports.

Coverage

Nibi spans the continent: every Canadian province and territory with active federal gauges - from Vancouver Island rivers to the Muskoka lakes, prairie reservoirs, and Quebec's hydrometric network - and the United States from Maine to the Texas Hill Country, the Ohio Valley, and the Pacific Northwest. Coverage grows where the water news is: when a basin floods, its gauges join the platform with their full historical records attached. Many stations report every five to fifteen minutes; most report at least hourly; every page states exactly when its gauge last spoke.

Free forever, funded by members

The core promise is simple: the water data is free, for everyone, forever. Live levels, maps, radar, and recent history never sit behind a paywall. Paid plans fund the platform by adding automation - multi-location alerts, decades of history, longer forecasts, and PDF reports - so the people who need more carry the cost for everyone who just needs to check the lake before driving up. There are no investors and no advertising deals shaping what the data says.

The flood of record that was overtaken

For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.
