About South Tyger River below Duncan
South Tyger River below Duncan is in the Tyger watershed in South Carolina.
Season by season
This station fits a rain-driven pattern: higher water tends to show up in late winter and early spring, while late summer is usually lower. The typical high month is March, at 4.53 ft (1.38 m), and the typical low month is September, at 3.75 ft (1.14 m). That gap is 9.4 in (23.8 cm) across the year.
For anyone using the river, that means the channel usually gives more room in March and less in September. A dock, bank access, or shallow crossing has to live with that seasonal shift. In a dry warm stretch, the September level is the one to watch.
Records and rises
The record high is 14.78 ft (4.5 m) in September 2024. The record low is 2.33 ft (0.71 m) in August 2002. Those two numbers show the spread this station can reach when the weather leans hard one way or the other.
With 25 years on record, this site has enough history to show that late-summer records can still run high, not just low. That matters for flood-watchers and riverside owners: a tropical storm or other heavy rain can change the river fast, even in a season that often runs low.
No fastest 24-hour rise is listed here, so there is nothing to compare for warning time.
Reading the hero number
The number on the page is today’s reading. It is most useful when compared with the median for this calendar day, because that shows whether the river is running above or below its usual level for now.
That is more useful than raw elevation alone. A single height does not say whether the river is high for this date, low for this date, or near normal.
This station is published by the USGS, and its record extends over 25 years.
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.
How Nibi Metrics works · Water stories
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.
