Live river level, flow, historical records and forecast for LAnguille River near Colt in AR, United States, built from official government gauge data.
L'Anguille River near Colt sits in the L'Anguille watershed in Arkansas.
The gauge drains 535 square miles (1,386 km2) above the station. That is the land area feeding this reading, not the whole watershed name on the page.
For people using the river, the main pattern is a winter rise and an autumn low. The typical high month is February at 11.97 ft (3.65 m), while the typical low month is October at 3.74 ft (1.14 m). The typical annual swing is 8.2 ft (2.51 m), so docks, pumps, and crossings here need to work through a wide range.
The record high is 16.76 ft (5.11 m) in April 2025. The record low is 2.28 ft (0.7 m) in October 2008. That span tells you this river can sit low for a time and also climb well above its seasonal high. For anglers, that changes access and current. For anyone with a pump intake or low bank use, it is the range that matters.
The USGS station has more than 50 years on record. That length of record makes the seasonal numbers more useful than any single reading. February tends to be the highest month, October the lowest, and the gap between them is the working band for this reach.
The record low in October 2008 and the record high in April 2025 show the river has reached both ends of a wide span. If you live near the banks, that is the practical story: low water can limit access, and high water can push conditions far above the usual autumn level.
The hero number on this page is best read against the median for the same calendar day across the USGS record, not as a raw elevation by itself. A single stage value only says where the water sits right now; the calendar-day median shows whether it is high or low for this date at this station.
That matters here because the river has a strong seasonal swing and a long record. With more than 50 years of USGS observations, the date-based median gives the clearest check on whether today is ordinary for this time of year or sitting outside the usual band.
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.
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.
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.
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.
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.
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.
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.
