About Arkansas River at Dardanelle
Arkansas River at Dardanelle is a gauged river in the Lake Conway-Point Remove watershed, Arkansas.
The watershed
This reach drains an upstream area of 154,000 sq mi (398,858 km2), so changes here reflect a very large part of the basin above the station. In this part of Arkansas, the higher water usually comes in winter and spring, while later-season recession tends to be slower.
For anyone with a dock, intake, or boat ramp, that scale matters: local rain is only part of the picture, and rises can carry through from far upstream. The station’s 19 years on record give a useful look at how far the river can move within a season.
What the numbers say
The monthly pattern is clear. May is the highest typical month at 17.94 ft (5.47 m), while September is the lowest typical month at 5.99 ft (1.83 m). That is a typical annual swing of 12 ft (3.64 m), which is enough to change bank exposure, access points, and where fish hold along the margins.
The record high is 45.41 ft (13.84 m) in May 2019. The record low is 3.93 ft (1.2 m) in April 2011. Those two endpoints show the reach can be much higher or lower than the usual seasonal range, so fixed shoreline setups should leave room for both spread and drawdown.
Reading the hero number
The hero number on this page compares today’s reading with the median for this calendar day across the station’s record. That is more useful than raw elevation alone, because 17.94 ft (5.47 m) means something different in May than it does in September.
USGS runs the station, and the 19-year record gives the comparison enough context to separate an ordinary seasonal rise from something out of step for the date. For a landowner or angler, that is the reading to watch: not just how high the river is, but how it sits against its own history for this day.
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.
