Live river level, flow, historical records and forecast for Cow C near Lyons in KS, United States, built from official government gauge data.

About Cow C near Lyons

Cow C near Lyons is a river in the Cow watershed, Kansas.

What the record shows

The record on this station runs for more than 50 years. The highest level in that span was 54.26 ft (16.54 m) in February 1989. The lowest was 0.43 ft (0.13 m) in September 1988.

That spread matters on the ground. A reach that can move from a low-water mark like September 1988 to a much higher crest like February 1989 can change quickly enough to alter access at crossings, shallow intakes, and bank lines. The typical seasonal range is smaller: the highest month is June at 4.95 ft (1.51 m), and the lowest month is September at 4.27 ft (1.3 m). The typical annual swing is 8.1 in (20.7 cm), so the day-to-day expectation is a moderate shift, not a big seasonal climb.

This is plains hydrology, so the main pattern to watch is a sharp rise after spring or summer storms, followed by a long drop between events. Flat ground slows the release of high water, so a rise can linger after the rain has passed.

The watershed

The drainage area above this station is 728 sq mi (1886 km2). That is the catchment feeding this gauge, not the whole watershed named in the map label.

For people along the river, that upstream area sets the scale for how much water can arrive after rain. On a small rise, the river may respond within a day or two. On a larger storm, the same channel can stay elevated longer because water from across that 728 sq mi (1886 km2) arrives in steps.

The seasonal record also fits a practical calendar: June is the usual high point, September the usual low point. For docks, low-water pumps, and bank access, that means the middle of summer can still be the low-stress period even when storms interrupt it.

Reading the hero number

The hero number on this page is the current stage at this USGS station, read against the median stage for the same calendar day across the record. That is more useful than raw elevation alone because it tells you whether today is running high or low for this date, not just how high the water sits above the datum.

With more than 50 years on record, that day-by-day context helps anglers and neighbours judge whether the river is near its usual range or moving outside it. If the page is showing a rise, the key question is how far it sits from the median for today, because that is the quickest read on whether conditions are ordinary or unusual for this date.

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.
