About Cross River at Katonah NY
Cross River in the Lower Hudson watershed, New York.
Season by season
March is the usual high-water month here, with a typical level of 1.85 ft (0.56 m). September is the usual low-water month, at 1.35 ft (0.41 m). That spread is a typical annual swing of 6.1 in (15.5 cm), which is the range a dock, pump intake, or shallow crossing should be ready to live with through the year.
That seasonal pattern fits the local rhythm: snowmelt and spring runoff build the year’s high water, then summer recessions pull the river down. For anyone watching a landing or fishing edge, the useful point is not just that the river changes, but when it tends to be highest and lowest.
Records and rises
The record high is 6.79 ft (2.07 m), reached in March 2011. The record low is 1.29 ft (0.39 m), reached in October 2015.
Those two marks tell you the range this station has actually seen over 32 years of record. If you use the river for access, a low reading near the October 2015 mark means shallow margins and tighter margins at crossings. A high reading near the March 2011 mark means the river can run far above its seasonal norm.
No fastest 24-hour rise is listed in the facts here, so there is no short warning-time number to lean on for this station.
Reading the hero number
The hero number on this page should be read as today’s level against the median for this calendar day, not against raw elevation alone. That comparison is better because it tells you whether the river is running above or below its usual position for this date, which is what matters for access, flooding concern, and fishing conditions.
This station is operated by the USGS, and the record spans more than 32 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.
