Live river level, flow, historical records and forecast for Normans Kill at Karlsfeld NY in NY, United States, built from official government gauge data.
Normans Kill at Karlsfeld NY is a gauged river in the Middle Hudson watershed, New York.
This gauge watches 163 sq mi (422 km2) upstream of the station. With more than 11 years on record, it gives a usable local picture of how the river behaves through the year for people checking a crossing, dock, or intake.
In this part of New York, the seasonal pattern is the one to watch first. The river is typically highest in March at 9.44 ft (2.88 m) and lowest in September at 8.23 ft (2.51 m). That typical annual swing is 14.4 in (36.6 cm), so most years the water moves within a fairly tight band, but not so tight that you can ignore it.
The record high is 19 ft (5.79 m) in July 2026. The record low is 7.91 ft (2.41 m) in January 2018. Those two ends show that this gauge can move well outside its usual seasonal range.
For day-to-day use, the March-to-September difference matters because it is what a shoreline setup has to handle most years. The usual spread is modest, but the record high is far above the typical March level, so a low dock, launch, or bank-side access point should be checked with more than the average condition in mind.
The hero number on this page is meant to be read against the median level for the same calendar day across the station record, not against raw elevation alone. That comparison tells you whether today is running above or below what is normal for this date.
For a USGS station, that context comes from the United States Geological Survey. With more than 11 years on record, the calendar-day median is a better guide than a single height because it filters out the seasonal cycle and shows what is unusual for this time of year.
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.
