Finding the top signal on the water…
Live lake level, flow, historical records and forecast for Nolin Lake near Kyrock in KY, United States, built from official government gauge data.
Nolin Lake sits in the Upper Green watershed in Kentucky.
May is the usual high point here, with a typical level of 115.58 ft (35.23 m). December is the usual low point, at 92.62 ft (28.23 m). The typical annual swing is 23 ft (7 m), which is the range a dock, boathouse access, or shoreline setup has to live with over a normal year.
For people using the lake, that seasonal shape matters more than a single day’s reading. Spring levels are usually higher, while late-year water is usually lower. In a year with wet spells on already saturated ground, the lake can move outside that usual band quickly.
The record high is 159.65 ft (48.66 m), set in May 2011. The record low is 91.91 ft (28.01 m), reached in December 2025. That spread tells you this lake has seen a wide range over the record, from high-water shoreline pressure to very low water that can leave ramps, slips, and shallow coves less usable.
No fastest 24-hour rise is listed in the facts for this station, so there is nothing to quote there. The key point from the record is the size of the seasonal and event-driven changes, not a single daily jump.
The hero number on this page is best read as today’s level compared with the median for this calendar day across the station’s record. That is more useful than raw elevation alone because it puts the lake in its usual seasonal context. A level that looks high in winter may be ordinary for spring, and a level that looks low in spring may be more unusual than the same number in December.
This station has more than 17 years on record, and the data come from the USGS.
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.
