Finding the top signal on the water…
Live lake level, flow, historical records and forecast for Otsego Lake near Gaylord in MI, United States, built from official government gauge data.
Otsego Lake sits in the Au Sable watershed in Michigan.
For people around the lake, the useful frame is the seasonal range. The highest typical month is April at 3.5 ft (1.07 m), and the lowest typical month is September at 2.64 ft (0.81 m). That typical annual swing is 10.3 in (26.1 cm), so docks, lifts, and shoreline intakes need to tolerate a modest but real change through the year.
The record high is 4.57 ft (1.39 m) in April 2026, which is well above the typical April level. The record low is 0.99 ft (0.3 m) in September 2003, which is well below the typical September level. For anyone drawing water, launching a boat, or watching a shoreline edge, those two endpoints show the range the lake has reached in the station record.
This is a lake where April is normally the high point and September the low point. That is the pattern to watch when planning spring use, late-summer access, or anything that sits near the waterline.
The station has more than 40 years of record, so the seasonal pattern is not just a single wet year or dry year. The April peak and September low give you the usual rhythm; the record high and record low show the outer bounds the lake has actually reached. There is no fastest 24-hour rise listed here, so the short-term warning window cannot be stated from the available facts.
The hero number on this page is the lake’s current reading set against the median for this calendar day across the station record. That is more useful than raw elevation because it tells you whether today sits above or below the usual level for this date, not just how high the water is on an absolute scale.
This page uses the USGS station record, with more than 40 years on file.
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.
