Finding the top signal on the water…
Live river level, flow, historical records and forecast for Mad River near Urbana OH in OH, United States, built from official government gauge data.
The Mad River near Urbana sits in the Upper Great Miami watershed in Ohio.
At this station, the upstream area is 162 sq mi (420 km2), so the reading reflects runoff from a fairly modest part of the basin rather than the whole river system. For people watching water levels here, that matters because changes can show up quickly after rain, and the gauge is tied to what falls and drains into the reach above it.
The highest level in the record is 7.85 ft (2.39 m), in May 2019. The lowest is 2.82 ft (0.86 m), in February 2026. That spread shows the range this site can move through over time.
The usual seasonal pattern is smaller than the record range but still useful for day-to-day planning. April is the highest typical month at 3.47 ft (1.06 m), while October is the lowest typical month at 2.97 ft (0.91 m). The typical annual swing is 6.1 in (15.4 cm). For dock users, anglers, and anyone with an intake or pump, that is the part to watch: the river usually changes by inches across the year, but storm periods can push it far beyond that.
I do not have a fastest 24-hour rise value for this station, so I cannot say how much warning a sharp jump has historically given here.
This USGS page is most useful when today’s reading is set beside the median for this calendar day across the record, not just the raw elevation. A single height by itself can hide whether the river is behaving normally for the season or sitting high or low for this date.
With more than 50 years on record, that comparison gives local context that matters for boating, shore access, and flood watching.
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.
