Live river level, flow, historical records and forecast for Great Miami River at Taylorsville OH in OH, United States, built from official government gauge data.
Great Miami River at Taylorsville sits in the Upper Great Miami, Indiana, Ohio watershed in Ohio.
This gauge has more than 50 years of record.
The highest level in the record was 27.23 ft (8.3 m) in December 2013. The lowest was 1.01 ft (0.31 m) in September 2024. That is a wide spread for one station, and it tells you the river can move from low, shallow water to a much higher stage that changes access, bank conditions, and the margin under low crossings.
The seasonal pattern is clear. The highest typical month is March at 4.68 ft (1.43 m), and the lowest typical month is September at 1.47 ft (0.45 m). The typical annual swing is 3.2 ft (97.7 cm). For people along the river, that is the range docks, intakes, and bank work have to live with from one part of the year to another.
The station drains 1149 sq mi (2976 km2) upstream of the gauge, not the whole named watershed. That is the area feeding this reading at Taylorsville.
For this part of Ohio, the seasonal rhythm is the main pattern to watch: higher water tends to show up in late winter and early spring, then lower water is more likely later in the year. When the river is rising from those seasonal lows, the change matters quickly for launches, shallow riffles, and any fixed intake set close to ordinary summer stage.
The hero number on this page is the current stage compared with the median for this calendar day from the USGS record at this station. That comparison is more useful than raw elevation alone because it tells you where today sits relative to what is normal here on this date.
Use it as a local context check: above the daily median means the river is running higher than usual for the season, while below it means lower than usual. In a river with more than 50 years of record, that is the cleaner way to read what the water is doing right now.
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.
