About Unnamed Tributary to W B Rocky R near Berea OH
Unnamed Tributary to W B Rocky R near Berea OH is a gauged river in the Black-Rocky watershed, Ohio.
The watershed
This gauge drains 3.3 sq mi (8.6 km2) upstream of the station, so it is tracking a small reach rather than the whole Black-Rocky system. On watersheds this size, rain and snowmelt can show up quickly at the gauge, especially in late winter and spring when Midwestern streams often run high on wet ground. For anyone with a culvert, driveway crossing, or small intake nearby, that means short changes in stage can matter.
The station has 10 years on record, which is enough to show a repeat pattern but not enough to smooth out every odd season. The seasonal range here is modest: the typical annual swing is 3.3 in (8.3 cm). That is the scale of change a dock, low bank, or shallow outlet has to handle from one part of the year to another.
What the numbers say
The highest typical month is February at 2 ft (0.61 m). The lowest typical month is September at 1.73 ft (0.53 m). That lines up with a reach that tends to sit higher in late winter and lower by early fall, which is useful if you are planning angling access, bank work, or equipment placement.
The record high is 3.44 ft (1.05 m) in September 2020. The record low is 1.51 ft (0.46 m) in July 2022. Those two marks show the spread this small tributary can produce in a dry or wet spell, even within the same warm season.
Reading the hero number
The hero number on this page is today’s reading compared with the median for this calendar day across the station record. That is more useful than raw elevation because 2 ft (0.61 m) on one day can mean something different from the same height at another point in the year.
For this station, the comparison is built from the USGS record at usgs-04201409, with 10 years of observations behind it. If today sits above the calendar-day median, the reach is running higher than usual for this date; if it sits below, it is running lower. That is the cleanest way to judge what the river is doing right now.
How this page is built
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.
How Nibi Metrics works · Water stories
Nibi Metrics - live water levels, flow, and forecasts for lakes and rivers across Canada, the US and the UK
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.
What you can see for any monitored lake or river
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.
Alerts that watch the water for you
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.
Where Nibi comes from
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.
Coverage
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.
Free forever, funded by members
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.
