About Rockfish River near Greenfield
Rockfish River near Greenfield sits in the Middle James-Buffalo watershed in Virginia.
Season by season
The seasonal pattern here is simple to read. February is the usual high month at 3.45 ft (1.05 m), while September is the usual low month at 2.55 ft (0.78 m). That spread is 10.9 in (27.6 cm), which is the kind of change a dock, intake, or shallow landing has to live with across the year.
For this part of Virginia, winter and spring are the main flood season, so higher water is most likely when rain is frequent and soils are already wet. Summer can bring shorter low-water periods, and late-summer rises can still happen when tropical remnants send a lot of rain at once. That means a calm stretch in August or September should not be treated as a guarantee of calm water tomorrow.
The gauge drains 94.8 sq mi (246 km2) above the station, so local rain can move the line quickly compared with a larger river reach.
Records and rises
The record high is 10.12 ft (3.09 m) in January 2010. The record low is -0.03 ft (-0.01 m) in August 2008. That range tells you this river can sit near its seasonal low in late summer and also climb far beyond the usual monthly pattern when a major rain event arrives.
No fastest 24-hour rise is listed in the facts here, so I will not guess at warning time. The important takeaway is that the daily range can matter more than the calendar month when rain is heavy.
Reading the hero number
This page’s hero number is meant to be read against the median for this calendar day, not just as an absolute elevation. That comparison tells you whether today is running above or below what this station usually sees at this point in the year.
At a USGS station with more than 50 years on record, that context matters. A level that looks ordinary in feet can still be high for the date, or a low-looking number can be normal for late summer. The calendar-day median gives a better read for anglers, cottagers, and anyone judging access, depth, or runoff conditions on the Rockfish.
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.
