About Flatrock River near Raleigh, in
Flatrock River near Raleigh, in is a gauged river in the Flatrock-Haw watershed, Indiana.
The watershed
This station drains 58.1 sq mi (151 km2) upstream of the gauge. That is the area that responds here, not the whole Flatrock-Haw system.
With 15 years on record, the river has a short but useful history for tracking local swings. In this part of Indiana, winter and spring rain can keep water high when the ground is saturated or frozen, while summer storms can lift stages quickly and late-season flows often ease back.
For anyone crossing, farming nearby, or checking an intake, that upstream area is small enough that weather can show up in the gauge without much delay. The seasonal range is not huge, but it is enough to matter for low spots, bank access, and shallow reaches.
What the numbers say
The record high is 10.46 ft (3.19 m) in December 2013. The record low is 3.21 ft (0.98 m) in September 2015. Those two marks set the outer bounds of what this station has seen so far.
The usual high point comes in March at 4.19 ft (1.28 m), and the usual low point comes in August at 3.59 ft (1.1 m). The typical annual swing is 7.2 in (18.2 cm), so the river’s normal seasonal movement is modest compared with its record range.
For a dock, pump, or fishing access, that means the water often changes by inches rather than feet through the year, but larger jumps are still on the table during wetter periods. The river’s lowest typical water shows up in late summer, which is the stretch when shallow spots are most likely to be noticed.
Reading the hero number
The hero number on this page is most useful when it is compared with the median for the same calendar day, not just the raw height. A single water level can look high or low on its own and still be ordinary for that date; the day-of-year median puts it in context.
At this USGS station, that comparison is based on 15 years of record. That makes the daily median a better guide for judging whether the river is running near its usual level, above it, or below it 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.
