About SB Raritan R at Black Point Road at Neshanic Sta NJ
SB Raritan R at Black Point Road at Neshanic Sta NJ is a gauged river in the Raritan watershed, New Jersey.
What the record shows
The station has 17 years on record. The highest level in that record was 17.96 ft (5.48 m) in August 2011. The lowest was 3.98 ft (1.21 m) in November 2014.
The seasonal pattern is much quieter. March is the highest typical month at 5.16 ft (1.57 m), while November is the lowest typical month at 4.4 ft (1.34 m). The typical annual swing is 9.1 in (23.2 cm).
For someone watching a dock, bank, or crossing, that means this river usually moves within a fairly tight band, but the record can move well outside it. The high-water number is the one to keep in mind for wet spells and flood watches. The low-water number is the one to keep in mind for shallow margins, intakes, and anglers looking for steady depth.
The watershed
This reach drains 190 sq mi (492 km2) above the gauge. In New Jersey, the practical rhythm is familiar: winter and spring rain floods do most of the lifting, tropical systems and their remnants can bring the largest spikes, and summer usually brings lower flow.
For residents and river users, that seasonality matters more than a single reading. March is the month when the typical level is highest, and November is the month when it is lowest, so late-season water use and shallow access are worth watching.
Reading the hero number
The hero number on this page compares today’s level with the median for this calendar day at the USGS station, using more than 17 years of record. That is more useful than raw elevation alone because it puts the reading in context for this date, not just this day’s height in feet.
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.
