Live river level, flow, historical records and forecast for Middle Brook at Bound Brook NJ in NJ, United States, built from official government gauge data.

About Middle Brook at Bound Brook NJ

Middle Brook at Bound Brook NJ is a gauged river in the Raritan watershed, New Jersey.

What the record shows

The record in hand spans more than 16 years. The highest stage on file is 17.46 ft (5.32 m), set in September 2021. The lowest stage on file is 3.93 ft (1.2 m), set in June 2026.

The seasonal pattern is fairly tight. The typical high point comes in March at 6.22 ft (1.9 m), and the typical low point comes in July at 5.89 ft (1.8 m). The typical annual swing is 4 in (10.1 cm), so the usual move from one season to the next is modest even though the station has also seen much larger extremes.

For people along the brook, that means the gauge often spends long stretches near a narrow band, but it can still jump to a much higher stage when the record pushes hard. The difference between the monthly norm and the record high is the sort of change that can matter at crossings, low banks, and any spot that needs to stay passable.

The watershed

This station drains 17.2 sq mi (44.5 km2) upstream of the gauge. That is the area to keep in mind when reading local rain on the map and when judging how quickly the brook may respond.

In this part of the Mid-Atlantic, winter and spring rain floods are part of the pattern, and tropical systems or their remnants can bring the largest events. Summer usually leans lower. For a small drainage like this, that seasonal rhythm is what cottagers, anglers, and anyone with a low intake or a bank-side access point should watch first.

Reading the hero number

The hero number on this page is most useful when set against the median stage for this calendar day, not read as a raw elevation on its own. That comparison shows whether the brook is running above or below its usual level for the date, which is the more practical signal for a daily decision.

The station record is from the USGS, and this page draws on more than 16 years of observations to give that context.

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.

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.
