Swimming River near Red Bank NJ Water Level

Live river level, flow, historical records and forecast for Swimming River near Red Bank NJ in NJ, United States, built from official government gauge data.

About Swimming River near Red Bank NJ

Swimming River near Red Bank NJ sits in the Sandy Hook-Staten Island watershed in New Jersey.

Season by season

This river’s typical high point comes in March, when the station’s median level is 5.26 ft (1.6 m). The typical low point comes in October, at 4.77 ft (1.45 m). That is a modest seasonal swing of 5.9 in (14.9 cm), so the day-to-day shape matters more than a large annual range for docks, small intakes, and shallow launches.

The regional pattern fits what nearby waters often do in this part of the Mid-Atlantic: winter and spring bring the higher water, while summer tends toward lower flow. For people using this river, that usually means the reach is more likely to sit up in late winter and early spring, and more likely to run leaner by late summer and into fall.

Records and rises

The highest level in the record is 7.02 ft (2.14 m) in August 2011. The lowest is 1.08 ft (0.33 m) in September 2015. Those two marks show that the river can move well outside its usual monthly band.

There is no fastest 24-hour rise in the facts provided here, so I cannot quote a warning-time number for sudden jumps. With a station drainage area of 49.2 sq mi (127 km2) above the gauge, local rain can still change the river quickly, but the size of that response is not stated in the record set I have.

Reading the hero number

The number on this page should be read against the median for this calendar day, not as a raw height by itself. A single elevation can look ordinary or unusual depending on the time of year; the day-specific median tells you whether the river is running above or below its usual level for that date.

This station is a USGS site with about 50 years on record, so the comparison is grounded in a long local history rather than a single storm or one wet season.

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.
