About Bellmore Creek Tributary at Bellmore NY
Bellmore Creek Tributary at Bellmore sits in the Southern Long Island watershed, New York.
The watershed
For people near the tributary, the useful pattern is the year-to-year range and the seasonal rhythm. The record high is 2.83 ft (0.86 m) in October 2017, and the record low is 0.65 ft (0.2 m) in September 2022. Those two marks show that this water can move through a fairly wide range even without a long river upstream.
The seasonal high is March at 2.21 ft (0.67 m), and the seasonal low is August at 1.58 ft (0.48 m). That is a typical annual swing of 7.5 in (19.1 cm). For a dock, bank access, or a shallow crossing, that swing is the part to watch through the year.
What the numbers say
The spring high in March fits the regional pattern of a freshet, while the late-summer low in August fits the usual summer recession. The record high in October 2017 and the record low in September 2022 sit outside that normal seasonal shape, which is useful to keep in mind when comparing a day’s reading with what is typical.
There is no fastest 24-hour rise listed here, so this station’s warning time cannot be stated from the provided facts. For practical use, the monthly pattern still matters: if you are judging freeboard, access, or low-water depth, the gap between March and August is the usual range to plan around.
Reading the hero number
The hero number on this page is today’s reading set against the median for this calendar day, not just the raw level. That comparison is better because a level that looks ordinary in March can be high in August, and a level that looks low in spring may be close to normal for late summer.
This station is operated by the USGS, and it has more than 50 years on record.
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.
