About Site 9 in Conservation Area NO.1 in Boynton Bch FL

Site 9 in Conservation Area NO.1 in Boynton Bch FL is a gauged river in the Everglades watershed, Florida.

Season by season

The seasonal pattern here is not large, but it is measurable. The typical annual swing is 14.1 in (35.8 cm), so day-to-day changes matter more to docks, crossings, and shallow access than the absolute stage alone.

The highest typical month is October, at 16.97 ft (5.17 m). That fits the warm-season wet period in this region, when late-year storms can keep water up for longer stretches.

The lowest typical month is May, at 15.79 ft (4.81 m). For people using the water edge, that is the time when exposed banks, pumps, and shallow routes are most likely to feel the drop before the wetter months return.

Records and rises

The station record runs for 35 years, which gives enough history to see how far this reach can move. The record high is 17.92 ft (5.46 m) in November 1994. The record low is 14.41 ft (4.39 m) in June 2011.

Those two marks bracket the range this site has shown on the USGS record. For local users, that means the gauge has already seen both a notably high November and a notably low June, so the seasonal cycle is not the whole story; individual storms and dry stretches still matter.

Reading the hero number

The number at the top of the page compares today’s stage with the median for this calendar day across the USGS record, rather than showing raw elevation by itself. That is more useful because the same height can mean something different in October than it does in May.

With more than 35 years on record, the median gives a steadier yardstick for this site. It helps a boater, angler, or landowner judge whether the river is behaving normally for the date, not just whether the water surface is high or low in the abstract.

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.

The flood of record that was overtaken
