About Tamiami Canal at S-12-B near Miami
Tamiami Canal at S-12-B near Miami is a river gauge in Florida’s Everglades.
Season by season
The seasonal pattern here is not subtle. The highest typical month is October at 9.68 ft (2.95 m), and the lowest typical month is May at 7.72 ft (2.35 m). That is a typical annual swing of 23.4 in (59.5 cm), which is enough to change how far a dock sits from the water and how steady a shallow intake stays through the year.
For anyone watching the canal, the dry-season low is most likely to show up in late spring, while the wetter season tends to build later in the year. In this area, that means the water can move from its seasonal low toward its seasonal high without much warning from one month to the next.
Records and rises
The record high is 11.75 ft (3.58 m) in January 1995. The record low is 5.03 ft (1.53 m) in June 1989. Those two marks set the range that long-time users of this gauge need to keep in mind: the canal can sit near its seasonal middle for long stretches, but it has also reached levels well above and below that band.
There is no fastest 24-hour rise listed in the facts, so I will not add one. What the record tells you is still useful on its own: this station has 50 years of record, so the seasonal pattern is not a short-lived snapshot.
Reading the hero number
The hero number on this page is the current reading compared with the median for this calendar day across the station record. That is more useful than raw elevation because the same level can mean different things in October than it does in May.
This station is operated by the USGS, and the long record behind it is about 50 years. For cottagers, anglers, and anyone managing pumps or access points, the day-median view answers the practical question: is the canal running higher or lower than usual for this date?
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.
