About Tamiami Canal at S-355B near Miami
Tamiami Canal at S-355B near Miami is a gauged river in the Everglades watershed, Florida.
What the record shows
The station has 25 years on record, so the range here is wide enough to matter to anyone watching docks, pumps, or access points. The high-water mark is 9.57 ft (2.92 m), set in November 2020. The low-water mark is 4.24 ft (1.29 m), set in April 2016. That spread tells you this reach can move a long way between wet and dry periods.
Seasonally, the highest month is September at 8.15 ft (2.48 m), while the lowest month is May at 6.8 ft (2.07 m). The typical annual swing is 16.2 in (41.2 cm). For people living or fishing here, that means the water level usually shifts by enough to change bank access, depth at the edge, and how much water sits against a fixed structure.
The watershed
This gauge sits in the Everglades watershed, and the seasonal pattern fits a south Florida wet season. June through September is when convective storms and tropical systems are most likely to push levels up. Winter and spring bring the dry-season low flows, so May is the month to watch if you are planning around shallow margins or relying on steady water near the shore.
Because flat terrain drains slowly, higher water can linger for days after a run of rain. That is the part to remember if you are checking a low crossing, a pump intake, or a shoreline spot that can stay wet after the rain has moved on.
Reading the hero number
The hero number on this page is best read as today’s level against the median for this calendar day across the station’s 25 years on record, not just as a raw elevation. That comparison shows whether the canal is running ordinary for the date, or standing above or below its usual seasonal track.
This station is operated by the USGS.
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.
