Live river level, flow, historical records and forecast for Cedar Creek at Woodstock in ON, Canada, built from official government gauge data.
Cedar Creek at Woodstock sits in the Upper Thames watershed in Ontario.
This gauge tracks the creek upstream of a catchment of 91.1 km2 (35.2 sq mi). That is the area feeding this station, not the whole watershed. For people near the water, that upstream size matters because the creek can answer rain and melt from a limited land area, so local storms can show up in the level record.
The record high is 4.59 m (15.05 ft) in January 2020, and the record low is 3.45 m (11.31 ft) in September 2016. Those two marks define the range this site has already seen.
The seasonal pattern is modest but clear. March is the highest typical month at 3.77 m (12.36 ft), while August is the lowest typical month at 3.55 m (11.64 ft). The typical annual swing is 21.8 cm (8.6 in). For dock owners, intake users, and anyone watching access points, that means the creek usually moves through a fairly tight band, but the site has still reached levels well outside the monthly typical range.
The regional pattern is snowmelt-driven: spring freshet late April-May, natural summer drawdown July-September, and early-winter decline as ice forms. That seasonal shape fits the broader rhythm on this creek, even if any single year can land differently.
The hero number on this page compares today’s reading with the median for this calendar day across the station record. That is more useful than a raw elevation because the same water level can mean different things in March and August.
This station has more than 75 years on record, so the calendar-day median reflects a long local history rather than a single snapshot. When you are checking whether the creek is running high for this date, or just sitting near its usual level, that comparison is the one to trust.
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.
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.
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.
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.
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.
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.
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.
