Clyde River near Lanark Water Level

Live river level, flow, historical records and forecast for Clyde River near Lanark in ON, Canada, built from official government gauge data.

About Clyde River near Lanark

Clyde River near Lanark is in the Central Ottawa - Mississippi watershed in Ontario.

The watershed

The station drains 617 km2 (238 sq mi) above the gauge. That is the area feeding this reading, not the whole watershed.

For people using the river near Lanark, that upstream area matters because it sets how much water can reach the gauge during wet periods and how quickly the level can settle in dry ones. The record here spans more than 55 years, so the range below is worth paying attention to.

What the numbers say

The record high is 10.88 m (35.69 ft) in April 2019. The record low is 7.62 m (25.01 ft) in August 2016. That gap is the range this station has seen on the river.

Seasonally, the highest typical month is April at 8.97 m (29.43 ft), and the lowest typical month is September at 7.88 m (25.84 ft). The typical annual swing is 1.1 m (3.6 ft). For a dock, bank access, or a shallow intake, that swing is the part to plan around.

The regional pattern here is spring freshet late April-May, natural summer drawdown July-September, and early-winter decline as ice forms. The monthly pattern at this station fits that rhythm: the river is typically higher in April and lower in September.

Reading the hero number

The hero number on this page is the current level set beside the median for this calendar day across the station record. That is more useful than raw elevation alone because it tells you whether today sits high or low for this date, not just what the gauge reads in metres.

With more than 55 years on record, Water Survey of Canada gives that comparison enough history to matter for cottagers, anglers, and anyone watching access or flooding conditions.

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

For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.
