Live river level, flow, historical records and forecast for Porcupine River near International Boundary in Canada, YT, Canada, built from official government gauge data.
Porcupine River near International Boundary sits in the Central Porcupine - Coleen watershed in Yukon, Canada.
The record spans more than 38 years.
The highest level in the record is 14.94 m (49.01 ft), set in May 2011. The lowest is 6.83 m (22.42 ft), set in October 2021. Between those two extremes, the river has a typical annual swing of 3.21 m (10.5 ft).
The seasonal pattern is clear: the usual high point comes in May at 10.33 m (33.89 ft), and the usual low point comes in February at 7.12 m (23.36 ft). For a dock, intake, or bank access, that range is the part to plan around.
The fastest 24-hour rise on record was 2.99 m (9.8 ft) in May 2017. The fastest 24-hour drop was 1.33 m (4.4 ft) in May 2022. Those are the kinds of changes that can shorten warning time for anyone watching water levels closely.
The station drains 58900 km2 (22741 sq mi) above the gauge. That is the area upstream of this site, not the full watershed name on the page.
This is a Yukon river reach in a subarctic mountain setting, so the seasonal note fits the record: snowmelt drives the May-July peak, and winter lows are the quiet part of the year. The highest month here is May, which is the month to watch for higher water and faster changes at the bank.
The hero number on this page should be read against the median for this calendar day at station 09FD002, not as a raw elevation by itself. A level that is near the median for this date means conditions are close to the station’s usual pattern for this day; a level far above or below that median tells you more about today’s runoff signal.
At a Canadian station like this one, the operating agency is Water Survey of Canada. With more than 38 years on record, the daily median is the better local reference for anglers, cottagers, and flood-watchers than a single fixed threshold.
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 in a growing number of countries. Built on official government data.
Nibi Metrics tracks more than 17,900 gauged lakes and rivers in a growing number of countries, reading directly from official federal monitoring networks: the Water Survey of Canada, the United States Geological Survey, Quebec's provincial hydrometric network, the Environment Agency for England, the Scottish Environment Protection Agency, Natural Resources Wales, the Office of Public Works in Ireland (waterlevel.ie), the Norwegian Water Resources and Energy Directorate (NVE), the State of Queensland's water monitoring network, and on the Great Lakes the Canadian Hydrographic Service and NOAA. 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.
Field notes and explainers from the Nibi desk - how to read a staff gauge, what a 100-year flood actually means, how snowpack becomes summer water.
The largest lake in Norway read under 8 metres for decades and reads over 120 today. The water did not move; the ruler did. What the zero of a gauge is, why a record only means something on one reference, and what we do when the zero moves.
There was no rain. A slab of glacier let go above the Trishuli, and a river gauge reading normal at 8:40 was silent by 8:50. What a river network can see coming, what it cannot, and what warning has to look like when the water outruns the news.
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.
