About Baker Creek at Outlet of Lower Martin Lake
Baker Creek at Outlet of Lower Martin Lake is a gauged river in the Yellowknife watershed, Northwest Territories.
Season by season
The usual rise comes in June, when levels sit near 29.41 m (96.48 ft). By October, the typical level is 29.13 m (95.58 ft). That is a seasonal swing of 27.3 cm (10.7 in), which is small on paper but still enough to matter for a dock, a crossing, or an intake set close to the waterline.
The station drains 144 km2 (55.4 sq mi) upstream of the gauge. In a subarctic setting, that upstream area tends to send its biggest signal during spring breakup and snowmelt, while winter can hold the river down under ice. For someone using this water, the main point is timing: the move from winter low flow to spring rise can be fast, and summer water can settle back after the melt pulse passes.
Records and rises
The record high is 29.91 m (98.12 ft), set in May 2006. The record low is 28.87 m (94.72 ft), set in October 2023. Those two marks show the reach has already moved through more than a metre of range at this gauge, even though the usual annual swing is much smaller.
That is the kind of history anglers and cottagers should keep in mind when judging bank exposure, boat access, and where gear sits through the year. The highest month is June, but the all-time peak arrived in May, so the seasonal pattern is not the whole story. The river can still push higher when the right conditions line up in spring.
This station has 42 years on record, which gives the local range some depth. It means the usual levels here are not a guess from one season, but a long station history that captures both ordinary months and the outliers.
Reading the hero number
The hero number on this page compares today’s reading with the median for this calendar day across more than 42 years on record. That is more useful than raw elevation because a level only tells you where the water sits today; the median tells you whether today is ordinary for this date at this station.
For a place like Baker Creek, that difference matters. A late-June reading can be judged against other late-June readings, not against a number taken in October or during the spring rise. That gives a clearer read on how much room a shoreline, crossing, or intake has left right now.
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.
