About Sharbot Lake
Sharbot Lake - a focal point of the Central Ottawa - Mississippi watershed.
Sharbot Lake, located in Frontenac County, is a significant and refreshing natural water body within the broader Central Ottawa - Mississippi watershed. This lakeside locale brings together the functions of a recreational hotspot and an important ecological resource. Draining roughly 139 square kilometres above the outlet, Sharbot Lake serves as a critical link in the regional hydrological system, providing habitat and supporting local ecosystems while also attracting cottagers and anglers alike.
The watershed context
Sharbot Lake acts as a vital connector within its watershed, surrounded by peers such as Bennett Lake and Dalhousie Lake. The waters here are shaped by the seasonal hydrology characteristic of Ontario, with snowmelt driving the spring freshet that typically occurs from late April through May. This seasonal cycle ensures that the lake experiences periodic replenishment, an essential factor in maintaining its health and vitality. During the summer months, natural drawdown takes place from July to September, contributing to the lake's characteristic seasonal ebb and flow. As colder temperatures arrive, early winter decline occurs as ice begins to form, further marking the rhythm of life here during the colder months.
Why the data matters here
Understanding the current conditions of Sharbot Lake is crucial for a wide range of local users, from cottagers managing boating and fishing activities to conservationists monitoring ecological health. The lake's hydrological data, provided by credible sources, offers a reliable measure of water elevation, which is essential for assessing both recreational potential and environmental health.
For instance, today’s reading is crucial for user planning and environmental assessments. The most current measurement against the historical median for this calendar day reveals patterns that can guide lake management and the recreational use of this natural resource. This information is collected and shared by the Water Survey of Canada, which has kept records at this station for over 23 years, providing insights that are invaluable for navigating the seasonal shifts and annual cycles of Sharbot Lake.
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 17,900+ lakes and rivers
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.
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.
Water Stories
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.
