Nibi Metrics
Real-time water levels, forecasts, and alerts for lakes and rivers across Canada and the US. Built on official government data.
Nibi Metrics turns raw gauge readings from official hydrometric networks into something a person standing on a dock can actually use: is the water high or low for today, which way is it moving, and how unusual is this? This page explains where every number on the platform comes from and what we do to it along the way.

About Riviere Des Mille Iles A Bois-des-filion
Riviere Des Mille Iles A Bois-des-Filion - A significant tributary in the St. Lawrence watershed.
Flowing gently through the province of Quebec, the Riviere Des Mille Iles at Bois-des-Filion is a vital waterway contributing to the expansive St. Lawrence River system. This river, which drains an impressive catchment area of 147,000 square kilometres upstream of its monitoring station, supports a rich blend of natural features and human activities.
The watershed context
As part of the St. Lawrence River watershed, the Riviere Des Mille Iles plays a crucial role in the region’s hydrology and ecology. The river connects with various significant peers, such as Lac Saint-Louis and the Outaouais River, providing a network of waterways that enhance the area's biodiversity. Typically, the region experiences a strong spring freshet from April to May, when the snowmelt contributes to elevated water levels, followed by a natural decline through the summer months due to low inflow and evaporation.
Why the data matters here
Water levels are essential for understanding the health of the river and its surrounding ecosystems. Currently, as measured by the Water Survey of Canada, today's reading provides a snapshot in time against the median for this calendar day across the station's 50 years of record-keeping. This data not only helps monitor the river's current state but also aids in assessing long-term trends. Such comparisons underscore the importance of consistent water monitoring, enabling local communities, farmers, and fisheries to better manage their interactions with the river and its resources.
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.
