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 Outaouais (riviere Des) A Terrasse-vaudreuil
Outaouais River - A vital tributary within the St. Lawrence watershed.
The Outaouais River, specifically at Terrasse-Vaudreuil, is a significant waterway that contributes to the broader St. Lawrence River system. With a substantial drainage area of approximately 147,000 square kilometers above this station, it plays an important role in the hydrology of the region. The Outaouais River is well-positioned among its local peers, which include Lac Saint-Louis and several other tributaries that enhance the ecological richness of this area.
The watershed context
The St. Lawrence River watershed, which the Outaouais River feeds into, is a dynamic ecological network characterized by seasonal cycles of snowmelt, which typically create a strong spring freshet between April and May. This natural rhythm influences the water levels and flow patterns of the Outaouais, leading to fluctuating conditions throughout the year. The summer months often see lower water levels due to evaporation and decreased inflows, while ice formation begins early in the fall, preparing the river for winter's freeze.
Why the data matters here
Monitoring the Outaouais River at Terrasse-Vaudreuil is essential for understanding local hydrological trends and ensuring the health of the ecosystem. The gauge measures discharge, providing insights into the river's flow and its relationship to historical data. Currently, the water level readings can be compared against the median for this calendar day based on the station's historical record spanning more than 16 years. This detailed perspective, provided by the Water Survey of Canada, allows for better water management and awareness for all who rely on or interact with this vital waterway. Measurement against the median helps to contextualize today's readings, offering a clearer picture of current water conditions rather than relying solely on raw elevation figures.
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.
