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 Rivière Richelieu A La Marina De Saint-jean
Rivière Richelieu A La Marina De Saint-Jean - A core tributary of the Richelieu watershed.
The Rivière Richelieu A La Marina De Saint-Jean flows gracefully through the heart of Quebec, serving as a vital part of the expansive Richelieu watershed. Spanning a substantial drainage area of roughly 22,000 square kilometres, this river connects the surrounding ecosystem and community, feeding into the larger network of waterways that define the region.
Why the data matters here
Today’s readings from the Water Survey of Canada at the Rivière Richelieu A La Marina De Saint-Jean are especially notable when set against the historical median for this calendar date, derived from over 50 years of data. This benchmark provides essential context; water levels can fluctuate greatly due to seasonal changes and specific environmental factors, so understanding today's levels in relation to historical averages is crucial for effective water management and ecological assessment.
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.
