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 Lac Memphrémagog
Lac Memphrémagog - A vital waterway in the Upper Saint-François watershed.
Lac Memphrémagog serves as a significant freshwater body in the province of Quebec, known for its expansive catchment area of approximately 1,780 square kilometers. Nestled within the Upper Saint-François watershed, it provides essential habitat for local wildlife and influences the water dynamics in the region. It is also joined by its peer, Lac Aylmer, adding to the interconnectedness of the local hydrology.
Why the data matters here
Understanding the water levels in Lac Memphrémagog is crucial, particularly given the region's strong spring freshet from April to May driven by snowmelt. These seasonal patterns influence water availability and ecosystem health, especially as summer water levels tend to decline due to natural evaporation. The reading at the gauge, Memphremagog (Lac) A Magog, reflects these changing dynamics and is crucial for local stakeholders, including cottagers and anglers, who rely on water levels for their activities.
Today’s reading is viewed in the context of the median for this calendar day, derived from over 50 years of historical data provided by Water Survey of Canada. This allows for a meaningful assessment of current conditions and helps gauge how today’s level stands in relation to typical patterns, offering insights that raw elevation figures alone cannot provide.
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.
