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 Brome
Lac Brome - A central feature of the Yamaska watershed.
Lac Brome, located in the picturesque region of Lac-Brome in Quebec, stands as a critical freshwater resource within the Yamaska watershed. Covering an area of approximately 184 square kilometres upstream of the monitoring station, this lake plays a vital role in the local ecosystem and water management.
The watershed context
Lac Brome is flanked by other water bodies such as Rivière Noire and Rivière Yamaska, which highlight its significance within the hydrological network of the Brome-Missisquoi region. The area experiences a strong spring freshet from April to May, thanks to the melting snow, followed by summer months typically marked by lower water levels due to evaporation and reduced inflows. As winter approaches, early ice formation is common, shaping the recreational activities around the lake and influencing local wildlife patterns.
Why the data matters here
Today's reading at Lac Brome is compared against the median for this calendar day across 21 years of historical data provided by the Centre d'expertise hydro-québécois (CEHQ). This form of comparison allows stakeholders, from cottagers to environmental researchers, to gauge the lake's current state in context to its historical patterns. Understanding these fluctuations is essential for managing water quality and ecosystem health, as well as anticipating how seasonal rhythms might affect recreational use and aquatic habitat.
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.
