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 Yamaska – Saint-Hyacinthe
Rivière Yamaska – Saint-Hyacinthe - A vital watercourse of the Yamaska watershed.
The Rivière Yamaska, flowing through Saint-Hyacinthe in Quebec, is a significant river in the Yamaska watershed, draining roughly 3,334 square kilometers above the station. Known for its seasonal cycle influenced by the region's hydrology, this river is a key feature of the local landscape, connecting various lakes and tributaries, including Lac Brome and the Rivière Noire.
The watershed context
As part of the broader Yamaska watershed, the Rivière Yamaska plays a critical role in managing water flows within the region. It falls within a landscape characterized by a pronounced spring freshet from snowmelt between April and May, leading to seasonal peaks that can profoundly affect water levels and ecosystem health. During summer, the river sees lower water levels due to natural evaporation and reduced inflow, while early ice formation signals the onset of winter weather patterns.
The river serves not only as a dynamic aquatic ecosystem but also as a resource for local agriculture and recreational activities. Its banks provide opportunities for anglers and cottagers alike, cultivating a community closely tied to its waters.
Why the data matters here
Current measurements from the Water Survey of Canada (WSC) for the Rivière Yamaska indicate vital information about its current state. Comparing today's reading against the median for this calendar day across 32 years of historical data allows stakeholders to gauge flow conditions effectively. This data is especially relevant during seasonal transitions, where understanding water levels can inform flood assessments and ecosystem management efforts. Monitoring the river's performance through such metrics contributes to protective measures for the surrounding environment and community.
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.
