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 Garry River near Alexandria
Garry River - A flowing connection in Ontario's Upper St. Lawrence region.
The Garry River winds its way near Alexandria, Ontario, offering a vital watercourse in the Upper St. Lawrence - Raisin watershed. As a tributary, it drains approximately 30.4 square kilometres above the gauge, contributing to the complex hydrological network that supports both local ecology and community needs.
Why the data matters here
Understanding the Garry River’s current conditions is essential for monitoring changes in its flow patterns, especially given the snowmelt-driven seasonal rhythm typical of Ontario. The spring freshet between late April and May brings increased flow rates, while the river naturally experiences drawdown during the summer months from July to September, as evaporation takes its toll and inflows diminish. Additionally, early winter typically sees water levels decline further as ice begins to form.
Data from the Garry River gauge is critical for residents, anglers, and land managers who depend on accurate and timely information about water conditions. The readings provide insights into both immediate safety concerns, such as potential flooding, and long-term trends that can affect ecosystem health and water quality.
Today's measurement, when compared against the historical median for this date over more than 20 years of records maintained by Water Survey of Canada, offers a comprehensive view of how today’s conditions measure up, thus helping gauge the overall health of the Garry River in real-time.
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.
