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.

Water Stories

The flood of record that was overtaken

For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.

Why the Assiniboine floods every spring

Inside the freshet cycle that puts Manitoba shorelines at risk each year - and why 2026 broke the script.

About Assiniboine River near Miniota

Assiniboine River near Miniota - a vital flow through the heart of Manitoba.

The Assiniboine River near Miniota is a key watercourse in Manitoba, traversing through an expansive landscape that supports both ecological diversity and human activity. Located within the Upper Assiniboine - Birdtail watershed, this section of the river plays an important role in the regional hydrology typical of Prairie environments. As snowmelt swells the river in spring, it sets the stage for seasonal fluctuations that are crucial for both agriculture and biodiversity.

The watershed context

With a significant drainage area of approximately 75,200 square kilometres, the Assiniboine River collects runoff from a broad region. It flows through an area characterized by agricultural land, which often relies on the health of the river system. Neighboring water bodies include the Assiniboine River Southwest of St. Lazare and the Assiniboine River near Russell, each contributing to the larger basin's dynamics. The seasonal rhythm in Manitoba generally sees peak flows during the spring thaw, followed by a summer recession. This natural cycle is essential for maintaining the ecological balance of the river and surrounding areas.

Why the data matters here

Monitoring at the Assiniboine River near Miniota includes both water levels and discharge, providing vital data for managing water resources and understanding flood risks. Today's reading is crucial as it offers insight into the current conditions relative to historical data, specifically comparing today's level against the median for this calendar day over the last 48 years. This approach, employed by the Water Survey of Canada, not only helps gauge current hydrological circumstances but also informs predictions and preparations for potential flood events in the future, underscoring the importance of reliable data for local communities and stakeholders.

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.
