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.

About Heart River near Nampa

Heart River - A vital waterway in Alberta's Central Peace region.

The Heart River flows near Nampa, Alberta, weaving through the stunning landscape of the Central Peace - Whitemud watershed. Covering an expansive catchment area of roughly 1,950 square kilometres, this river is an essential resource for local ecology and communities. With snowmelt from the nearby foothills driving late-spring peaks, the Heart River is influenced by the region’s seasonal patterns and weather phenomena.

The watershed context

The Central Peace - Whitemud area is characterized by its diverse hydrological patterns, where mountain snowmelt contributes to significant water flows in the spring. As summer approaches, convective storms can introduce sharp rises in water levels, showcasing the dynamic nature of the region's waterways. The Heart River serves as an essential lifeline for the surrounding environment, providing habitat and sustaining local wildlife.

Why the data matters here

Monitoring the Heart River near Nampa is vital for understanding its health and the impacts of seasonal changes. Today’s measurement reflects the river's current state compared to median levels recorded for this day over a span of 49 years, as provided by the Water Survey of Canada. This context allows for a clearer picture of hydrological patterns and trends, offering insight into both natural variability and potential impacts from climate. Having flow data is crucial not just for scientific study, but also for local stakeholders, including cottagers and farmers, who rely on this waterway for their activities.

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.
