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 Oldman River near Brocket

Oldman River near Brocket - A vital artery in Alberta's Upper Oldman watershed.

The Oldman River flows near Brocket, an essential feature of Alberta's landscape, cradled within the Upper Oldman watershed. This river is known for its dynamic response to the seasonal changes typical of the foothills and prairie hydrology. Late spring often sees peaks driven by the melting mountain snowpack, while summer convective storms can lead to rapid increases in flow, bringing life to the surrounding ecosystems and communities.

The watershed context

The Oldman River watershed spans an impressive 4,410 square kilometres. It shares its landscape with notable peers like the Castle River and Crowsnest River, which also find their way through Alberta's diverse terrain. The hydrology here is heavily influenced by the mountainous regions that feed the river system, ensuring a vibrant flow during the critical melt season. As the snow starts to thaw and the summer rains roll in, the Oldman River near Brocket showcases the natural rhythms of water movement in this region.

Why the data matters here

Today's reading from the Oldman River near Brocket can be systematically compared against the median for this calendar day over the past 49 years, as monitored by the Water Survey of Canada. This comparative insight is crucial, as it provides context on whether the river's current flow is typical, high, or low for this time of year. While raw elevation figures offer a snapshot, understanding the data in relation to historical trends offers a richer picture of the river's health and responsiveness to seasonal changes.

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.
