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 Sheep River at Black Diamond

Sheep River - a vital waterway in Alberta's Highwood watershed.

The Sheep River flows through the heart of Alberta, winding its way past the town of Black Diamond. This river is an integral part of the Highwood watershed, draining roughly 591 square kilometres above the station. The Sheep River is known for its seasonal dynamics, where mountain snowmelt in late spring leads to peak water levels, while summer storms often bring sharp rises that can reshape local water conditions.

The watershed context

The Highwood watershed encompasses several significant waterways, with the Sheep River being a key contributor. Its peers include the Highwood River at Diebel's Ranch and the Sheep River at Okotoks, each contributing to the complex hydrology of the region. The interplay of mountain snowmelt and summer precipitation patterns shapes the ecological character of the watershed, influencing both water quality and aquatic habitats.

Why the data matters here

Monitoring the Sheep River at Black Diamond provides valuable insights into the river's flow and overall health. Today's river level is an important reading, particularly when compared against the median for this calendar day across the station's 13-year historical record. This comparison reveals not only current conditions but also helps identify trends and anomalies in the river's behaviour. The Water Survey of Canada operates this gauge, and such data is crucial for various stakeholders, from local farmers to outdoor enthusiasts, ensuring that they can make informed decisions based on the most accurate, up-to-date water information.

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.
