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.

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 Salmo River near Salmo

Salmo River - A mountain river shaped by seasonal rhythms.

The Salmo River flows near the community of Salmo in British Columbia, traversing a landscape marked by mountain hydrology. This river draws its strength from a substantial catchment area, draining roughly 1,250 square kilometres above the station. With a history of over 50 years of monitoring, the river's health is closely observed, marking it as a vital component of the local ecosystem and water supply.

The watershed context

Situated in the Central Columbia watershed, the Salmo River is influenced by the region's seasonal patterns, primarily driven by snowmelt during the spring months. Typically, the freshet period engenders elevated flow conditions from May through July as snowpack rapidly melts, replenishing the river. This characteristic is essential, especially given the foothills and mountainous terrain that encompasses the river's route. The summer months can lead to lower flows due to evaporation and the diminishing effects of melting snow, which is a natural part of the cycle in this mountainous environment.

Why the data matters here

Recent measurements from the Salmo River gauge offer insight into its current status. Today's reading can be compared against the median for this calendar day from more than 50 years of historical data collected by the Water Survey of Canada. This context enhances the understanding of the river's health and flow dynamics, offering a more reliable picture than a simple elevation reading. Monitoring this river is crucial for local communities, agriculture, and recreational users, ensuring everyone stays informed about its changes throughout the seasons.

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.
