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 Lilian River near Lady Lake

Lilian River - a vital waterway in Saskatchewan's landscape.

The Lilian River flows gently near Lady Lake, nestled within the vast expanse of the Headwaters Assiniboine watershed in Saskatchewan. This river plays a crucial role in the local hydrology, serving as a vital resource for the surrounding environment and communities. With a drainage area of roughly 219 square kilometres upstream of the gauge, the Lilian River gathers waters that contribute to the health of the larger Assiniboine River system.

The watershed context

The Headwaters Assiniboine watershed is characterized by its snowmelt-dominated hydrology, particularly evident during the spring months when river flows can peak sharply. This seasonal pattern supports the ecological rhythms of the area, with significant runoff following winter snowmelt. In summer, the river typically experiences a natural recession as evaporation rates increase and inflow decreases, resulting from the area's wind-driven topography that can also affect water levels.

Nearby peers such as the Assiniboine River at Kamsack and the Assiniboine River at Sturgis highlight the interconnected nature of these waterways and their importance within the regional hydrological framework.

Why the data matters here

Data from the Lilian River gauge, operated by Water Survey of Canada, provides essential insights into the river's current health and behavior. Today's reading, compared to the median for this calendar day in the river's historical record spanning nearly 49 years, offers a critical context for understanding the effects of seasonal changes and weather patterns on the river's flow. This comparison helps local residents, farmers, and flood-watchers make informed decisions based on actual conditions rather than relying solely on raw elevation figures. The vigilance on data from the Lilian River underscores its significance in maintaining the balance of life and water in this Saskatchewan landscape.

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.
