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.

About Last Mountain Lake
Last Mountain Lake - A significant water body within the Last Mountain watershed.
Last Mountain Lake, located in Saskatchewan, is a prominent feature of the Last Mountain watershed, extending across an area of approximately 14,400 square kilometers. This lake plays a vital role in the local hydrology, providing essential water resources to the region and supporting the surrounding environment.
The watershed context
The Last Mountain watershed is characterized by its snowmelt-dominated hydrology, typical of the Prairie region. Spring usually sees a sharp peak in water levels, driven primarily by melting snow, which can lead to significant inflows into the lake. Following this peak, the summer months generally bring a prolonged recession in water levels as evaporation takes its toll, and inflows diminish. These seasonal patterns shape the dynamics of Last Mountain Lake, influencing its ecology and the activities of those who rely on its waters.
Why the data matters here
Today's readings from the gauge at Last Mountain Lake, registered by Water Survey of Canada, provide essential insights into the lake's current conditions. It is important to compare today's elevation against the median for this calendar day from the station's historical record of over 50 years. This context offers a clearer understanding of the water level's significance, aiding cottagers, fishermen, and anyone monitoring the lake's behavior. Such comparisons are crucial, as they reflect not only the present conditions but also help indicate trends that may impact the local environment and recreational 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.
