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.

Saskatchewan River below Tobin Lake Water Level

Live river level, flow, historical records and forecast for Saskatchewan River below Tobin Lake in Canada, SK, Canada, built from official government gauge data.

About Saskatchewan River below Tobin Lake

Saskatchewan River below Tobin Lake - A vital stretch of the Upper Saskatchewan.

The Saskatchewan River below Tobin Lake is a significant reach in the Upper Saskatchewan watershed, highlighting the dynamic interplay of snowmelt and seasonal changes in this region of Saskatchewan. Draining an expansive area of approximately 276,000 square kilometres above the station, this river course plays an essential role in the hydrology and ecology of the landscape.

The watershed context

The Upper Saskatchewan watershed is characterized by its diverse terrain and water flow influenced heavily by seasonal patterns. In spring, snowmelt drives peak flows, often resulting in more pronounced and rapid elevations in water levels. Following this spring peak, the river experiences long summer recessions, where water levels typically drop as inflow decreases due to evaporation and lower precipitation. Neighboring Tobin Lake is a critical feature to note, acting as a natural regulator of water flow, contributing to the overall health of the Saskatchewan River below.

Why the data matters here

Monitoring the Saskatchewan River below Tobin Lake provides essential insights into the river's hydrological patterns, particularly during its spring melt and summer recessions. Today’s reading offers a snapshot of the current water conditions compared to the median for this calendar day across the station's historical record, which spans more than 49 years. This comparison aids in understanding the river's natural fluctuations and ensures effective management practices for local stakeholders. By referencing the data provided by Water Survey of Canada, communities can better prepare for the natural variations in water levels that affect both ecological and human activities in the region.

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.
