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.

Why the Assiniboine floods every spring

Inside the freshet cycle that puts Manitoba shorelines at risk each year - and why 2026 broke the script.

Flash Flood Alley: how Texas rivers rise in hours

Why Central and South Texas rivers go from gravel beds to fifty-year records in an afternoon - including July 2026 on the Nueces.

About Assiniboine River at Sturgis

Assiniboine River at Sturgis - a key contributor to the Headwaters Assiniboine watershed.

The Assiniboine River flows gracefully through Saskatchewan, with the Sturgis gauge serving as an important point for monitoring its waters. This stretch of the river plays a vital role in the larger Headwaters Assiniboine watershed, which encompasses a diverse landscape that supports a wide array of wildlife and agricultural activities. The river’s flow is influenced by the seasonal patterns typical of prairie hydrology, characterized by a sharp peak during snowmelt in spring, followed by a lengthy summer recession.

The watershed context

Draining an area of roughly 1,910 square kilometres, the Assiniboine River at Sturgis interacts with several neighboring waterways, such as the Assiniboine River at Kamsack and the Lilian River near Lady Lake. Seasonal dynamics significantly impact water levels here, with the early spring thaw contributing to pronounced fluctuations in flow. As the summer months approach, evaporation and reduced inflow lead to natural declines, echoing the broader trends of prairie water systems.

Why the data matters here

Monitoring data from this station not only provides insight into the river’s current conditions but also aids in understanding the hydrological patterns that affect the ecosystem and surrounding farmland. Today's reading is crucial as it allows for comparison against the historical median for this date over 49 years of records collected by Water Survey of Canada. This context offers a more comprehensive understanding of water conditions than raw elevation alone, allowing cottagers, farmers, and local stakeholders to make informed decisions around water use and management.

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.
