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.

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

About Blackmud Creek near Ellerslie

Blackmud Creek - A vital flow in the Upper North Saskatchewan watershed.

Nestled in Alberta, Blackmud Creek near Ellerslie serves as an essential watercourse within the Upper North Saskatchewan - Strawberry watershed. Covering a drainage area of approximately 627 square kilometres above the station, this creek contributes to the intricate hydrological network that sustains both local ecosystems and communities.

The watershed context

Blackmud Creek is part of a broader hydrological tapestry formed by neighboring bodies such as the North Saskatchewan River at Edmonton and Whitemud Creek, both pivotal in the area's drainage system. Alberta's hydrology showcases seasonal rhythms driven by mountain snowmelt that brings late-spring peaks, while summer convective storms can lead to sudden flow increases. As these patterns unfold, Blackmud Creek plays a crucial role in managing water flow and quality, directly influencing the ecology and communities that depend on it.

Why the data matters here

Monitoring data for Blackmud Creek is invaluable, with the station actively measuring both water levels and discharge. Today's data point is significant; it helps gauge current conditions against historical averages, offering context for cottagers, anglers, and flood-watchers alike. Each reading compared to the median for this calendar day, based on over 13 years of records from Water Survey of Canada, provides insight that raw elevation figures cannot. Such benchmarks allow stakeholders to understand seasonal patterns and make informed decisions about water use and conservation efforts 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.
