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 Porcupine River near International Boundary

Porcupine River - a vital waterway at the international boundary.

The Porcupine River flows near the International Boundary in the Yukon Territory, serving as a significant channel in the Central Porcupine - Coleen watershed. With an extensive drainage area extending over approximately 58,900 square kilometers, this river plays a crucial role in managing the regional hydrology.

The watershed context

This river is part of a broader hydrological network that includes notable peers, such as the Porcupine River below Old Crow River. The watershed offers a diverse range of aquatic environments, shaped by seasonal fluctuations. The Subarctic mountain hydrology characteristic of this region means that peak flows generally occur between May and July, driven primarily by melting snow. This seasonal pattern has profound implications for the local ecosystem and water management strategies.

Why the data matters here

Current water levels in the Porcupine River are essential for understanding the ongoing environmental conditions and potential impacts of the seasonal rhythms. Today's reading should be evaluated against the historical median for this date, providing valuable context for what is typical at this time of year. Monitoring agencies like the Water Survey of Canada contribute vital data to help gauge these changes, informing local communities and stakeholders about river conditions over the 38 years of available records.

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.
