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.

About Peace River below Chenal Des Quatre Fourches

Peace River below Chenal Des Quatre Fourches - A flowing artery of the Upper Slave watershed.

The Peace River below Chenal Des Quatre Fourches is a vital segment of the Upper Slave watershed in Alberta. This stretch of river showcases the dynamic hydrology characteristic of its region, shaped by seasonal factors that influence water levels throughout the year.

## The water and the watershed The Peace River here drains a substantial area of approximately 323,000 square kilometers. This wide catchment area means that the river experiences significant variation in flow, driven primarily by late-spring mountain snowmelt and summer convective storms. As snow accumulates in the mountains through winter and melts in late spring, it fuels robust flows in the river, making this an essential time for both natural ecosystems and human activities reliant on the water. During the summer months, sporadic storms can lead to sharp rises in water levels, highlighting the river's responsive nature to climatic conditions.

## Why the data matters here Water levels on the Peace River below Chenal Des Quatre Fourches are reported in absolute terms, providing a snapshot of current conditions that are crucial for local stakeholders, including farmers, fishers, and flood-watchers. Today's reading can be compared against the median for this calendar day across 49 years of data collected by the Water Survey of Canada. This context allows for better understanding of the river's behavior over seasons, contributing to informed decision-making for those who depend on its water resources.

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.
