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 Riviere Des Outaouais A Hull

Riviere Des Outaouais A Hull - A vital flow in the Rideau watershed.

The Riviere Des Outaouais A Hull is a significant waterway, part of the extensive Rideau watershed in Quebec. It plays an important role in the regional hydrology, shaped by the natural rhythms of spring freshet and seasonal ice formation.

Why the data matters here

Understanding the water levels of the Riviere Des Outaouais A Hull is essential for various activities ranging from recreational use to environmental monitoring. Today’s reading provides valuable insights within the historical context, measured against 49 years of data collected. This gauge serves not only as a marker for current conditions but also as a benchmark for comparison to the median for this calendar day, which enhances our understanding of the river’s seasonal behavior.

Monitoring the river’s status is crucial, especially during the spring months, when snowmelt contributes to strong freshet conditions that can significantly increase water levels. As summer approaches, water levels typically decline due to evaporation, and early ice formation begins in the colder months, marking a cyclic cadence of the watershed’s dynamics.

The data collected by the Water Survey of Canada offers a reliable look into the river's health and assists in predicting changes that may affect local ecosystems and water users. Comparing current levels to historical medians allows stakeholders to assess whether today's conditions deviate from expected patterns, informing water management strategies and conservation efforts.

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.
