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 Fraser River near Agassiz

Fraser River near Agassiz - a vital artery for the Lower Fraser watershed.

The Fraser River near Agassiz flows through the stunning landscapes of British Columbia, functioning as a crucial waterway in the Lower Fraser - Nahatlatch watershed. This section of the river is part of an expansive drainage area of roughly 218,000 square kilometres, which is vital for the ecological health and economic activities in the region. The Fraser River is known for its significant flow, particularly influenced by the mountain hydrology typical of British Columbia, with freshets driven by seasonal snowpack that often peak from May through July.

The watershed context

The Lower Fraser watershed is a diverse and dynamic ecosystem, with the Fraser River running adjacent to several other waterways including the Coquihalla River and multiple tributaries that feed into its grand flow. This vibrant watershed supports a rich variety of plant and animal life, contributing to the natural heritage of the region. The river's flow dynamics are crucial for keeping the ecosystem balanced, particularly during the freshet period when water levels ride high due to melting snowpack.

Why the data matters here

The water level readings from the Fraser River near Agassiz are monitored consistently, providing vital data to understand its current status and potential risks for flooding or low flow periods. As reported by the Water Survey of Canada, today's reading serves as a benchmark against the median for this calendar day across nearly 50 years of historical data. This comparative approach adds depth to the analysis, offering insights that raw elevation measurements cannot provide, and thus is crucial for the cottagers, fishermen, and local communities that rely on this rich, flowing resource.

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.
