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 Quinsam River below Lower Quinsam Lake

Quinsam River below Lower Quinsam Lake - A vital flow in East Central Vancouver Island.

The Quinsam River flows gracefully below Lower Quinsam Lake, meandering through the rich landscapes of East Central Vancouver Island in British Columbia. This river, stretching through an area that supports both biodiversity and human activity, offers an essential connection between the lake and the greater watershed. Fed by the melting snowpack in spring, the river exhibits seasonal fluctuations and plays an important role in the local hydrology.

The watershed context

The Quinsam River is part of a larger hydrological network that includes several notable peers, such as Buttle Lake, Campbell River, and the Elk River. The watershed drains an extensive 221 square kilometers, gathering runoff from the surrounding terrain and driving the river's flow. This area experiences a freshet driven by seasonal snowpack, typically peaking from May to July. As the snow begins to melt in the warmer months, streams and rivers swell, providing critical water flow for ecosystems and recreational activities alike.

Why the data matters here

In hydrology, data accuracy is crucial for assessing water conditions. The monitoring station for the Quinsam River, overseen by Water Survey of Canada, helps track both water levels and discharge, contributing to a better understanding of water availability and quality in the region. Today's reading offers valuable insight when compared to the median for this calendar day, calculated from 28 years of historical data. While the raw elevation of the river provides information about its current state, comparing it against historical medians gives a clearer picture of how flows are changing over time, reflecting on the impact of seasonal variability on this vital waterway.

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.
