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.

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 Nimpkish River above Woss River

Nimpkish River - a dynamic river shaped by seasonal flows.

The Nimpkish River above Woss River flows through the Northeastern Vancouver Island region of British Columbia, serving as a crucial artery in the local hydrology. Draining roughly 774 square kilometres above the station, this river is fed by the diverse rainfall and snowfall patterns typical of the mountains surrounding it. The river experiences seasonal fluctuations, peaking during the freshet season from May to July when snowmelt significantly increases its flow.

The watershed context

This section of the Nimpkish River showcases a complex interplay with neighboring waterways such as the Eve River, Keogh River, and Pugh Creek, which share the Northeastern Vancouver Island watershed. This area is characterized by mountain hydrology, where the snowpack contributes to the river's flow, and variations in seasonal precipitation patterns dictate the river's behavior throughout the year. As the summer months approach, evaporation and lower inflow can lead to natural declines in water levels.

The mountain-fed waterways create a dynamic ecosystem, supporting both flora and fauna along their banks while also providing essential resources for local communities engaged in agriculture and recreation.

Why the data matters here

Monitoring water levels at the Nimpkish River above Woss River is essential for understanding the river's current conditions, which thrive under the influences of regional hydrology. Today's reading is especially relevant, as it reflects how the current level compares against the median for this calendar day over the past 35 years. This context becomes increasingly valuable over time, as it reveals long-term trends and day-to-day variations. By analyzing the data provided by the Water Survey of Canada, stakeholders can gain insights into river health, flood risks, and the broader ecological impacts on the region's watershed, ultimately supporting informed decision-making for both conservation and community needs.

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.
