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.

About Chemainus River near Westholme
Chemainus River - A dynamic artery through Southern Vancouver Island.
Flowing gracefully through the heart of Southern Vancouver Island, the Chemainus River near Westholme is a notable freshwater resource with a catchment area of approximately 351 square kilometres. This river supports a diverse array of flora and fauna while serving as an important waterway for local communities and ecosystems alike.
The watershed context
The Chemainus River is part of the larger Southern Vancouver Island watershed, which includes several noteworthy peers such as the Bings Creek, Cottonwood Creek, and the Cowichan River. This region experiences a mountain hydrology, where the seasonal rhythm is influenced by snowmelt, particularly peaking between May and July. This freshet provides crucial water flow that sustains not only the river but also the surrounding ecosystems that rely on its waters throughout the year.
Why the data matters here
Understanding the river's dynamics is essential to managing its health and the ecosystems it supports. Data from the Chemainus River near Westholme station helps monitor water levels, providing insights into current conditions compared to historical records. Assessing today’s readings against the median for this calendar day helps gauge whether the river's flow is typical for this time of year, which is an important aspect of understanding its overall health. This data is essential for various stakeholders, including cottagers, anglers, and farmers who depend on reliable water levels for their activities. The Water Survey of Canada operates this station, which has been recording data for the past 50 years, thus facilitating informed decisions for the conservation and management of 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.
