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 Koksilah River at Cowichan Station
Koksilah River - a vital waterway in Southern Vancouver Island.
The Koksilah River flows through the lush landscape of Southern Vancouver Island, offering critical hydrological support to the area and its diverse ecosystems. This river, gauged at the Cowichan Station, is part of a watershed that includes several notable peers such as the Cowichan River and Chemainus River, enriching the local environment and sustaining various flora and fauna.
The watershed context
Draining roughly 229 square kilometres above the station, the Koksilah River is an essential element of the region's hydrology. The area experiences a mountain hydrology system, characterized by freshets driven by seasonal snowpack and typically peaking between May and July. This pattern influences not only the Koksilah River but also other nearby water bodies, ensuring a consistent flow that is vital for agricultural needs and recreational activities throughout the summer months.
As a part of a dynamic watershed, the Koksilah River interacts with its surroundings in a way that creates a rich habitat for wildlife while also supporting the local community’s reliance on its water resources. Whether you’re exploring the riverbanks or casting a line, the Koksilah offers a glimpse into the thriving ecosystem of Southern Vancouver Island.
Why the data matters here
Today's reading from the Koksilah River at Cowichan Station reflects its importance in understanding local water conditions. By comparing the current measurement against the median for this calendar day over the station's historical record—which spans more than 50 years—stakeholders can gain insights into the river's health and seasonal trends. This data, collected and published by the Water Survey of Canada, is crucial for cottagers, anglers, farmers, and anyone monitoring water conditions in the area. Understanding these values helps inform decisions related to conservation, irrigation, and recreation, ensuring that this vital waterway remains a resource for generations to come.
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.
