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 Williston Lake
Williston Lake - A vast reservoir of northern beauty.
Williston Lake lies nestled in the wild expanse of British Columbia's Cassiar Land District. Stretching widely across a drainage area of approximately 72,100 square kilometres, the lake is both a significant natural feature and a vital component of the local ecology.
The watershed context
This expansive lake serves as the heart of the Northern Williston Lake watershed. While it does not have a parent river, its immense size and the surrounding terrain underscore its importance to the overall hydrology of the region. As a natural waterbody, Williston Lake plays a critical role in gathering runoff and contributing to the wider ecosystem. Here, snowmelt helps drive the seasonal freshet, which is particularly pronounced from May through July, as melting snowpack feeds the lake and surrounding landscape.
Why the data matters here
Today's readings from Water Survey of Canada gauge Williston Lake at Lost Cabin Creek provide crucial information for understanding water levels in this expansive region. By comparing today's water level to the median for this calendar day across the station's historical record, which spans over 48 years, we gain insight into both current conditions and seasonal trends. This method of assessment gives a clearer picture than simply noting raw elevation, aiding cottagers, farmers, and local resource managers in making informed decisions. Monitoring these fluctuations helps ensure the health of the ecosystem and the needs of its diverse users are met effectively.
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.
