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 Stawamus River at Highway No. 99
Stawamus River - a vital watercourse in British Columbia's mountain landscape.
The Stawamus River, flowing alongside Highway No. 99 in British Columbia, is an important resource nourished by mountain hydrology. Draining roughly 52 square kilometres above the station, this river is shaped by the region's snowy winters and seasonal freshet, typically peaking from May to July as snowpack melts in the warmer months.
The watershed context
The Stawamus River belongs to the Strait of Georgia - Squamish watershed, a diverse area that includes prominent peers like the Capilano River and the Cheakamus River. These rivers contribute to the intricate web of waterways that sustain local ecosystems and serve the communities nearby. The river’s flow is primarily driven by snowmelt and rain, which is common in British Columbia's mountainous terrain, providing essential water that supports both wildlife and human activities.
Why the data matters here
At the Stawamus River gauge, current conditions are measured in terms of discharge, providing insights into the river's flow dynamics. The importance of today's reading can often be better understood against the median for this calendar day across more than 34 years of data. This allows for comparison that moves beyond raw elevation figures, offering a clearer snapshot of the river’s behavior in correlation to historical trends. For real-time data and water management insights, the station is operated by the Water Survey of Canada, providing valuable information for local cottagers, anglers, and environmental stewards.
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.
