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 Fraser River at Big Bar Creek
Fraser River at Big Bar Creek - A vital part of the Lower Fraser watershed.
Fraser River at Big Bar Creek is an integral stretch of the Fraser River, flowing through a basin that boasts a significant drainage area of approximately 146,000 square kilometres above the station. This section of the river plays a critical role in the broader ecological and hydrological dynamics of the Lower Fraser - Dog watershed in British Columbia.
Why the data matters here
Today's measurement of the Fraser River at Big Bar Creek, taken by the Water Survey of Canada, offers essential insights into the river’s condition. It reflects the river's response to various climatic factors, including snowmelt from the surrounding mountains, which typically influences the water levels significantly during the freshet period from May through July. Monitoring data like this not only supports recreational users such as anglers and cottagers but also aids in understanding the environmental shifts, which can impact local wildlife and overall river health.
Today's reading, compared to the median for this calendar day over the past six years, provides a clear picture of the river's current state relative to its historical trends, making it more informative than a raw elevation number alone. Understanding these fluctuations helps maintain the balance of the ecosystem and guides local water management practices.
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.
