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 Lillooet River near Pemberton
Lillooet River - A dynamic flow from mountain sources.
Nestled as a vital waterway in British Columbia, the Lillooet River near Pemberton originates from the stunning mountain landscapes that define the region. This river is part of the Harrison watershed, contributing to a larger hydrological system that supports both ecology and human activities in the surrounding areas.
The watershed context
With a drainage area of approximately 2,080 square kilometres, the Lillooet River flows through a rugged terrain influenced by both alpine snowpack and glacial melt. This mountain hydrology dictates a seasonal rhythm where the freshet, or spring thaw driven by melting snow, typically peaks from May to July. During the summer months, the river remains elevated due to glacial influences which help sustain flows despite evaporation. Nearby rivers, including the Chehalis River and Fitzsimmons Creek, showcase the interconnectedness of the regional hydrology and reflect the natural patterns of water movement in this mountainous landscape.
Why the data matters here
Water levels and flow dynamics are essential for understanding the Lillooet River's health and the ecosystems it supports. The river is equipped with a monitoring station, which provides valuable data. Regular readings enable local stakeholders, from farmers to anglers, to make informed decisions based on comparative analysis against historical medians.
Today's reading is particularly relevant—by comparing the current flow level to the median for this calendar day across nearly five decades of data provided by Water Survey of Canada, we gain insight into how this vital body of water is performing relative to its historical averages. Each reading not only informs us about the river’s status but also enables a deeper understanding of the regional hydrology that influences our lives and environment.
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.
