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 at Tenas Narrows
Lillooet River - A testament to mountain-fed vitality.
The Lillooet River at Tenas Narrows showcases the dynamic interplay of mountain hydrology and river systems typical in British Columbia. Stretching through a significant drainage area of roughly 4,480 square kilometres, this section of the river is shaped by the high peaks that dominate the landscape, ultimately informing its flow patterns.
The watershed context
The Lillooet River flows through the Harrison watershed, an area characterized by its rugged terrain and glacial influences. This river, alongside its peers such as the Chehalis River and Harrison River, plays a critical role in supporting the surrounding ecology. The seasonal changes in the region are driven largely by snowmelt, which leads to peak flows between May and July. As the snowpack gradually melts, the river experiences substantial increases in discharge, nourishing the diverse plant and animal life that thrives in these ecosystems.
Why the data matters here
Monitoring the Lillooet River is vital not only for understanding its current state but for anticipating seasonal changes that could impact local communities and ecosystems. Current readings from the Water Survey of Canada reveal conditions in relation to historical data, giving context to today's measurements. Presently, today's water level, when compared to the median for this calendar day over the past 13 years, offers a more comprehensive perspective than the elevation alone. This approach helps both local residents and stakeholders navigate the potential impacts of fluctuating water levels, particularly during a year well within the established seasonal rhythms of mountain-fed systems.
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.
