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 Harrison Lake
Harrison Lake - A key reservoir in British Columbia's mountain landscapes.
Harrison Lake is a significant body of water located in the New Westminster Land District of British Columbia. This large lake serves as both a natural resource and a thriving ecosystem, nestled in a region where the mountain hydrology plays a pivotal role in shaping local water systems. With a substantial drainage area of approximately 7,870 square kilometers above the lake, Harrison Lake is linked to various waterways, including the notable Harrison River and nearby Lillooet Lake.
The watershed context
The Harrison watershed encompasses a diverse array of ecosystems, influenced heavily by the seasonal rhythms typical of British Columbia's mountainous terrain. In this region, the freshet—driven by melting snowpack—commonly peaks from May to July. This annual cycle contributes to the high water levels seen in Harrison Lake during spring and early summer. Various peers of Harrison Lake, such as the Chehalis River and Harrison River, reflect similar hydrological patterns, each playing its role in maintaining the ecological balance and supporting local wildlife.
Why the data matters here
Monitoring water levels at Harrison Lake is crucial for understanding both the immediate hydrological dynamics and the broader implications of climate variability. The data from the monitoring station, "Harrison Lake near Harrison Hot Springs," provides real-time insights into lake levels, which can inform local residents, cottagers, and visitors. As the Water Survey of Canada has tracked the lake for over 14 years, comparing today's reading to the median for this calendar day allows users to see where current conditions stand in relation to historical patterns, offering a clearer picture than raw elevation alone. It is vital for those who depend on Harrison Lake for recreational activities or natural resource management to stay informed about the ongoing changes in water levels.
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.
