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 Lake
Lillooet Lake - A glacially fed gem amidst mountain ranges.
Lillooet Lake lies nestled in the stunning expanse of British Columbia's mountains, offering breathtaking views and a vital ecological resource. As part of the Harrison watershed, this lake is a significant component of the region's hydrology, supported by a substantial drainage area of approximately 4,440 square kilometres.
The watershed context
The Harrison watershed encompasses a rich tapestry of waterways that flow through the mountainous terrains of Lillooet Land District. Lillooet Lake connects with other regional peers, such as the Harrison River, Harrison Lake, and Lillooet River, forming an integral part of the greater hydrological network. These bodies of water reflect the characteristics of mountain hydrology, with seasonal patterns dictated primarily by winter snowpack and the subsequent spring freshet. Typically, water levels in the region peak from May to July, as melting snow from nearby ranges contributes significantly to water inflow.
Why the data matters here
Monitoring the water levels at Lillooet Lake is crucial for understanding the dynamics within its ecosystem and the health of the surrounding environment. With 49 years of historical data collected by Water Survey of Canada, the current readings are examined against the median for this day across all recorded years. This metric provides a clearer perspective on the lake's seasonal behavior, helping to gauge fluctuations caused by natural factors such as evaporation or melted snow contributing to the freshet.
This lake is not only a breathtaking feature of the landscape but also a vital component in the larger ecological system. Observing its water levels ensures that local stakeholders, including anglers and cottagers, remain informed about the lake's changing conditions and the implications on local flora and fauna.
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.
