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 Great Bear Lake
Great Bear Lake - A vast, pristine expanse of northern water.
Great Bear Lake, nestled in the heart of the Northwest Territories, is an expansive body of water known for its cold, clear depths. This lake is a significant feature of the Mackenzie Region, serving not only as a vital ecological habitat but also as an essential water resource for local communities and wildlife.
The watershed context
The Great Bear Lake watershed, encompassing a catchment area of approximately 146,000 square kilometres, plays a crucial role in the broader ecosystem. The lake itself is characterized by its subarctic hydrology, primarily influenced by seasonal dynamics. In the spring, snowmelt and breakup contribute to the lake's levels, often leading to conditions ripe for ice-jam flooding. Meanwhile, during the long winters, the lake experiences low flow under ice, marking a stark contrast to the rapid changes of summer. The summers are typically short yet intense, reflecting the northern climate’s unique rhythm.
Why the data matters here
Understanding the data from the Great Bear Lake gauge at Hornby Bay is essential for managing the water's ecological health and regional activities. The gauge provides insight into lake conditions, helping to track water levels against historical records. Currently, today's measurement can be evaluated against the median for this date over 14 years of data from the Water Survey of Canada. This comparison offers a clearer understanding of current conditions, allowing for informed decisions about local resource management and environmental monitoring. Such contextual readings beat raw elevation figures as they highlight trends and changes over time, crucial for residents and wildlife alike.
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.
