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 River at Outlet of Great Bear Lake
Great Bear River - a vital waterway of the North.
The Great Bear River flows gracefully from the expansive Great Bear Lake, marking the beginning of its journey through Canada’s Northwest Territories. With a vast drainage area of approximately 146,000 square kilometers above the measurement station, this river plays a crucial role in the hydrology of the region. The river's importance extends into local ecosystems while serving the broader water system in the area.
The watershed context
This stretch of the Great Bear River at the outlet of Great Bear Lake reflects the dynamics of subarctic hydrology, where the impacts of seasonal changes are significant. Spring brings the thawing of ice and the rush of snowmelt, often leading to elevated flow levels and the potential for ice-jam flooding. In the winter, the river experiences low flows under a blanket of ice, as the frigid conditions limit the water's movement.
Such seasonal rhythms characterize the landscape, with short yet intense summers providing brief periods of higher flow as the ice melts and precipitation falls. As a result, the Great Bear River serves as a critical artery within this region, impacting both the surrounding environment and any communities that depend upon it.
Why the data matters here
Today, the Great Bear River reading is taken from the Water Survey of Canada’s station, demonstrating its importance in monitoring water levels. This reading is currently evaluated against the median level for this calendar day based on nearly five decades of records. Understanding how today’s measurements compare to historical levels provides essential insights into the river's behavior over time. It is not just the raw elevation that matters; such comparisons help in identifying trends, assessing flood risks, and planning for water resource management in this vital northern waterway.
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.
