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 South Nahanni River above Virginia Falls
South Nahanni River above Virginia Falls - a river shaped by the forces of nature.
The South Nahanni River flows majestically in the Northwest Territories, Canada, just above the dramatic Virginia Falls. This section of the river is an important part of the Upper South Nahanni watershed, which contributes to the beauty and power of this remarkable waterway. With a catchment area of approximately 14,600 square kilometers, it captures the complex hydrology of the surrounding subarctic environment.
The watershed context
This expansive watershed experiences a dynamic hydrological cycle, driven primarily by the seasonal rhythms of spring breakup and snowmelt. During this time, the river swells as melting snow feeds into it, often leading to ice-jam flooding—a phenomenon not uncommon in the region. As winter retreats, long low flows precede the brief, intense summer period. The river's powerful flow is primarily supported by the waters of the winter months which accumulate under the ice, making spring runoff a critical aspect of its annual rhythm.
The South Nahanni River is an essential ecological corridor, providing habitat for various wildlife and aquatic species, while serving those who inhabit or travel through this northern landscape. Even in its rugged environment, there is a sense of life that thrives alongside the river's course.
Why the data matters here
Understanding the current river conditions at the South Nahanni River above Virginia Falls offers valuable insights for local stakeholders, including those in Indigenous communities, researchers, and outdoor enthusiasts. The station at this location measures both river level and discharge, enabling a deeper comprehension of the water's behavior throughout the year.
Today's measurement from the Water Survey of Canada provides crucial data as it compares the current level of the river against the median for this calendar day across its 44 years of historical records. By assessing water levels in this context, users gain a better understanding of how this waterway is performing relative to its typical patterns, making raw elevation figures less meaningful in isolation.
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.
