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 Hay River near Alta/nwt Boundary
Hay River - a flowing lifeline of the Subarctic.
Nestled close to the boundary of the Northwest Territories, the Hay River near Alta serves as an essential waterway in the region's hydrology. This river is a significant contributor to the Lower Hay watershed, capturing the draining essence of a catchment area of approximately 48,700 square kilometres. The river plays a vital role in shaping the local ecology and provides an important source of water for nearby communities and ecosystems.
The watershed context
The Hay River flows through a landscape characterized by vast stretches of wilderness and northern terrain typical of the subarctic climate. This river is among several peers in the area, including the Great Slave Lake at Hay River and the Hay River near its own confluence further south. The seasonal rhythms here are influenced heavily by spring breakups and snowmelt events that can lead to intense periods of flow. The region experiences prolonged winter low flows under ice, followed by rapid flows in spring and early summer. During the summer months, runoff can be significant, impacting local aquatic habitats.
Why the data matters here
Understanding water levels and discharge rates at the Hay River is crucial for managing seasonal changes and potential flooding events. The Water Survey of Canada monitors these conditions, providing valuable data for local analysis. Today's reading offers a snapshot that is instrumental when compared to the historical median for this calendar day across a record of more than 37 years. This statistical approach helps gauge how current conditions align with typical seasonal cycles, proving more reliable than raw elevation data alone.
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.
