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 Hay River
Hay River - a vital waterway of the Subarctic.
Flowing near the community of Hay River in the Northwest Territories, the Hay River is a significant river known for its dynamic hydrology and ecological importance. Draining a sizable catchment area of approximately 51,400 square kilometers, it serves as a critical resource for local ecosystems and communities alike. Contributing to the Lower Hay watershed, the river also connects with other waterways such as Great Slave Lake and the Steen River, forming a network of vital aquatic habitats.
The watershed context
The Hay River exhibits distinct seasonal patterns typical of Subarctic hydrology. Spring unveils a dramatic transformation as ice begins to break up and meltwater surges through the river, often leading to ice-jam flooding. This seasonal rhythm is punctuated by long, harsh winters during which flows are significantly reduced under frozen conditions. As summer sets in, the river experiences brief yet intense flow periods driven by rain and snowmelt, although the overall volume tends to decline by late summer due to evaporation and lower inflows.
Why the data matters here
Monitoring the Hay River is essential, not only for understanding environmental and ecological changes over time but also for managing flood risks associated with the seasonal hydrology. Today's reading, when compared against the historical median for this date recorded over the last 49 years by Water Survey of Canada, provides valuable context for assessing current water conditions. Tracking changes and anomalies in river levels can aid in early warnings for communities that depend on this vital water source.
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.
