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 Sproat River near Alberni
Sproat River - A vibrant artery of South Central Vancouver Island.
The Sproat River flows near Alberni on the southern region of Vancouver Island, BC. This river is a key player in the local hydrology, contributing to the health of its watershed and offering habitat for diverse wildlife. Draining roughly 354 square kilometres above the station, it is an important part of the South Central Vancouver Island watershed, alongside peers like Ash River and Englishman River.
The watershed context
The landscape surrounding the Sproat River benefits from mountain hydrology, with water levels influenced significantly by seasonal snowmelt. Typically, freshets driven by snowpack result in peak flows from May through July, while summer months can see a natural decline due to evaporation and reduced inflow. This pattern helps to shape the ecological dynamics of the river, providing both challenges and opportunities for the species that depend on it.
The Sproat River's flowing waters support both aquatic and terrestrial ecosystems, intertwining the life cycles of fish and plants. This river is a vital resource for the region, serving anglers and local wildlife alike. Observing the fluctuations in its flow reveals much about the seasonal rhythms of the environment and highlights the interconnectedness of the region's waterways.
Why the data matters here
Monitoring the Sproat River is essential for understanding its current state and historical trends. Today's measurement, derived from the Water Survey of Canada, allows us to compare the river's current elevation against the median for this calendar day across the station's historical record—which spans 49 years. This context is crucial; it transforms raw elevation into a meaningful insight that reflects the river's health and its responses to environmental changes. Knowing how current conditions stack up against historical norms enables conservation efforts and informs users who rely on the river for various activities.
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.
