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 Okanagan Lake
Okanagan Lake - A central hub of the Okanagan watershed.
Nestled within the rolling hills of British Columbia, Okanagan Lake serves as a vital waterway for the region, feeding diverse ecosystems and supporting a multitude of recreational activities. Spanning a notable catchment area of approximately 5,956 square kilometres, the lake is framed by picturesque communities and serves as an important water source for agriculture, recreation, and tourism.
The watershed context
The Okanagan watershed extends into both mountainous and valley regions, benefiting from the unique mountain hydrology which drives seasonal changes in water levels. The freshet, primarily influenced by snowpack, usually peaks between May and July, sustaining lake levels throughout summer. As glacier-fed systems typically maintain higher flow rates, Okanagan Lake receives steady inflow even as the year progresses.
Several tributaries contribute to the lake's unique water character, intersecting with various creeks like Belgo Creek and Coldstream Creek, further diversifying the aquatic habitats. This network not only nurtures local wildlife but also provides ample opportunities for fishing and outdoor activities enjoyed by residents and visitors alike.
Why the data matters here
Monitoring Okanagan Lake’s water levels is essential to understand its health and function within the ecosystem. Currently, the lake's reading is compared to the historical median for this calendar day, providing crucial context for the current hydrological state. The Water Survey of Canada (WSC) manages this data and ensures its reliability. By referencing historical medians, users can better appreciate the shifts in water levels that occur with seasonal changes and respond accordingly—be it for farming, conservation, or recreational planning. Understanding these dynamics helps safeguard the lake's rich biodiversity while supporting the communities that depend on it.
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.
