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 Similkameen River at Princeton
Similkameen River - An essential waterway of the Similkameen Valley.
The Similkameen River at Princeton serves as a vital water resource flowing through British Columbia's scenic landscape. Draining approximately 1,810 square kilometres, the river plays a crucial role in the region’s ecology and hydrology.
The watershed context
The Similkameen River, nestled within its namesake watershed, is shaped by mountain hydrology typical of the region, with runoff largely influenced by snowmelt. The freshet period, which peaks from May to July, is particularly significant as it brings high water levels, replenishing the river system after winter’s snowpack has melted. This seasonal rhythm not only sustains aquatic ecosystems but also supports agricultural activities in the surrounding valley.
Why the data matters here
Today's river reading at Princeton provides insight into water conditions affecting both ecology and human activity. Measuring discharge, this station has been monitoring flows for nearly 49 years, delivering critical data to inform local usage and environmental health. Comparing today's measurement against the median for this calendar day enriches our understanding of how current conditions align with historical patterns, a more nuanced approach than evaluating raw elevation alone. The Water Survey of Canada operates this gauge, ensuring that the data reflects both natural variability and potential changes over time.
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.
