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 Kootenay Lake
Kootenay Lake - A prominent feature in the Kootenay Land District.
Kootenay Lake, nestled in the beautiful landscape of British Columbia, is a significant water body in the region, spanning a vast catchment of approximately 45,500 square kilometres upstream of the Kootenay Lake at Queens Bay gauging station. This lake is an essential component of the Lower Kootenay watershed, which plays a vital role in the local ecosystem and hydrology.
## The watershed context The hydrology in this area is heavily influenced by the mountainous terrain, leading to a freshet that is primarily driven by seasonal snowpack. Typically, this peak occurs between May and July, supporting the lake's water levels during the warmer months. The dynamic nature of the mountain hydrology in the Kootenay region ensures that Kootenay Lake remains a crucial resource for local flora and fauna, as well as for communities around it.
## Why the data matters here Monitoring data from the Kootenay Lake at Queens Bay station is vital for understanding the current conditions of the lake, particularly against the backdrop of its historical record. Knowing the lake's elevation compared to the median for this calendar day provides valuable insights. This contextualization allows local stakeholders, ranging from cottagers and anglers to farmers, to gauge fluctuations and make informed decisions related to water management and recreational activities.
Today's reading offers a snapshot of the lake's current status relative to its historical averages tracked by the Water Survey of Canada. By comparing today's elevation against the median over more than 50 years of data, we can better appreciate the nuances of the lake's behaviour, which is more informative than simply looking at raw elevation figures.
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.
