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 Kelley Lake
Kelley Lake - a tranquil body in the Vermilion watershed.
Kelley Lake is a significant feature of Ontario's Vermilion watershed, embodying the characteristics of the region's snowmelt-driven water cycle. This lake plays an essential role in the local hydrology, supporting not only its ecosystem but also the communities that rely on its waters throughout the changing seasons.
The watershed context
Kelley Lake is part of a bigger hydrological system, with a drainage area of approximately 211 square kilometres upstream of the gauge that measures peak activities on Junction Creek below the lake. This connectivity to broader systems is crucial during the seasonal phases marked by snowmelt in late April through May, leading to a spring freshet. As the warmer months approach, typically from July through September, Kelley Lake experiences natural summer drawdown as evaporation and reduced inflow gradually lower the water levels. The early winter months see a decline as ice forms, marking the transition into a quieter period of the lake's hydrological rhythm.
Why the data matters here
Regular measurements taken from Kelley Lake provide invaluable insights into the lake's water levels and flow characteristics. Today's reading will be contextualized against the median for this calendar day over the station's 23 years of historical data collected by Water Survey of Canada (WSC). This comparative approach helps gauge periods of fluctuation more accurately than raw elevation figures alone, shedding light on seasonal trends and making it easier for local stakeholders, including cottagers and anglers, to understand the lake's current state.
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.
