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 Bay Lake
Bay Lake - A tranquil expanse within the Timiskaming region.
Nestled in the heart of Ontario's Timiskaming region, Bay Lake offers a natural setting that appeals to outdoor enthusiasts and those seeking a moment of calm. This lake is part of the Montreal watershed, which encompasses a diverse range of habitats, making it an essential resource for the surrounding ecology.
The watershed context
Bay Lake spans a considerable drainage area, with approximately 6,273 square kilometres of land contributing to its waters. This vast catchment influences water flow patterns and quality, particularly during seasonal changes. The lake's water levels and characteristics are primarily dictated by the region's snowmelt-driven hydrology. Each spring, the freshet typically occurs in late April through May, sending a surge of meltwater into the lake and impacting its elevation. During the summer months, from July to September, evaporation and lower inflow lead to a natural drawdown, which is common for Ontario lakes.
Why the data matters here
Understanding Bay Lake's hydrology is essential for various stakeholders, including cottagers, anglers, and anyone interested in flood management. The lake's water level is monitored at the gauge "Bay Lake At Latchford," operated by Water Survey of Canada. Current readings are compared against the median water levels for this calendar day over the past 35 years. This comparison is crucial because it allows users to assess the lake's present state relative to historical norms, providing a clearer picture than raw elevation figures alone. With today's reading in mind, stakeholders can better grasp the current hydrological conditions that govern Bay Lake.
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.
