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 Forest Lake
Forest Lake - A natural haven in Parry Sound.
Nestled within the French River watershed, Forest Lake is an inviting body of water that supports a diverse ecosystem and offers a serene environment. This lake is complemented by a network of neighboring waters, including Dollars Lake and the iconic French River. Each contributes to the rich hydrology of the area, collectively shaping the landscape and providing essential water resources.
The watershed context
Forest Lake is part of a larger drainage area, with approximately 321 square kilometres of land feeding into it. This catchment supports the lake during various seasonal rhythms. Ontario experiences a snowmelt-driven hydrological cycle, with spring freshet typically peaking from late April to May. During this time, runoff from melting snow replenishes lakes and rivers, including Forest Lake. As we move into summer, natural evaporation and low inflow can lead to gradual drawdown from July through September, which is part of the normal seasonal pattern. Early winter sees water levels decline further as ice begins to form across the lake’s surface.
Why the data matters here
Today’s water level reading for Forest Lake is an important indicator of its health and hydrological behavior. It is essential to understand how this reading compares to the median level for this calendar day over the past 21 years to appreciate its context. Tracking this data through the Water Survey of Canada helps to reveal trends and support the management of natural resources in the area. Knowing the water level against historical norms assists cottagers, anglers, and those involved in local agriculture in making informed decisions throughout the year.
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.
