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 Lake Nipissing
Lake Nipissing - A large, vital water body in Ontario's landscape.
Lake Nipissing is a significant lake located in the heart of Ontario, primarily within the Nipissing region. This expansive body of water plays an essential role both ecologically and in providing recreational opportunities to visitors and locals alike. With a catchment area of approximately 12,300 square kilometers above the gauge at North Bay, Lake Nipissing is interlinked with several smaller lakes and rivers, including Dollars Lake, Forest Lake, and the French River system.
The watershed context
Part of the French watershed, Lake Nipissing serves as a crucial hub for the water systems that flow through this picturesque region. The lake is characterized by a distinct seasonal rhythm, typical of many water bodies in Ontario. The annual cycle includes a snowmelt-driven spring freshet in late April and May, leading to higher water levels. This peak is followed by a natural drawdown during the summer months, as evaporation and lower inflows take their toll. As winter approaches, the lake experiences a gradual decline in water levels as ice begins to form and snow accumulates in the surrounding landscape.
Why the data matters here
Monitoring water levels is essential for numerous reasons. Today's reading from the Water Survey of Canada station at North Bay provides valuable insight into the lake's current state compared to the historical median for this calendar day over the last 49 years. This comparison is instrumental in identifying trends and understanding the natural fluctuations of water levels. For cottagers, anglers, and those reliant on the lake's health, accessing reliable data is vital for decision-making in recreational activities and resource management, ensuring that Lake Nipissing remains a vibrant part of the region for generations to come.
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.
