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 North Muskoka River at Port Sydney
North Muskoka River - A lively waterway flowing through Ontario's Muskoka region.
The North Muskoka River at Port Sydney serves as a vital artery in Ontario's scenic Muskoka region. This river, which drains a substantial catchment area of approximately 1,413 square kilometres, presents an ever-changing landscape for both local wildlife and water enthusiasts. As a tributary in the Muskoka watershed, it plays a crucial role in supporting the diverse aquatic ecosystems and contributing to the hydrological dynamics of this beautiful area.
The watershed context
The North Muskoka River is part of a rich network of lakes and rivers that characterize the Muskoka region, which includes notable peers such as Big East River, Fairy Lake, and Lake Muskoka. This interconnected hydrological system demonstrates the natural seasonal rhythms, marked especially by snowmelt. The spring freshet typically peaks in late April and May, when the warmer weather initiates snowmelt, leading to increased flow in the river. As summer approaches, natural drawdown occurs from July to September, resulting from evaporation and reduced inflow. In early winter, as the temperatures drop, the river experiences a decline in flow accompanied by ice formation.
Why the data matters here
Monitoring the North Muskoka River's flow is essential for understanding the health of both ecosystems and human activities in the area. Today's reading from the Water Survey of Canada reveals the current flow conditions in terms of river elevation. By comparing this measurement with the historical median for this date over the station's 49 years of records, we gain insight into how current water levels relate to long-term trends and seasonal expectations. This comparison is more informative than a single reading, providing context to assess the effects of seasonal cycles and climate influences on the river's health and stability.
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.
