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.

The flood of record that was overtaken

For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.

North River at the Falls Water Level

Live river level, flow, historical records and forecast for North River at the Falls in Canada, ON, Canada, built from official government gauge data.

About North River at the Falls

North River at the Falls - a lively tributary of the Nottawasaga watershed.

The North River, flowing at the Falls, is a notable feature in Ontario’s Nottawasaga watershed. This river is part of a network that supports both the local ecology and the recreational activities of cottagers and anglers alike. With a significant drainage area of approximately 244 square kilometres, the North River helps manage and balance the water flow within the broader watershed context.

The watershed context

The North River is nestled within the Nottawasaga watershed, a vital area that hosts several other water bodies including the Boyne River, Coldwater River, and the Nottawasaga River itself. This watershed plays a critical role in regional hydrology, particularly with its snowmelt-driven seasonal patterns. As spring approaches, the North River experiences a robust freshet from late April through May, marked by rising waters due to melting snow. During the summer months from July to September, natural drawdown occurs, driven by both evaporation and reduced inflow. Early winter sees a gradual decline in water levels as ice begins to form, showcasing the cyclical nature of the river’s hydrology.

Why the data matters here

Water data for the North River at the Falls is crucial for a variety of stakeholders, including local farmers, anglers, and flood-watchers. It not only measures elevation but also informs about the river’s flow conditions, enhancing decision-making processes around agriculture and recreation. The current reading is benchmarked against the median for this calendar day across the station's 36 years of historical data, a practice that offers a clearer understanding of water conditions than raw elevation alone. This information is provided by the Water Survey of Canada, ensuring that all stakeholders can stay informed and prepared for the dynamics of North River.

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.
