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 Black River near Actinolite
Black River - a dynamic tributary of the Moira watershed.
The Black River flows near Actinolite, Ontario, contributing to the rich hydrology of the Moira watershed. This waterway is one among several local rivers, including the Clare River near Bogart and the Moira River near Tweed. With a drainage area encompassing roughly 433 square kilometres, the Black River channels the natural rhythms of seasonal water dynamics characteristic of the region.
The watershed context
The Black River is integral to the Moira watershed, reflecting the area’s snowmelt-driven seasonal hydrology. During spring, typically late April through May, the river experiences a freshet as snow melts, delivering peak flows that nourish the surrounding ecology. As summer arrives, the river naturally sees a drawdown from July to September, largely due to evaporation and reduced inflow. Entering fall and early winter, flow levels gradually decline again as ice formation occurs, heralding the onset of colder months.
Why the data matters here
Understanding the significance of today's water level is crucial for locals monitoring river conditions. With a historical dataset spanning over 50 years, the current reading serves as a crucial reference point against the median for this calendar day, providing insights into the river's behavior over time. This comparison, facilitated by the Water Survey of Canada, offers greater clarity than raw elevation figures, helping residents and visitors alike stay informed about variations within this important waterway.
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.
