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.

Water Stories

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.

About East Humber River near Pine Grove

East Humber River - A vital vein in Ontario's hydrology.

The East Humber River near Pine Grove flows gracefully through a landscape intertwined with nature and urban development. As part of the Humber - Don watershed, this river serves as an essential conduit for Rainwater and snowmelt, providing vital resources to the surrounding ecosystem and communities. The area's hydrology follows a typical seasonal rhythm characterized by snowmelt-driven freshets in late April to May, a natural summer drawdown from July to September, and an early-winter decline as ice begins to form.

The watershed context

Draining roughly 196 square kilometres above the station, the East Humber River collects water from diverse sources, making it critical to the overall health of the Humber - Don watershed. It shares its neighbourhood with notable peers, including Black Creek and several branches of the Don River, each contributing to the dynamic water systems of this region. These rivers interact and support each other, ensuring the stability and resilience of the local hydrology.

The seasonal variations in water levels can significantly influence both aquatic and terrestrial ecosystems, showcasing the importance of understanding the river’s flow and gauge readings. By monitoring the East Humber River, we can gain insights into the broader hydrological context of the area, which includes the impact of urban development and landscape changes in the surrounding regions.

Why the data matters here

Today's reading for the East Humber River provides valuable context when compared to the median for this calendar day over 49 years of recorded history. This comparison, as managed by the Water Survey of Canada, is crucial, as it helps to illustrate the current water level relative to historical patterns, allowing for better flood prediction, water resource management, and environmental protection. Understanding these variations informs us not just about the river's health but also about the broader ecosystem it supports. By relying on daily gauge measurements, we can safeguard both water quality and quantity for all who depend on this river's resources.

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.
