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 York River near Bancroft

York River - A vibrant aquatic corridor near Bancroft.

The York River flows gracefully near Bancroft in Ontario, serving as a critical watercourse within the Upper Madawaska watershed. Spanning a drainage area of approximately 844 square kilometres, this river is part of a network that sustains both natural ecosystems and human activity within the region. Its shared environmental influence is notable, with the Madawaska River at Palmer Rapids as a nearby counterpart.

The watershed context

As a snowmelt-driven system, the hydrology of the York River reflects the characteristic seasonal rhythms of eastern Ontario. Spring freshets occur in late April and May when melting snow feeds the river, resulting in elevated water levels. This seasonal surge supports the aquatic life and increases water flow through the river's winding path. During the summer months, from July to September, natural drawdown occurs due to evaporation and reduced inflow, shaping the river's low-water conditions. Early winter sees a decline as ice forms, signaling the transition into colder months.

Why the data matters here

Monitoring the York River's water levels is essential for various stakeholders, including anglers, cottagers, and local farmers. The gauge at this location provides valuable data on river conditions, helping to inform fishing patterns and agricultural practices in the vicinity.

As of today, the water level reading from the York River near Bancroft, reported by the Water Survey of Canada, is compared against the median for this calendar day across more than 50 years of historical data. This comparative measure offers a more useful insight than raw elevation alone, supporting informed decisions for those who rely on or interact with this watercourse.

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.
