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 Riviere Delisle near Glen Norman

Riviere Delisle - A hallmark of seasonal flow.

The Riviere Delisle near Glen Norman showcases the vibrant patterns of seasonal hydrology typical of Ontario's rivers. As part of the Upper St. Lawrence - Raisin watershed, this river plays a crucial role in the surrounding landscape, not only serving the local ecosystems but also providing vital water resources for nearby communities and activities.

The watershed context

Draining roughly 158 square kilometres above the gauge station, Riviere Delisle meanders through a diverse environment before confluencing with other regional waterways. It shares its watershed with noteworthy peers such as the Garry River and the Raisin River. This network of rivers contributes to the overarching hydrological cycle that dictates the area's annual rhythms—from the spring freshet that swells the waters in late April and May, to the gradual natural drawdown observed during the summer months of July through September.

Why the data matters here

The current measurement obtained from the Water Survey of Canada (WSC) is invaluable; it reflects today's reading in relation to the median for this calendar day over a 23-year span. Such comparisons allow for a deeper understanding of current water conditions by providing context against historical trends. Rather than relying solely on elevation figures, this approach helps gauge the responsiveness of the river to seasonal changes and climatic variations, making it a vital resource for cottagers, anglers, and stakeholders within the area.

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.
