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 Northeast Margaree River at Margaree Valley

Northeast Margaree River - a vital waterway of the Margaree Valley.

Located in Nova Scotia, the Northeast Margaree River flows gracefully through the Margaree Valley, serving as an essential resource for the local ecosystem and community. This river, alongside its peer, the Southwest Margaree River, contributes to the broader Margaree watershed, which is characterized by its distinct Atlantic hydrology.

The watershed context

The Margaree River watershed includes a diverse range of landscapes, encompassing 368 square kilometers that drain into this area. As part of the Atlantic's hydrological pattern, this river experiences rain-driven floods during the fall and winter months. The spring melt, although brief, can also influence water levels, particularly in smaller basins like the Margaree. Its relatively quick response to precipitation events makes it a significant feature in forecasting local water levels and potential flooding.

Why the data matters here

Monitoring at the Northeast Margaree River gauge is essential for understanding the water dynamics in this area. Today's reading reflects how the river compares to the historical median for this date, which helps to contextualize current water levels amidst the seasonal fluctuations common to Nova Scotia. The Water Survey of Canada operates this gauge, providing invaluable data to local stakeholders. Understanding today's measurement in comparison to historical records—spanning 14 years—gives residents, farmers, and those involved in recreation peace of mind regarding expected water conditions in the region.

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.
