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 Dennis Stream near St. Stephen

Dennis Stream - a gentle rippling in the St. Croix watershed.

Dennis Stream flows gracefully near St. Stephen, New Brunswick, covering a drainage area of roughly 114 square kilometres above the station. The stream plays its part in the wider St. Croix watershed, connecting with nearby waters like Forest City Stream and Grand Falls Flowage, and serving as an integral component of this rich aquatic network.

The watershed context

This region, characterized by the Atlantic hydrology, experiences a distinct seasonal rhythm. Each spring sees a freshet from melting snow, which, combined with the potential for ice jams on major rivers, can affect the water levels in Dennis Stream. As the seasons progress into fall, rain can contribute to flooding events, while winter brings a blanket of ice cover. This cycle of seasonal changes impacts the flow of Dennis Stream, influencing the surrounding ecosystem and its inhabitants.

Why the data matters here

Monitoring the data from Dennis Stream is crucial for understanding its health and flow patterns. The station not only measures elevation but also provides discharge information, offering insights into the volume and speed of water moving through the stream. Today's reading, taken from the Water Survey of Canada, can be compared against the median for this calendar day over a historical record of 58 years. This comparison is more informative than raw elevation alone, as it shows how current conditions stack up against long-term patterns, helping stakeholders like local farmers and flood-watchers make informed decisions.

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.
