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 Big Presque Isle Stream at Tracey Mills

Big Presque Isle Stream - a vibrant waterway of New Brunswick.

Nestled in the Central Saint John - Becaguimec watershed, Big Presque Isle Stream flows with purpose at Tracey Mills. This river plays a vital role in the local hydrology, contributing to the dynamic water network that includes nearby Becaguimec Stream and the Meduxnekeag River. Draining an area of approximately 487 square kilometres, this stream serves as a life source for the surrounding landscape and communities, shaped significantly by the Atlantic hydrology patterns of New Brunswick.

The watershed context

The Central Saint John - Becaguimec watershed is influenced by the typical seasonal rhythms of New Brunswick, featuring a spring snowmelt freshet that can lead to ice-jam risks on major rivers. As winter approaches, this region experiences ice cover, while significant fall rain can lead to floods. Such hydrological events impact not only the stream’s flow but also the surrounding ecosystem and local activities.

Big Presque Isle Stream is connected to its peers, Becaguimec Stream and the Meduxnekeag River, creating a network of waterways that are essential for ecology and local recreation. This stream, along with its companions, supports fishing, wildlife habitats, and the broader environment, providing various opportunities for those who reside nearby or visit.

Why the data matters here

Today's water level reading at Big Presque Isle Stream is compared against the median for this calendar day across 58 years of historical data tracked by Water Survey of Canada. This comparison is crucial as it provides insight into current hydrological conditions, offering a clearer perspective than raw elevation alone. Understanding the stream’s behavior over time helps local residents and water-watchers anticipate conditions such as potential flooding or drought. Seasonal changes and their impacts are better managed when informed by solid data, emphasizing the importance of this ongoing hydrological monitoring.

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.
