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 Grande Riviere at Violette Bridge

Grande Riviere at Violette Bridge - a flowing connection in New Brunswick’s Upper Saint John - Verte watershed.

The Grande Riviere at Violette Bridge is a vital watercourse in New Brunswick, contributing to the intricate hydrology of the Upper Saint John - Verte watershed. This river serves as a crucial avenue for both wildlife and human activities, weaving through the landscape with a drainage area of approximately 325 square kilometres above the gauge. It stands among notable peers, including the Iroquois River at Moulin Morneault and the Saint John River at Grand Falls, forming a network of waterways that sustain the region’s ecosystems.

The watershed context

This river plays an integral role in the local hydrological cycle, which is influenced by Atlantic weather patterns. In spring, the melting snow tends to cause a freshet, bringing increased flow levels that can create substantial risks of ice jams along the riverbanks. Additionally, the region typically experiences fall rain floods that can further elevate water levels, presenting unique challenges and opportunities for the surrounding flora and fauna.

As winter approaches, ice cover can form on many streams, including the Grande Riviere, influencing how both aquatic life and the river's flow dynamics behave during the colder months. Observing these seasonal changes is crucial not only for understanding the river's health but also for local activities such as fishing and agriculture, where water availability is vital.

Why the data matters here

The current hydrological data for the Grande Riviere at Violette Bridge is significant for assessing water levels and conditions. By monitoring the gauge readings, users can compare today's data against the historical median for this calendar day, providing context that raw elevation alone cannot offer. With 49 years of records from the Water Survey of Canada, this approach allows for a deeper understanding of trends and variations in water flow. Such insights are invaluable for cottagers, anglers, farmers, and others who rely on this river's resources—helping them make informed decisions in their activities and interactions with the environment.

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.
