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 Petitcodiac River near Petitcodiac

Petitcodiac River - a vital waterway in New Brunswick.

The Petitcodiac River, flowing near the community of Petitcodiac, New Brunswick, is an important river in this region. Its waters are influenced by the unique hydrological patterns of the Atlantic provinces, experiencing seasonal variations that reflect the area's climate and geography.

The watershed context

This river is part of the Petitcodiac watershed, draining roughly 417 square kilometres above the measuring station. The watershed plays a critical role in the surrounding environment, capturing runoff and supporting local ecosystems. The Petitcodiac River's flow is shaped significantly by seasonal patterns, particularly the spring snowmelt freshet that may bring increased water levels and potential ice-jam risks. During the fall, rainfall can lead to floods, highlighting the dynamic nature of this waterway. The river's waters are further influenced by winter ice cover, adding another layer of complexity to its hydrology.

Why the data matters here

Today's reading of the Petitcodiac River offers essential insights into its flow and water conditions. The measure, compared to the median for this calendar day across the historical record provided by the Water Survey of Canada, helps contextualize current conditions. This gauge has been operational for more than 63 years, making its data crucial for understanding long-term trends and seasonal fluctuations on the river. By analyzing these figures, stakeholders such as local cottagers, farmers, and flood-watchers receive accurate information to make informed decisions regarding water management and land use in 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.
