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 Meduxnekeag River near Belleville

Meduxnekeag River - A vital waterway in New Brunswick.

The Meduxnekeag River flows near Belleville, serving as a crucial ecological and hydrological feature in the region of New Brunswick, Canada. This river is part of the Central Saint John - Becaguimec watershed, which covers an extensive area and is supported by various tributaries, including notable peers like Becaguimec Stream and Big Presque Isle Stream.

The watershed context

Draining approximately 1,210 square kilometres, the Meduxnekeag River plays an essential role in managing runoff and ecosystem health within its catchment. The hydrology of New Brunswick is characterized by a spring snowmelt freshet, presenting flows that can swell with ice-jam risks on the major rivers. Autumn often introduces rains that can lead to flooding, while winter sees the river's surface covered with ice. This seasonal rhythm greatly influences water levels and flow characteristics, making it vital for local agriculture, fishing, and wildlife habitats sustaining the area.

Why the data matters here

Understanding water metrics is crucial for anyone reliant on the Meduxnekeag River, whether for recreational, agricultural, or environmental purposes. Today's river level reading is a key indicator, reflecting how current conditions compare to historical norms. The Water Survey of Canada operates the measuring station for the Meduxnekeag River near Belleville, and today’s level is assessed against the median for this calendar day over the past 58 years. Tracking this data not only helps in managing flood risks but also provides insights into the overall health of the river ecosystem and its capacity to support local wildlife and human activities.

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.
