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 Dunk River at Wall Road

Dunk River - A vital waterway on Prince Edward Island.

Nestled in the picturesque landscape of Central Prince Edward Island, Dunk River flows gracefully at Wall Road, nurturing a catchment area of approximately 114 square kilometres. This river, with its roots in rain and snowmelt, is fed by groundwater, which provides a steady baseflow even during drier periods. The characteristic Atlantic island hydrology showcases a short spring freshet, while the river maintains a regulated flow through the seasonal variations of rainfall and melting snow.

The watershed context

The Dunk River is part of the Central Prince Edward Island - Wilmot watershed, which supports a network of waterways including nearby Barbara Weit Stream at Cavendish Farm and Wilmot River near Wilmot Valley. This region's rich hydrology is characterized by its reliance on precipitation and groundwater, resulting in resilient streams that withstand the seasonal changes. As part of this watershed, Dunk River plays a crucial role in sustaining the local ecology and water needs for the surrounding communities.

Why the data matters here

The Dunk River at Wall Road station provides valuable data to understand the river's health and flow dynamics. The station monitors river discharge, allowing for crucial comparisons against historical records maintained over the past 14 years. Monitoring water levels against the median for this calendar day offers insights into the river's behaviour amidst ongoing environmental changes. This comparison is essential for various stakeholders, including local farmers, cottagers, and residents, who rely on accurate water intelligence provided by Water Survey of Canada. Keeping a pulse on the Dunk River’s flow helps ensure informed decisions for those who interact with this important waterway.

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.
