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.

About Nashwaak River at Durham Bridge

Nashwaak River - A vital waterway in New Brunswick.

The Nashwaak River at Durham Bridge is an important natural feature in New Brunswick, flowing through a watershed that encompasses a considerable drainage area of roughly 1,450 square kilometres. This river plays a significant role in the regional hydrology, influenced by the rhythms of Atlantic Canada, particularly the spring freshet driven by melting snow and the potential for ice jams on major rivers, like the Nashwaak.

The watershed context

The Nashwaak River winds through a rich landscape characteristic of New Brunswick's diverse ecosystems. Its catchment, which supports an array of wildlife and habitats, is also vital for local agriculture and recreational activities. Nearby, Narrows Mountain Brook flows, further contributing to the hydrology of the region. The confluence of these waterways fosters a dynamic environmental setting, sustaining both flora and fauna along the banks.

In the spring, the river experiences heightened flows due to snowmelt, which can lead to freshet conditions and sporadic flooding. In fall, the risk of rain floods emerges, showcasing the river's responsive nature to seasonal changes and precipitation patterns. As part of New Brunswick's intricate water system, the Nashwaak River is subject to winter ice cover, which can create unique conditions for local wildlife while also presenting challenges for navigation and monitoring.

Why the data matters here

Understanding the water levels and discharge measurements at the Nashwaak River at Durham Bridge is crucial for monitoring the health of this vital ecosystem and mitigating flood risks. Today's readings reveal the current status of the river compared to historical trends, providing essential insights for local anglers, cottagers, and farmers. Water levels are compared against the median for this calendar day across the station's historical data, spanning more than 14 years. This offers a clearer picture than raw elevation alone and is crucial for informed decision-making. The data is published by the Water Survey of Canada, ensuring that stakeholders have access to reliable and timely information about this significant 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.
