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 Irvine River near Salem
Irvine River - a vital waterway in the Upper Grand watershed.
The Irvine River near Salem serves as an essential artery within Ontario's Upper Grand watershed. With a drainage area of approximately 196 square kilometres, this river is pivotal for maintaining local ecosystems and providing water resources for the surrounding communities. The river flows in the embrace of its peers, including Blue Springs Creek and the Grand River, forming a network of waterways that contribute to the diverse hydrology of the region.
The watershed context
The Upper Grand watershed is a landscape shaped by snowmelt-driven seasonal hydrology. During the spring, typically late April to May, meltwater from snowpack leads to a freshet, resulting in increased flow across the rivers in the area, including the Irvine River. This rise supports aquatic ecosystems and local flora and fauna, as diverse habitats flourish with the rush of water. As summer approaches, natural drawdown occurs from July to September, with evaporation and reduced inflow leading to lower water levels. This rhythm continues into early winter when ice begins to form and flows decline further, signaling another seasonal change.
Why the data matters here
Regular monitoring of the Irvine River, conducted by the Water Survey of Canada, provides vital insights into the river’s health and performance over time. Today’s reading at the Irvine River near Salem can be compared against the historical median for this calendar day, aiding in understanding current conditions. Tracking this data is crucial not only for assessing the riparian ecosystem's vitality but also for water management in agriculture and community usage. With 19 years of record-keeping, this gauge informs local stakeholders about trends in water levels, helping them prepare for the seasonal shifts that characterize the Upper Grand watershed.
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.
