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 Grand River at West Montrose
Grand River at West Montrose - a vital tributary of the Upper Grand watershed.
Nestled within the lush landscape of Ontario, the Grand River at West Montrose plays an important role in the local ecosystem and community. Covering a drainage area of approximately 1,160 square kilometres upstream, this stretch of the Grand River is known for its natural variability and vital contribution to regional hydrology. This river, along with its peers such as Blue Springs Creek and the Eramosa River, supports the diverse needs of the area’s flora, fauna, and human inhabitants alike.
The watershed context
The Grand River at West Montrose is a significant part of the Upper Grand watershed, which encompasses various tributaries flowing through fertile farmland and vibrant ecosystems. As snowmelt contributes to the river's flow in spring, the seasonal hydrology is characterized by a freshet typically occurring from late April to May. During summer months, natural drawdown occurs from July to September as evaporation takes its toll and inflows decrease. This cycle ensures that habitats are nourished during critical phases of growth, while also establishing a rhythm that the wildlife in the area depends on.
Why the data matters here
Monitoring the Grand River is essential for understanding its health and the overall condition of the Upper Grand watershed. Today's data indicates the river's current level compared to historical medians, which assists stakeholders in making informed decisions about water use, conservation practices, and ecosystem management. The data is particularly valuable when evaluating variations caused by seasonal shifts and climate influences.
Given it has been recorded for over 50 years, the Water Survey of Canada provides vital information on the river's conditions, helping those who live near or depend on it—be they cottagers, anglers, or farmers. Understanding where today's reading stands against the median for this date offers a clearer picture than merely observing the raw elevation; it highlights trends in flow and elevation, essential for safeguarding this critical water source.
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.
