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 near Doon
Grand River near Doon - A vital watercourse in the Upper Grand watershed.
The Grand River near Doon flows through the heart of Ontario's Upper Grand watershed, presenting a dynamic waterway that both shapes and reflects the local environment. This river serves as a crucial resource for the surrounding communities while also supporting diverse aquatic ecosystems. With its catchment area of approximately 2,500 square kilometers, the Grand River collects and channels water from numerous tributaries and nearby features, including Blue Springs Creek and Canagagigue Creek.
The watershed context
Snowmelt-driven seasonal hydrology characterizes this region. Spring freshet typically occurs from late April to May as melting snow contributes to elevated water levels, while natural summer drawdown is observed from July to September, driven by evaporation and reduced inflow. As fall leads into early winter, water levels decline again as ice begins to form.
Being part of a larger hydrological network, the Grand River interacts with other waterways in the area, including the nearby Conestogo River and Eramosa River. This connectivity not only enriches the region's water quality but also supports a variety of recreational activities, making it a favored spot for fishers, paddlers, and nature enthusiasts alike.
Why the data matters here
Monitoring water levels and discharge is essential for understanding the behavior of the Grand River. Today's reading from the Water Survey of Canada shows the river at a level that can be compared against the median for this calendar day, based on a historical record spanning nearly 19 years. This approach provides context far beyond a single measurement, revealing trends and anomalies in water flow that are vital for local management and conservation efforts. Such data informs residents, farmers, and flood-watchers about the river's current state, helping them make informed decisions throughout the changing seasons.
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.
