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 Wye River near Wyevale
Wye River - A vital watercourse in the Nottawasaga watershed.
The Wye River, flowing near Wyevale in Ontario, is an essential waterway in the Nottawasaga watershed. This river connects with various peers like the Boyne River and the Coldwater River, contributing significantly to the local ecosystem and hydrology. Draining an area of approximately 123 square kilometers, the Wye River plays a critical role in managing water flow and supporting the biodiversity of the region.
The watershed context
The Wye River's journey through the Nottawasaga watershed is characterized by seasonal rhythms driven largely by snowmelt. During the spring, a freshet typically occurs from late April to May, bringing a surge of water downstream. This seasonal influx is essential for replenishing aquatic habitats, while summer often sees a natural drawdown from July to September as evaporation takes its toll and inflows decrease. The early winter months also bring a decline as ice begins to form, influencing both the flow dynamics and habitat conditions for aquatic life.
Why the data matters here
Real-time readings from the Wye River gauge provide crucial insights into water conditions. This monitoring station measures both the river's stage and its discharge, allowing for a comprehensive understanding of the river's behavior throughout the year. Regular comparisons of today's water level against the median for the calendar day—derived from 38 years of historical data by the Water Survey of Canada (WSC)—offer vital context. Rather than just raw elevation figures, this median value highlights any significant fluctuations, which can be important for local cottagers, anglers, and flood-watchers who rely on reliable water conditions.
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.
