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 Speed River near Armstrong Mills
Speed River - A vital tributary of the Upper Grand watershed.
The Speed River flows near Armstrong Mills in Ontario, serving as an essential waterway within the Upper Grand watershed. This river, with a catchment area of roughly 177 square kilometres above the station, is part of a larger hydrological network that includes several notable peers, such as the Grand River and the Eramosa River.
The watershed context
The Upper Grand watershed showcases a diverse range of waterways, contributing to the intricate hydrology of the region. The Speed River interacts with other significant bodies such as Blue Springs Creek and the Conestogo River, forming a rich aquatic ecosystem. This watershed benefits from snowmelt-driven seasonal hydrology, which dominates the flow patterns throughout the year. Typically, spring freshet occurs in late April to May, bringing a surge of water from melting snow, before transitioning into a natural summer drawdown from July to September as evaporation takes hold and inflows diminish.
Why the data matters here
Understanding the current reading of the Speed River near Armstrong Mills provides valuable insight into its general health and water availability. The station measures the river's discharge, which is crucial for assessing both the ecological status of the river and its capacity to support local ecosystems. Today’s reading can be compared to the median for this calendar day based on 50 years of historical data provided by the Water Survey of Canada. This context is important, as it allows for a better understanding of how current water levels measure up against historical norms, offering a clearer picture of seasonal trends and anomalies in the river's flow.
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.
