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 at Cambridge
Speed River - a vital artery of the Upper Grand watershed.
The Speed River at Cambridge is a significant waterway that flows through the heart of Ontario's Upper Grand watershed. This river, stretching with a drainage area of approximately 761 square kilometers, plays a crucial role not only in the local ecosystem but also for the communities and activities that surround it. Residents and visitors alike appreciate the river's dynamic nature and the vital functions it serves.
The watershed context
The Speed River is part of a larger network of waterways that includes notable peers such as the Grand River, Eramosa River, and Blue Springs Creek. This interconnected hydrological system supports a variety of aquatic life and provides valuable resources for agriculture and recreation. The Upper Grand watershed is marked by its snowmelt-driven seasonal hydrology. As spring arrives, the river swells with the freshet, typically peaking late April to May, which signifies a period of high flow as the winter snowpack melts. During the summer months from July to September, natural drawdown occurs as evaporation rates increase and inflow decreases, leading to lower water levels. The transition into early winter brings a decline in water levels as the river begins to ice over, marking the changing seasons in this vibrant landscape.
Why the data matters here
Monitoring the Speed River is essential for understanding its flow dynamics and seasonal variations. Currently, the water level data from the Water Survey of Canada helps gauge the river's health, offering insight into ecological conditions and hydrological trends. Today's reading, when compared against the median for this calendar day over the station's 22-year historical record, is a critical metric. It allows for a better understanding of the river's current state and helps manage the effects of fluctuating water levels on the surrounding environment and community activities. This context is invaluable for cottagers, anglers, and flood-watchers who rely on accurate and timely data to make informed decisions.
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.
