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 Pretty River at Collingwood
Pretty River - a vital tributary to the Nottawasaga.
The Pretty River flows through Collingwood, Ontario, carving a path that reflects the dynamic rhythms of the Nottawasaga watershed. This river, measuring flow and draining roughly 68.8 square kilometres above the station, plays an essential role in the region's hydrology, linking the landscape to the broader ecological system.
The watershed context
Nestled within the Nottawasaga watershed, the Pretty River is part of a diverse network of waterways that contribute to the ecological health of the area. It has several peers including the Boyne River at Earl Rowe Park and the Coldwater River at Coldwater, each sharing the landscapes and environmental conditions of this distinctive region. The seasonal hydrology here is primarily snowmelt-driven, experiencing its peak flow during the spring freshet in late April to May, while natural summer drawdown typically occurs from July to September. As winter approaches, the river's flow slows further with early-winter declines coinciding with the formation of ice.
Why the data matters here
Understanding the flow measurements from the Pretty River at Collingwood is vital for various stakeholders, from local residents to environmentalists and agricultural planners. Tracking flow helps gauge water availability and informs decisions about usage, while providing essential insights into seasonal patterns. As of today, the river's reading is compared to the historical median for this calendar day, offering a more accurate picture of current conditions over its 19 years of record-keeping by Water Survey of Canada. This comparison transcends mere elevation; it allows observers to assess how the current flow stands in relation to typical seasonal trends, facilitating better understanding and management of water resources.
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.
