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.

Water Stories

The flood of record that was overtaken

For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.

About Credit River Erin Branch above Erin

Credit River Erin Branch - a vital waterway for the local ecosystem.

The Credit River Erin Branch flows gracefully above the charming community of Erin, Ontario. This river is an essential part of the Credit - 16 Mile watershed and plays a crucial role in supporting both the environment and community activities. As a river that spans 36.1 square kilometres in its upstream drainage area, this branch provides habitat for aquatic species and contributes significantly to the regional hydrology.

The watershed context

The Credit River Erin Branch is surrounded by a diverse array of waterways, including peers such as Cooksville Creek near Cooksville and Credit River at Streetsville. This network of rivers and creeks fosters a rich aquatic ecosystem that benefits from seasonal changes driven by snowmelt, particularly during the spring freshet occurring in late April to May. As temperatures rise and melting snow enters the river system, flows tend to peak, revitalizing the area before the natural summer drawdown takes place from July to September. This seasonal rhythm not only influences the river's flow but also affects local agriculture, recreation, and wildlife activity.

Why the data matters here

Monitoring the Credit River Erin Branch is essential, particularly as it provides actionable data on streamflow and water levels. Today's reading captured at the gauge is compared to the historical median for this date, allowing for a clearer understanding of current conditions within the context of past records. With 43 years of data collected by the Water Survey of Canada, this metric offers valuable insights into the river's health and its responses to seasonal changes, guiding the stewardship of this important local resource.

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.
