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.

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.

East Humber River at King Creek Water Level

Live river level, flow, historical records and forecast for East Humber River at King Creek in Canada, ON, Canada, built from official government gauge data.

About East Humber River at King Creek

East Humber River - A vital waterway in the Humber - Don watershed.

The East Humber River flows gracefully through the heart of Ontario, serving as an important conduit within the Humber - Don watershed. Stretching across a catchment area of approximately 95 square kilometres, this river plays a crucial role in the hydrology of the region. The station at King Creek provides critical data for monitoring the river's conditions, ensuring that residents and stakeholders can track its health and flow variations.

The watershed context

The hydrology of the East Humber River is significantly influenced by the seasonal patterns typical of southern Ontario. The spring freshet, occurring in late April to May, is driven by melting snow, which results in higher water levels and increased flow rates. As summer approaches, natural drawdown begins, characterized by reduced inflows and evaporation, which sees water levels typically declining from July to September. As the seasons shift towards early winter, the river experiences another period of decline as ice formations begin to affect its flow.

The East Humber River is accompanied by several notable peers within the Humber - Don watershed, including Black Creek, Don River East Branch, and Highland Creek. These rivers share a similar trajectory of seasonal hydrology, forming an interconnected network that supports local ecosystems and communities.

Why the data matters here

The data collected at the East Humber River station helps inform agricultural practices, recreational planning for cottagers and anglers, and flood management efforts. By monitoring the river's flow, the Water Survey of Canada can provide timely information that enhances public safety and environmental stewardship.

Today's reading is measured against the median for this date based on nearly 49 years of historical data. This context allows for a better understanding of current conditions, as it reveals trends and shifts in flow relative to what is typically expected. This kind of insight is invaluable for anyone relying on the river's resources or concerned with its ecological health.

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.
