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.

About Wilmot Creek near Leskard

Wilmot Creek - A vital waterway in the Ganaraska watershed.

Wilmot Creek flows near Leskard, Ontario, meandering through a vital stretch of the Ganaraska watershed. This flowing waterway plays a significant role in the local hydrology and ecology, serving as a connecting vein for wetland ecosystems and agricultural lands alike. With a drainage area of approximately 23.2 square kilometres upstream from the station, it captures the varied influences of rainfall and snowmelt typical of this semi-urban region.

The watershed context

The Ganaraska watershed encompasses a diverse network of waterways, including notable peers such as Baltimore Creek and Oshawa Creek. Each of these rivers, along with Wilmot Creek, contributes to the area's overall hydrological health. The seasonal cycle in this region is primarily snowmelt-driven, reflected in the spring freshet that typically peaks from late April to May. During summer, natural drawdowns occur as evaporation and low inflows set in, with water levels gradually declining from July through September. As early winter approaches, a further decline in water levels is anticipated as ice begins forming, marking the onset of the colder months.

Why the data matters here

Understanding the data from Wilmot Creek is crucial for local stakeholders, including cottagers and farmers, who depend on accurate water levels for their activities and crop management. The current data reflects today's water level, which can be compared to the historical median for this calendar day over the last 19 years. By providing context for daily fluctuations, the information helps gauge the creek's health and predict upcoming changes, proving more insightful than raw elevation figures. This information is compiled by the Water Survey of Canada, ensuring reliable monitoring of this important waterway.

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.
