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 Mackie Creek near Hampton

Mackie Creek - a vital waterway in the Ganaraska watershed.

Mackie Creek meanders through the charming landscape near Hampton, Ontario, playing a significant role in the local hydrology and ecosystem. This river, part of the larger Ganaraska watershed, showcases the area's snowmelt-driven seasonal water patterns. With a drainage area of approximately 18 square kilometres above the station, it collects runoff from the surrounding terrain, contributing to the region's intricate water dynamics.

The watershed context

The Ganaraska watershed is characterized by its diverse waterways, including notable peers like Baltimore Creek and Oshawa Creek. Each of these rivers and creeks, including Mackie, responds to seasonal changes, particularly during the spring freshet from late April to May when snowmelt swells their flows. During the summer months, evaporation and low inflow lead to a natural drawdown, reflecting the region's typical hydrological rhythm. As fall approaches, the water levels gradually decline, particularly as ice begins to form in early winter.

Why the data matters here

Understanding the hydrological data from Mackie Creek is essential for monitoring its conditions and assisting the community that relies on its waters. The gauge not only measures water elevation but also provides insight into its flow, which is crucial for various stakeholders, including local farmers and flood-watchers. For instance, today's reading compared against the median for this calendar day—and the record of 19 years maintained by Water Survey of Canada—offers a clearer picture than raw elevation alone. Such comparisons highlight trends over time, helping to inform local water management practices and ensuring a sustainable relationship with 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.
