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 Baxter Creek at Millbrook

Baxter Creek - A vital tributary in the Otonabee watershed.

Baxter Creek flows through Millbrook in Ontario, weaving its way through the landscape while contributing to the larger Otonabee watershed. This waterway serves as a significant resource for local agriculture and recreation, feeding into a broader system that supports various flora and fauna.

The watershed context

The Otonabee watershed, where Baxter Creek is situated, is a notable area that includes neighboring streams such as Jackson Creek and the Ouse River. It encompasses a drainage area of approximately 45 square kilometers above the station, allowing Baxter Creek to effectively collect runoff and precipitation in the region. Like many Ontario waterways, Baxter Creek experiences a seasonal rhythm influenced by snowmelt. The peak flow typically occurs during the spring freshet from late April to May, while the creek naturally draws down during the dry summer months from July to September. Early winter sees a decline as ice begins to form, affecting water levels and flow rates.

Why the data matters here

Understanding the water levels of Baxter Creek is critical for local communities that rely on its resources. The data provided by the station allows stakeholders, including cottagers and farmers, to monitor the creek’s health and manage their activities accordingly. Today’s reading will be compared against the median level for this calendar day established over the past 19 years. This comparison offers a clearer perspective on current conditions, emphasizing real changes in water level that raw elevation numbers alone may not convey. With Water Survey of Canada ensuring the measurement accuracy, local residents can make informed decisions that align with the dynamic behavior of Baxter Creek throughout the seasons.

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.
