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.

About Moon River at Hwy 400
Moon River - A seasonal lifeline in Muskoka.
Flowing with the rhythm of the seasons, the Moon River at Highway 400 is a crucial component of the Muskoka watershed, which is known for its interconnected lakes and rivers. This river nurtures both the habitats it traverses and the people who rely on its water. With a catchment area of approximately 4,790 square kilometres, the Moon River serves as a vital artery that sustains the natural beauty and biodiversity of this region.
The watershed context
The Moon River is flanked by several prominent lakes in the Muskoka region, including Lake Joseph, Lake Rosseau, and Lake Muskoka. Each of these bodies of water contributes to a network that captures the melting snow and rainfall typical of Ontario's spring months. As snowmelt fills the river, the seasonal hydrology is notably active, peaking in flow during the late April to May freshet. This spring surge supports aquatic life and replenishes local ecosystems after the colder winter months.
As the summer approaches, water levels gradually decline from natural evaporation and reduced inflow, a pattern expected from July through September. By early winter, the river’s flow will see another decline as frost sets in and ice begins to form.
Why the data matters here
Monitoring water levels at the Moon River gives insights into the health of the surrounding environment, impacting both wildlife and the local community. Each reading at the gauge informs residents, cottagers, and outdoor enthusiasts about current conditions, allowing for better planning of recreational activities and critical assessments regarding water quality and availability.
Today's reading will be compared against the median for this calendar day over the historical record of almost 50 years, a practice that offers context and understanding beyond just an elevation number. This analysis is managed by the Water Survey of Canada, ensuring that you have the most reliable information at your fingertips for navigating the seasonal changes of this vibrant river.
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.
