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.

Water Stories

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 Roaring River near Minitonas

Roaring River - A vital waterway in the Shoal watershed.

The Roaring River flows near Minitonas, Manitoba, creating an essential channel within the Shoal Watershed. This river, with a catchment area of approximately 858 square kilometres, serves as a crucial ecological and hydrological feature in this region.

The watershed context

As part of the Shoal Watershed, the Roaring River connects with nearby waterways, including the Birch River and the Swan River. These rivers collectively contribute to a dynamic local hydrology, which is particularly influenced by the seasonal rhythms typical of the Prairie region. Spring snowmelt is often the highlight, bringing significant water flow that can lead to flooding events. In contrast, the summer months typically see a reduction in water levels due to evaporation and lower inflows.

Why the data matters here

Monitoring hydrological data from the Roaring River near Minitonas is essential for understanding local water conditions. The station measures both water levels and discharge, providing valuable information that can help inform users like farmers, cottagers, and flood-watchers. Today's water level readings should be compared against the median for this calendar day across the station's 49 years of historical data, as this context is vital in assessing current conditions beyond just a raw elevation. Such comparisons can highlight deviations that may affect both community planning and ecological health, enabling users to take proactive measures in response to changing water conditions. The data is sourced from the Water Survey of Canada (WSC), which ensures that these readings are reliable and accurate.

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.
