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 Assiniboine River at Brandon

Assiniboine River at Brandon - A vital waterway in Manitoba.

The Assiniboine River at Brandon flows with purpose through the heart of Manitoba. Serving as a crucial artery for both ecological connections and human activities, this river is part of the Central Assiniboine - Cypress watershed and influences a considerable drainage area upstream, encompassing roughly 84,800 square kilometres. Known for supporting local industries and recreational activities, the river also plays a vital role in flood management and environmental health in the region.

The watershed context

The Central Assiniboine - Cypress watershed encapsulates a landscape that experiences the distinct rhythms of Prairie hydrology. Spring snowmelt floods serve as a defining phenomenon here, shaping the flow patterns of local rivers and streams, including the Assiniboine. Following this spring surge, the river generally sees a steady decline through the summer months due to ongoing evaporation and reduced inflows. This seasonal cycle not only impacts the water levels in the river but also affects the habitats that depend on its resources.

The Assiniboine River at Brandon is well-connected to other significant waterways, including its peers, the Assiniboine River at Brandon 1st Street and near Holland. This network of rivers contributes to the ecological diversity in the area and supports a variety of activities ranging from agriculture to fishing and water-based recreation.

Why the data matters here

Today’s water level reading at the Assiniboine River at Brandon is a critical indicator of current conditions, especially when compared to the median for this calendar day in the station’s historical record, which spans more than 11 years. This comparison allows local residents, farmers, and flood-watchers to understand whether today's level is typical for this time of year or if it signifies potential concerns. Managed by Water Survey of Canada, this data is instrumental in informing decisions around water use, flood preparedness, and ecological protection in the region. Understanding these metrics helps the community respond effectively to the dynamic conditions of the Assiniboine 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.
