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.

Why the Assiniboine floods every spring

Inside the freshet cycle that puts Manitoba shorelines at risk each year - and why 2026 broke the script.

Flash Flood Alley: how Texas rivers rise in hours

Why Central and South Texas rivers go from gravel beds to fifty-year records in an afternoon - including July 2026 on the Nueces.

About Nelson River (east Channel) below Sea River Falls

Nelson River (east Channel) below Sea River Falls - a vital waterway in Manitoba.

The Nelson River flows with significance in Manitoba, particularly below Sea River Falls along the east channel. This stretch is part of the larger Head Nelson watershed, which encompasses a substantial drainage area of approximately 976,000 square kilometres. The river acts as a crucial thoroughfare in the region, supporting various ecological and human communities.

The watershed context

The Head Nelson watershed channels an impressive amount of water from surrounding landscapes, with this segment of the Nelson River not only receiving significant runoff but also being influenced by spring snowmelt in the prairie hydrology of Manitoba. Characteristically, Manitoba experiences impactful spring snowmelt floods, especially evident in river basins like the Assiniboine and Red. In contrast, the summer months typically witness a natural recession as evaporation and lower inflows take effect.

The river corridor is interconnected with other water bodies, notably the Nelson River at Norway House, which underscores the network of ecosystems supported by this flowing water. The dynamics of the river at this station reflect the broader regional patterns—how water moves seasonally through the landscape and influences all that relies on it.

Why the data matters here

Today’s reading from the Nelson River (east Channel) below Sea River Falls is critical for understanding local hydrology. Reporting to the Water Survey of Canada, the data here goes beyond mere elevation figures; it provides context by comparing current water levels to historical median recordings for today’s date. This allows for an understanding of how the current season is behaving relative to typical patterns observed over the past 13 years. Such insights are crucial for local cottagers, anglers, and flood-watchers as they gauge the river's status and potential impacts from seasonal shifts in water flow.

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.
