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.

How snowpack becomes summer water

The science of snow water equivalent and why it drives the season ahead.

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.

South Moose Lake Water Level

Live lake level, flow, historical records and forecast for South Moose Lake in 2-56-18W, MB, Canada, built from official government gauge data.

About South Moose Lake

South Moose Lake - a vital waterway in Manitoba's Moose Lakes region.

South Moose Lake is a significant body of water located in Manitoba, part of the Moose Lakes watershed. With an expansive catchment area of approximately 9,260 square kilometres upstream of the station, this lake supports the local ecosystem and plays a crucial role in regional hydrology.

The watershed context

South Moose Lake is part of the Moose Lakes hydrological system, which includes its peer, North Moose Lake. This region is characterized by a prairie hydrology that is defined by spring snowmelt floods, particularly affecting the Assiniboine and Red basins. During the warm months, the water levels in lakes like South Moose Lake typically experience a natural recession as evaporation takes effect.

Why the data matters here

Understanding water levels in South Moose Lake is essential for those who engage with the water, whether for fishing, recreation, or environmental monitoring. Today's reading, closely monitored by the Water Survey of Canada at the Moose Lake Narrows Control Structure, provides a snapshot of current conditions. Evaluating this reading against the historical median for this date allows for more meaningful context than raw elevation figures alone. With nearly 49 years of recorded data, this lake's measurements inform assessments of seasonal trends and assist in sustainable management practices for the surrounding environment.

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.
