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 Lake Winnipeg
Lake Winnipeg - a vast water body in the heart of Manitoba.
Lake Winnipeg stands as one of the largest lakes in Canada, playing a vital role within the Prairie hydrology of Manitoba. This extensive body of water is part of the Lake Winnipeg watershed and serves as a significant feature in the regional landscape.
The watershed context
The Lake Winnipeg watershed encompasses an impressive catchment area of roughly 970,000 square kilometres, draining a diverse array of rivers and streams. Although no specific peers are identified for the lake, its expansive size and hydrological importance make it a central feature of the region. The seasonal patterns in Manitoba reflect the influence of spring snowmelt, which can lead to significant flooding events, particularly in the Assiniboine and Red River basins. As summer unfolds, the lake typically experiences a natural recession, marked by decreasing water levels from evaporation and reduced inflow. This cyclical rhythm is critical for understanding the hydrology of Lake Winnipeg and its surrounding ecosystems.
Why the data matters here
At the station "Lake Winnipeg at Gimli," real-time data helps inform cottagers, anglers, and the wider community about current water levels. Although this gauge does not measure discharge, monitoring the lake's elevation is essential for flood management and resource planning. Today’s reading will offer an informative perspective on the lake’s current status compared to the historical median for this calendar day, with data spanning over 15 years from the Water Survey of Canada. This contextual comparison is invaluable—it helps stakeholders gauge lake conditions and anticipate possible flooding or water quality changes affecting local activities and ecosystems.
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.
