View information on water levels and related weather conditions around the province. Go to the Hydrological Data application.
The readings are displayed graphically in charts and can also be downloaded in Microsoft Excel spreadsheets. Data are presented in metric.
The near real-time information presented on this website is received via satellite or land-line transmissions from hydrometric gauging stations managed by Manitoba Hydro, Water Survey of Canada, and Manitoba Water Stewardship. The name of the station operator is displayed in the station detail page.
This website is updated daily.
(In the application, click on one of these links, or on a gauging station (coloured dot) to find out which measurements are collected at that station.)

Weather conditions, such as wind and barometric pressure, can cause water levels to differ substantially at various points on Lake Winnipeg.
In order to determine the average level of the lake at a given point in time, a smoothed wind-eliminated level is determined. The regulation of the lake is based upon this wind-eliminated level.
Water levels are recorded continuously at 8 water level gauges around the lake and it is from these levels that the wind-eliminated level is calculated.
