River conditions and forecasts during high water are reported via daily flood sheets
and narrative reports, as explained under the "Forecasts" tab on this website.
However numeric information on river levels and flows is also available from a network of
electronic river gauges operated primarily by Water Survey of Canada with assistance
from Manitoba Water Stewardship and Manitoba Hydro.
Daily Stream Flows:
Manitoba Infrastructure prepares charts and tables of river flows for 21 river locations in
Manitoba for Thursday of each week throughout the year. Weekly river flows are shown on
tables and plots along with the lower decile, median and upper decile computed weekly
flows based on the past 40 years of record. This makes it easy to compare recent river
conditions with averages and relatively extreme values from past years. The river flow
estimates include information from flow measurements, most of which are provided by
Water Survey of Canada. Flow estimates include backwater effects from river ice or debris.
Monthly River Data and Plots:
This monthly or seasonal product provides more abbreviated information about river flows in
Manitoba. It is released when flows are generally deemed to be important for a snapshot
and in case there are some specific requests for river flows data.

Water Survey of Canada Real-time Hydrometric Data
Water Survey of Canada enables a user to select a station from a map or list and to
display charts of recorded water levels for a specified time interval of up to two years.
The site is 'near real time', i.e. the most recent levels are usually only 3 hours old for
many stations and 6 to 12 hours behind present time at other stations. However the site does
not provide forecasts since that is a provincial responsibility. The site also provides water
levels for many lakes and for larger reservoirs. Stations operated by Manitoba
Water Stewardship and Manitoba Hydro are also included on this site.
