THIN ICE ADVISORY ISSUED FOR SOUTHERN MANITOBA
A thin ice advisory for rivers and lakes in southern Manitoba has
been issued and is expected to remain in effect until
Manitoba Water Stewardship advises that, while most rivers and
lakes in southern Manitoba are frozen over, ice is very thin and
larger rivers still have open water in some areas.
· Snowmobilers, skiers and others are advised not to
venture onto rivers and lakes due to the danger of falling
· Recent mild weather is weakening ice.
· Thin ice is often covered by snow which produces weak
spots due to its insulating effect.
· Areas of fast-flowing water tend to have thin ice which
may not be visible.
· Ice conditions on the Assiniboine River may be
dangerous from now through mid-January due to rising levels
resulting from increased Shellmouth Reservoir outflows.
· River levels will rise three feet from Shellmouth to
Millwood and between one and two feet from Brandon to Headingley.
· The winter operation plan for the reservoir was
prepared in consultation with the Shellmouth Reservoir Regulation
Flood advisories for the Fairford and Dauphin rivers remain in
effect due to the possibility of frazil ice jams occurring before
The flood advisory for the Waterhen River was cancelled in late
November when the river became frozen over. The Amphibex
icebreaker was used successfully in November to break ice jams on
the Waterhen River.
Levels of the Red River and rivers other than the Assiniboine in
southern Manitoba are not expected to change much during the rest
of this winter.
