In 2011, southern
Manitoba experienced
widespread flooding
and Lake Manitoba
experienced excessively
high inflows through
the Waterhen River,
Whitemud River, and the Portage Diversion. Construction of
the Lake Manitoba and Lake St. Martin Outlet Channels Project
(Outlet Channels Project) will enhance flood protection to the
surrounding area and help to strengthen Manitoba’s existing
network of flood mitigation infrastructure. The $600 million flood
protection Project consists of a 24.6 kilometre (km) long channel
from Lake Manitoba and a 23.6 km long channel from Lake St.
Martin. The Lake Manitoba outlet channel includes an inlet at
Lake Manitoba and outlet at Lake St. Martin, a new water control
structure with a bridge and three new bridge crossings over the
outlet channel. The Lake St. Martin outlet channel includes an
inlet at Lake St. Martin and outlet at Lake Winnipeg, a new water
control structure with a bridge, as well as the necessary Manitoba
Hydro infrastructure to power the control structure.

The Springbank Off-stream reservoir represents the
Government of Alberta’s solution to mitigate severe flooding
along the Elbow River, like what took place in June of 2013.
Current plans call for a dry reservoir with a capacity of 70.2
million cubic metres, with an outlet structure to safely release
the water back to the river when safe to do so. The reservoir
will be located approximately 15 kilometres west of the City of
Calgary. In October 2021 voluntary agreements were reached
with landowners to secure the 3,700 acres of land needed for
the project. The tendering process for construction has begun,
with tenders sent to pre-qualified bidders. Construction is
slated to begin in early 2022. Alberta Environment and Parks
will be responsible for the operation of the project once
construction is complete.
