More on Flood Protection in Manitoba

By: plapman , 1:09 PM GMT on February 23, 2013

Today will be sunny except cloudy over eastern sections this morning. The high will be -3C(27F). Tonight will start clear but will see increasing cloudiness after midnight. The overnight low will be -12C(10F).
The next layer of defence against the spring runoff is the Portage Diversion.
I started my career with the province of Manitoba in 1968 working on the project.
my job there was to ensure the dykes were compacted to ensure they ere impermeable.
From The Province of Manitoba Website.
Portage Diversion
•This 29 km (18 miles) channel diverts water from the Assiniboine River into Lake Manitoba, just west of Portage la Prairie.
•The removal of up to 25,000 cfs of flood water provides flood protection for the City of Winnipeg and areas along the Assiniboine River and also supports flood protection along the Red River north of Winnipeg.
•The project was built from 1965 to 1970 and cost $20.5 million.
The control structure on the assiniboine River.

The Channel leading to Lake Manitoba

Due to a 50 foot drop in elevation between the river and the lake 2 concrete structures, called gradient control structures, were built to stop erosion of the dyking.

I hope the flood control is able to keep the cabins dry, but you've had a lot of snow this year!

I bet the Diversion would cost a lot more than $20.5 million now! :' )

Hope you're having a good day!

Good morning Tony. Great information on the Diversion.

Temps a bit milder today in the low 30s but at least it's melting the snow we got. Sun is trying to break through the cloud and it is in the forecast for this afternoon. Looks like temps will remain stable for the rest of the week just above freezing here so that is a bit of a comfort. March will soon be here so it will be interesting to see what it brings.

Have a great day dear one.
