First Provincial Flood Forecast

The first provincial flood forecast of the year is cautiously optimistic. Infrastructure and Transportation Minister Steve Ashton says the preliminary outlook suggests, without additional significant precipitation between now and the spring thaw, the potential for flooding is below or near normal in most areas. He says this is mainly due to near-normal soil moisture content at freeze-up and near-normal water content in the snowpack.

Two areas of concern the province is looking out for are parts of the Souris River basin and regions surrounding The Pas that have an above-average flood potential as the soil moisture content levels at freeze-up varied from above to wellabove normal and the snowpack water content is above to well-above normal, with levels up to 170 percent of normal.

Steve Topping, Executive Director of MIT says icebreakers will focus on the Red, Assiniboine, Icelandic and Fisher rivers, as well as the Portage Diversion. As for the operation of the diversion, he says its will be operational though he is still unsure as to how early in the spring it may happen.

"It's very likely it will be used this year, given the normal and adverse weather scenarios. The Portage Diversion is key in managing ice on the lower Assiniboine between Portage and Winnipeg and normally, its' initial operation has to do with that."


Additional highlights from the flood forecast include:

Rivers

* On major rivers, including the Red and Souris rivers, flows are generally normal or near normal for this time of year.

* Assiniboine River flows are slightly above normal for this time of year due to releases from the Shellmouth Reservoir, which increases its capacity to manage spring run-off.

* Major Interlake rivers, including the Waterhen and Fairford rivers, are above normal due to the consistently high water level of Lake Winnipegosis.


Lakes

Lake Manitoba

* Lake Manitoba's current level is 247.4 meters (811.8 feet), slightly above normal for this time of year but within the operating range of 247 m (810.5 ft.) to 247.7 m (812.5 ft.).

Lake Winnipeg

* Lake Winnipeg's current level is 217.6 m (713.8 ft.), slightly above normal for this time of year.

Lake Winnipegosis

* Lake Winnipegosis is currently at 253.8 m (832.7 ft.), 0.6 m (two feet) above normal for this time of year.



Flood Preparation

The Amphibex icebreakers and ice cutters will be focusing this year's ice-jam-mitigation program on the north Red, Assiniboine, Icelandic, Brokenhead and Fisher rivers, as well as the Portage Diversion, to reduce the potential of ice jams. The Amphibex fleet has already broken a six-kilometre channel down the centre of the Red River and 12 km of ice has been cut.

The chances of minor localized flooding due to snow blockages in drains, ditches and small streams during the early part of the run-off period will be dependent on the nature of the spring breakup and rate of melt.

Good morning Tony. Looks like we are in for a bit more cold weather with possible snow flurries. Damn, I figured by this time we would be into the 50s when I booked my eye surgery a couple of months ago. We will be lucky to reach 35F on Wed when I have to go in. This year has been just nuts. Anyway have a safe and happy day. Stay warm, stay well and keep the great jokes coming. Sometimes its the only thing that makes me smile on these miserable cold days.

Good afternoon Tony. Hope your Sunday proves to be a restful one. Spring is in the air but she sure is taking her time to get her butt up here. Hope you get a chance to go for a nice walk with Abbey and don't forget to give Kramer a nice tummy rub for me.

Have a great week ahead buddy.

Hi Tony, stay safe and no playing by the rivers. I know you like to go and peek as much as anyone else but do so cautiously.

You folks have lots of snow to move so flooding is something to expect. Lets hope it stays to a minimum and you get a slow melt.

Thinking of you buddy. BTW, thanks for those great jokes.

I think the drifts are getting worse there, Tony! All the fodder for the Assiniboine, am I right? :(

Take care!

Tony, this month, instead of three white rabbits, I give you three March hares, because the weather's been mad! :' )

Never thought of icebreakers going up and down rivers; I always thought they were used on oceans amd large lakes. Makes sense though, since the icebreakers keep the water flowing, and limits flooding!

Hope March treats you kind!
