BBC News - Canada floods: Three killed as waters threaten Calgary

Awful news and I know of at least one poster on here that lives there (hope you are OK). Have managed to contact all most of my friends over there and only one has been affected so far.

I hear that even Medicine Hat has been hit.

I know a lot of you Army lot spend time over there and thought some would like to know how bad it is.

My thoughts are with friends who are affected - it looks like they've lost their home.

Apparently the water is up as high as the twelfth row of seats inside the Saddle Dome, that's where the executive boxes are so they may get their arses wet when the stadium is reopened for the Stampede. LOL

Seriously though, the last time they had a major flood in Calgary was in 2005 but this one makes that look like a damp day in April. It's all over the news here 24/7. I'm glad I live in SW Ontario at a height of 500 metres above sea level. We only have to deal with humidity as a result of living in The Great Lakes basin. Speakin' of which, it's supposed to be up in the mid 30'sC with the humidity making it feel like the mid 40's next week. Thank God for a/c

I'm good thanks mate. Our gaff is on the ridge way above the river in our town. We've got a family of our friends affected by the floods in town staying at ours while we're out of town.

Here's whats left of the railway bridge in town. They destroyed the span in a controlled manner as the foundations have been weakened.

I'm down in Idaho where mrs T_SG is doing the ironman triathlon so missed it all. Had a bunch of calls asking me to go into work and I've heard of blokes working 41 of 44 hours.

The town of high river has, by all accounts, been pretty much wiped out.

Floods are a mongrel of a thing. Here's some shots of my home town at the start of the year. The worst floods in years.

The pub pictured is where my little lady and I stay when we are in town. There's a motel section just on the other side of the picture where I took a couple of snaps for the self taken thread. In the aerial shot, the submerged island can clearly be seen left of the bridge. The pub is to the right of the island. Funny how I only mentioned this flood yesterday....

Stay safe people!

Just on the news here, Medicine Hat has had a bit of a reprieve in that the waters are now not due to hit there until Monday morning, at which time they expect to see 6000 cubic metres/second flowing down the river. When that hits there'll be a sh!tload of damage but at least the delay has given them the chance to build up some sort of sandbag defences around some of the city.

Bone question - is this purely from rain or something else (melt off from the mountains, buggered dam, etc etc)

Rain on top of the melt run off from the Rockies.

And before anyone starts up with Climate Change - the only reason this is news is because Calgary and the surrounding areas are, in terms of history, very new to the area. Before any big floods would not have had much to destroy.

This is one of those one and hundred years event. It's going to happen but its frequency is not regular enough to register.

I think that attitude is part of the problem. The fact is that although it's true that cases of flooding as bad as this are rare, the area does have a history of minor flooding, due to spring run off, so people become used to the idea that there could be a little bit of flooding and so don't take it very seriously. The last major one they had was back in 2005 so they likely reckoned they wouldn't have another like that for perhaps 50yrs or so. WRONG, here we are 8 yrs later and "Holy Sh!t where did that come from!"

L.A used to have similar floods then they got smart and built a huge drainage system and diverted the river through it.That's the huge concrete ditch you often see on car chases through LA in the movies.

It could be that it's time the city of Calgary and elsewhere along Alberta's river systems consider doing something similar. I guess they'd need help from the province and perhaps the federal government but hey, what's all that oil money there for. If, like in L A, it's only needed to prevent things like this once in a while, surely it would be worth it when compared to what this flood is costing the city, the province the insurance companies (for those with flood insurance) and most of all, the people.

They did the same thing in Winterpeg with "Duff's Ditch", the Red River Floodway. Used more than 20 times since its completion in 1968, the consensus estimate is that it has save Manitoba more than $10billion in damage.

But since it's Calgary, they have two rivers to deal with, and that's a solution that's far above my payrate and education.

The winds normally blow from west to east, and drop their rain on the west side of the Rocky Mountains. As a result, southern Alberta is normally considered to be dry by Canadian standards, and BC is very wet.

At the moment, the winds are unusually blowing from east to west, and dropping their rain on the east side of the Rockies, and the water is flowing down the rivers through Calgary (and other towns). There is also another weather system to the north which is keeping the rain stuck in one place in the mountains to the west of Calgary. In addition, the rain is causing snow high in the mountains to melt. Whether this is due to climate change, nobody knows at present.

What we do know is that there was also a flood in 2005 (although not as bad), which resulted in an investigation into what went wrong. The most important recommendations were ignored, because nobody expected it to happen again. The biggest recommendation was to not build houses in a flood plain. However, property developers pretty much run Calgary and they like to build houses on cheap flood plain land with "scenic views" (presumably of the landscape going by as your house drifts down the river). There has been a huge building boom in Calgary in recent years, due to the oil industry. This means there are a lot of houses now where there weren't any before, and lots of people who need to buy houses.

I live elsewhere in Canada, and in the 19th and early 20th century the city that I live in had chronic floods. In the late 1940s they expropriated all the property in the flood plains and tore down the houses and turned the areas into parks. Now, the river still floods in spring, but it doesn't cause any serious problems. And we have some very lovely parks that extend right across the city.

Spring floods are a normal event in Canada, when the snow melts in a big rush (around the end of March in the southern parts). The weather can change very rapidly here. Most cities avoid problems by controlling where development occurs. In Alberta, part of the problem is due to some very extreme weather, but some of it is also self inflicted.

Winnipeg is built at the junction of the Red and the Assiniboine rivers. Due to the unusual geography and geological history of the Red River, the valley is prone to flooding in spring. Many of the smaller towns in the Red River valley have dikes around them. When the floods come in spring, they close the dikes and the town ends up as a island until the floods recede.

Calgary’s problems are somewhat different, so a floodway is probably not the right solution for them.

Bloody hell spent nearly 3 years working in Canada, love Calgary and Canmore, emailed a few friends in Canmore had 1 reply the houses along the Bow are severely damaged, the Bow is a fast flowing River at the best of times, and the gorge it goes down is high and tight in places, really feel for the people down there.

thoughts are to my friends out there,

Medicine hat they have just rebuilt the bridge by the power station, some of it is high ground, the area round the golf course and the valley and train station must be bracing itself,

They have the Elbow and the Bow river's I believe but the Elbow is North of Calgary and runs into the Bow before that river hits calgary. I don't think they have to build a gert big ditch along the full length of The Bow, just the part that runs through Calgary and then the part that runs through Medicine Hat and Lethbridge after the Bow meets up with the Old Man River and changes into the South Saskatchewan. once it's past those area's it's mostly open plains and a bit further east it becomes Saskatchewan's problem, with cities like Saskatoon bearing the brunt of it.
