Thanks Maxx-7D. Our communities are fine, but it is heart breaking. I'd guess damage will be several billion
dollars. Off topic.
We are 2½ hours from Calgary (Bow River) in a different river drainage (Oldman)..and we are 15 minutes away from the Oldman River that is in a deep valley. But we had 4 to 5 inches of rain in our area this week. Our subdivision is on an old lake bottom with heavy clay and water does not drain well here...our backyard drains poorly. Never had a probelm before.
We are away from the huge areas where destruction is unbelievable.
The reality is we build cities and towns in flood plains that formed over the past 10,000 years since the end of the last glaciation. See this
graphic of Calgary showing all of the affected areas. (We live east of Lethbridge shown in the inset.) ALL are adjacent to the two rivers. No one knows how often the rivers flood like this because there are no records that pre-date development and population growth. Calgary at over one million people is really only 100 years old...no centuries of experience here.
But there is powerful evidence that the areas are vulnerable because of the structure of the valleys and flood plains. Yet we build in the areas that get flooded now and then and forget history. See here
. This is the city near where I live...fortunately there is little development in this valley.
Sorry for the off topic editorial. Thanks for your comments Maxx-7D. We are forunate to be doing well.
