And if we can't slow this cart down, I may have to sell my house. The cart, of course, is the massive load of mitigations that we all know must be done if High River is to remain in any state. The horse is the labor required to pull this load properly and in the right direction. That horse (we'll name him "Informed Decision-Making") in this case should be built upon science, study, experience. But gravity is ramming that cart up that horse's rear. The gravity of the situation is that there is massive pressure on government and elected officials to do something, anything, to show that High River will still be standing when the next flood season ends. Gravity is pushing us downhill. If we can't sort out some way of getting this horse back in charge, we're in serious trouble. Above you see the latest recommendations from Town Council sent to the provincial government asking for money to do it. Your legend: Navy Blue is a berm. Yellow is a reinforced embankment/berm. Cyan is a dike. Fuschia is a dike. Green is a dike. Orange is a dike. White is the Little Bow Canal.
Let's analyze this, shall we? If you put a wall up that is perpendicular to the flow of water, that water will stop, spread, and go around it if possible. That's the blue line. So if enough water comes up against that blue berm, it will spill around to the north into Riverside where, because there's a yellow berm in the way, it will have nowhere to drain. It will continue to pool up into a new lake, and my home would be in the middle of it. The second they approve this is the second I put my home up for sale. But I will not be able to sell it, because anyone with half a brain will be able to figure out that I'm trying to sell a 3-season houseboat. Further, the blue berm doesn't take into account the fact that the Town has been working on a development encircling the northwest corner of town called "Spitzee Crossing". This blue berm will not only pool up into currently existing residential neighbourhoods, but will negate the possibility of developing Spitzee Crossing. Maybe that's the point, as that development has been in the works for over a decade, and has been stalled at every opportunity. The development, for that matter, has purposely avoided and given a great big buffer-zone to the Highwood River. It's one development that might actually make sense after the flood. A further problem with this plan is that it is old. It was presented to the Alberta Government 4 years ago based on 10-year-old flood maps, and rejected. It hasn't changed, it is still built on old flood maps. When we will get the picture? Nothing is the same!!! The Town of High River and the M.D. of Foothills has sunk multitudes of taxpayer dollars into developing a cutting-edge piece of software that helps them plan flood mitigations. Not only does it map where water goes now and where it would go if the flows increased, it also gives planners the opportunity to say "what would happen if we put a berm here or a bridge there," and see the results. But this request was not made in consultation with that software. It was made on old defunct maps. I want to scream "stop being stupid!" It's not the first time since the flood that knee-jerk reactions have cause harmful impacts. A Bow River guide explained to me today that the Highwood River, where it dumps into the Bow River, was crystal clear for the first half of August. On August 18, that changed, and it was black with mud. Just days before, upstream about 20 miles, "scalping" of the riverbanks in High River had begun. Making new berms, making old berms bigger, and making old dikes deeper, have absolutely no impact on flood control. Using old maps to determine solutions to new problems is like trying to install a carburetor on a Chevrolet Volt. That same river guide pointed something out to me today. The Mississippi is relatively straight. Downstream of Calgary the Bow River is straight. The Sheep River is relatively straight. They were made that way by floods. In High River, the Highwood River still "snakes" through town. In town limits alone, it turns 20 times. Why hasn't the flood straightened it out? Because it hasn't been a fast and powerful flood. It certainly got to High River in a hurry, but once there, it was stopped up, and so the flow wasn't fast enough to actually allow the river to cut a straight line. This has to have happened in every flood for decades, or else the river would be straight today. So what has existed for decades that has stopped that river up? Bridges. The first one; a railroad bridge whose efficacy at blocking the river is enhanced by a road bridge. That bridge causes the water to back up and spill into downtown every time a few trees gets caught on it. The second one; a new bridge on the Tongue Creek extension known to many as the George Groeneveld bridge. While its impact wasn't as significant, it definitely causes some backup when debris hits it. The third one is east of Aldersyde, where Highway 2 goes over the Highwood River. It got heavily backed up by debris, so much so that it spilled back into the east side of High River. Bridges act as bottlenecks in the first place. When those bottlenecks get plugged, the water pools back, affecting everything upstream. If there is an immediate solution that will alleviate issues, it is to fix the bridges. In the case of the rail bridge, get rid of it, it's not even in use anymore. The centre-street road bridge, it needs to be a four-lane road anyway, so raise it up and make it longer. The Highway 2 bridge by Aldersyde needs to be raised and widened so that debris cannot get hung up on it as easily. If you give the water a place to go without bottlenecks, floods are far less likely to be as devastating. If you berm it in and try to "stop" the water from going somewhere, Mother Nature will just laugh at you as she bulldozes your berm with thousands of cubic meters of water. Now I'm not the most brilliant hydrologist in the world, but even a layman like me can figure out what's going to happen here. And the horse is starting to get scared.
