Springbank Dam is not the right answer to Calgary's flood risk. It will not be faster. It will not be cheaper. And it simply will not protect enough people. 


The Government of Alberta quietly released the full project description of the Springbank Dam. Hidden deep in the document are very real health risks to Springbank and west Calgary including air borne contaminants and changes to local ground water. Here’s one excerpt to be aware of:

“After the floodwaters have been released, the sediments remaining in the Off-stream Storage Reservoir, including on Springbank Road, would dry and be susceptible to wind erosion. Potential contaminants picked up by the floodwaters (e.g., raw sewage) would likely remain in the sediment left behind, and may be picked up and carried by the wind as well.”
