Hmmm... Remove an unused dam on a creek in May, and a train wrecks on a downstream bridge over the creek in December... Crews were scrambling on Friday to clean up the scene of the latest train derailment...on Canadian Pacifics main line through Banff National Park...The spilled ash and grain each pose their own potential problems for wildlife, one that could lower acidity levels for aquatic life, another that could attract bears to unsafe territory...Fifteen Canadian Pacific cars loaded with lentils and fly ash – a component of cement and a byproduct of coal-fired plants – fell off the tracks on a bridge crossing over 40 Mile Creek near Banff townsite at 2 am Friday. Seven rail cars fell into the creek spilling some of their contents, which turned the water into a murky color...about 200 meters upstream of the Bow River (calgaryherald/news/local-news/transportation-safety-board-investigates-train-derailment-near-banff). The 40 Mile Creek Dam once supplied Banff with drinking water and water to fight fires...It was built in 1946, but hadnt been used as a water source since the mid-1980s...[The May 2014 dam decommissioning] project involved a partial removal of the dam structure, to allow the water to flow freely...It was a joint project by the Town of Banff and Parks Canada with funding from the Province of Alberta: banff.ca/40milecreek (https://youtube/watch?v=5rtbTKUWsFI).
