April 14 – On this day in Montana history in 1908 the first Hauser Dam on the Missouri River just south of Helena failed washing away homes, buildings and cattle downstream, but miraculously causing no deaths – thanks to heroic efforts to warn people to get to hire ground. The dam had been completed only a year before and was one of the first to be built primarily of steel and was thought to be one of the strongest dams ever built at the time.
