Came across this Sun Paper photograph showing, what it says on the back, that all 53 gates of the dam were opened during the storm. It doesn’t look like all 53 are opened. In a 2008 interview, a former Conowingo Employee, Elder Silvercloud tells us that many of the flood gates wouldn’t open. They were stuck. Another article I read said they were going to dynamite a portion of the dam to relieve pressure? In 2011 another storm caused them to open 43 gates. For more info, Google Search Conowingo Dam Agnes.
Notice there are no watermarks saying ebay or sun paper – that is because I do not steal these photos off the internet. They are in my personal collection.
