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.
Water and Me 
I was stationed at Bainbridge when Agnes came through (didn’t even know it was coming because I lived off the base and only had a radio and only listened to a top 10 station and being a newlywed (well, you know!) the weather wasn’t my main subject at the time. it was pretty bad … the trees were bending horizontal and a few days later we went to the Churchville drive-in and we were watching a movie when someone came over the intercom and announced that they have received word that the Conowingo Dam was about to break. my wife and I didn’t have to worry because we lived on Pulaski Hwy. between Havre de Grace and the old Ames store. luckily for anyone who was in harms way that God was good to them.
Thanks for sharing. I always enjoy a personal account of events instead of what you read in history books or are told by the news media. I was camping up at Prettyboy, chased out and then hung out in Herring Run Park – I think?! The 70s are a blurrrr…
