This is Bloede’s Dam as it appeared in late Fall of 2003. Just left of center upstream from the dam you can see a thick-ish, overhanging tree at the river’s edge. I would almost drown there in March of the following year only twenty feet from the bank.
The following is from Wikipedia:
Bloede’s Dam was a hydroelectric dam on the Patapsco River in Maryland. It was the first known instance of a submerged hydroelectric plant, where the power plant was actually housed under the spillway. It is also recognized as one of the earliest dams constructed of reinforced concrete. This area is now part of Patapsco Valley State Park Avalon Area.
I haven’t been back to Patapsco Valley State Park since 2004 and this may be the last picture of it I’ll ever get to take. According to the Wikipedia article, it was due to be demolished in 2016-2017.
