So what I found this morning is that all of the streams and creeks around York have drastically changed since the construction of Indian Rock Dam. This Dam prevented many many floods after its construction. The city of York flooded approx 17 times before it was constructed! I think I found some more hints to where this occurred, I may do a drive by today to see if it is accessible..
Some of it may be underground.
In the town of tremont there was a run of water called Poplar Run in the 1870's .
at some point they Built a Tunnel for the water to Flow to the creek.
it only Burst through with a Flood in 2011
I'm sure not every Village used tunnels, But
you may want to see if there are old maps of the area
