I have had these photos for a while and can not remember who passed them along to me. The first picture appears it was taken from Greenbank Road looking across the Red Clay towards the south end of the bridge in Marshallton. The second is on the old Ametek mill property. That is the concrete bridge crossing the falls at the end of original millrace. You can see in the third photo ( a recent one) how high the water came up. It is obvious the water went over the bridge and Greenbank Road was covered. I can not imagine what downstream was like. You can not tell where the creek is. Documented on the back of one of the older photos is a date of 1938.
Now that this old site (c1765) sits vacant it should be looked at and acquired, from the current owner, by the Federal, State and the County Governments to be used for flood mitigation and recreational purposes like what is being done in Yorklyn and what was done in Glenville.
