The 4 days were actually Wednesdays for a few years making it a little more difficult for a working man to get out there and hunt.Major changes to the games laws were enacted when hunting resumed including prohibitions on shooting does and fawns. The months long open season was also shortened to just 4 days.
There was a sawmill erected just upstream from where the dam is now. That was probably the only reason it looked like the regular dam was there in the earliest years. When the lake was drained they saw some timbers and whatnot showing where it was. I think it describes this in John Pearce's Heart of the Pines.
Bob, sorry I should have been more specific. The race I was referring to was the one that can be seen on the c1890 Cook topo.
Do you have more information about it?
Scott, they didn't know any better back then. They thought the game would be infinite. It's disgusting how many shore birds and hawks and ducks they killed back then. There was a slaughter every year in Cape May County.
