dogpound - Sorry, no. My neighbor said his grandfather had been a hoarder since the Great Depression, so I guess anytime between then and the 80's when he died. Again I apologize, that's a pretty big window and I'm sure it doesn't help.
thanks, i was just curious because the resevoir was created in 1975 so anything buried or hidden in that area pryer to that time could have been moved or under the lake
