Plymouth Power Plant

I stopped by the Plymouth Nuclear Power Plant Tuesday at noon to cast a fly and was surprised to find the gate leading to the visitor parking lot shut and locked. They didn't lock it for the year until December 1st last year. Has anyone any idea about whether the gate is to stay shut until spring 2001 or was this just an unusual circumstance to have come across. I believe their are new owners of the property. Also I know they were dredging the inside of the southern jetty, and I'm wondering if they have expanded the dredging further necessitating the earlier jetty closure to fishermen/fisherwman, and baitcasters.
