The only swim area's you can't fish are ones that are marked by bouy's with permits on them...A home owner can not make up his own swim area and keep people out of that section of the water unless its approved by the DEP. If that were the case ...anyone owning a home on a lake can mark the whole lake off as thier personal swim area and thats not how it goes.These are public waters!! Those markers on Gardner you were referring to are now marked right and most of that shoreline was opened up to fishing again.
