I don't fish but bought the property for privacy, nature, the view etc.. I actually want people to fish sometime for the health of the pond but on my terms. The 2 acre pond is essentiall my front yard and most of the time we don't want to see anybody in our front yard. We've bought many trees to block our view of other houses, people etc.. My neighbor who actually lives closer to the pond than me wants unlimited access but I will not let him fish if he doesn't call/ask. He always wanted to trim around the pond etc.. but I found everytime we went to the property, he and his wife were sitting around the pond fishing,smoking and drinking. I couldn't take it anymore so I lost my temper and cut him off unless he asks. He hasn't asked yet. BTW, we are building our house and won't move in for another couple of months.
At this stage of my life, privacy is at a premium. We're moving 45 miles from work just to get away. The neighbor insist he will still trim the pond even tho he knows he can't fish...He hasn't trimmed it yet. Fortunately, our property sits up off the road and a person would have to be fairly bold to sneak in to fish. Also, I can show up at any time of day or night.
The only thing i worry about is someone sabotaging the pond; like putting washing powder, clorox etc. in the pond for spite.
