Wow, the last two issues mentioned here are very similar to what I've experienced lately. My first issue is the funniest, although it wasn't funny at the time. When I bought my property where my house is, one corner of the property
always stayed wet and there was basically a small stream that ran from the natural spring. To me, that was a logical place for me to put my lake, so I did.
In the year or so it took for my lake to fill up, the property owners down hill from me noticed that the water that had flowed across one part of their property had suddenly quit flowing and they were elated and put up a yard barn on their newly dried out property. As Bob had mentioned, you must direct the water flow back to where it naturally ran. That dictated where my overflow pipe ran; where the natural small stream bed was. Makes perfect sense, right?
I get served with papers from the neighbor suing me for creating water and diverting it onto their property once my lake is full and the water began flowing again!
Although I obviously won the court battle, I'm still seething that I even had to defend myself against such a bogus law suit!
The next issue is with trespassers. On a couple hundred acre piece of property I bought about 20 miles from my house, I had constant problems with trespassers who not only were trespassing, but destroying things and leaving trash. I was going to build a fence all the way down the one side of the property that borders a road, but that would have been over a mile of fence. Instead, I called in a favor from a buddy and used his D6 dozer to dig a "natural" (but deep and steep) ditch all along that side of my property with only one entrance where I put a gate.
I've seen evidence where two people have tried to cross the ditch with their "monster" trucks but didn't make it. I also saw one area that was really a mess. While I was using my tractor to fix that part of a ditch an old guy driving by stopped and told me what happened. Apparently one of the long term trespassers decided to drive his backhoe there and open up a place for him to gain access again to my property. Apparently he screwed up and turned his hoe over into my ditch.
Better yet, a game warden came along to help. The game warden refused the trespasser to call another of his buddies to get his hoe out of my ditch and called in a commercial wrecker. I bet that cost him! It just seems strange that I've never heard from the game warden, the state, nor the guy who was attempting to trespass. Oh well...
