That is messed up. I keep my eyes open like a hawk for my people's property and ponds. One time this kid who did not look like he belonged started fishing in one of my gated community ponds. I was finding 40 bottles, drug paraphenalia, a lot of stuff I never saw before. So I decided to check him out. I became his buddy, got all of his info and passed it along to the HOA. Unknown to me there had also been property damage, vandalism and theft. Gated communities in El Dorado Hills just don't have that. He was some oxycontin drug dealer. Got the gate code from the gas man. Needless to say the gas man was read the riot act. The drug dealer was reported to the cops, who had an outstanding warrant and was well known to them. The key to any pond is vigilance. Have everyone who uses it keep thier eyes peeled. How secure is your pond if I may ask?
