Willand Pond in Dover,nh has blue green algae in it . It's bad too, they shut the whole pond down. I have been fishing in it as well as other places. I want to know if anyone can tell me if I am running the risk of contaminating other ponds. this stuff is nasty. It can make you sick, kill your pets, and destroy the pond. I don't want to spread it to my other fishing spots. please help.
