I have a question concerning ponds in commercial areas. I investigated one outside of my work here in Dublin Ohio. I was spudding through about 4-5 inches of ice and using my spud bar to determine how deep it was. Got deep quick as IT was 9 ft deep 9 ft away from shore. When my spud bar hit bottom, an offal sewage smell came up from the the hole and black water was dripping off my spud bar onto the ice when I brought it up. Is this a fishable pond or just some sewage drain run off that was landscaped and filled with water to look nice?
