Well this morning when i looked out the windom expecting to see the fish feeding i wasnt happy to see the otter feeding instead. I grabbed the .223 and snuck down to the pond while he was down. When he finally popped up he was 30 yards from me. Well im hopeing hes dead but he didnt float. After the water settled i watched bubbles come up for 15 or 20 sec. from the spot where i shot and that was it. He never popped back up and he hasnt floated up yet this afternoon. How long does it usually take for one to float back up?
