i shot 3 in my pond last year in the early spring. i would see them late evening swimming around usually carrying reeds. i walked up on one boring a hole in the bank. he was kickiing up all sorts of muddy water. i knew he couldnt stay under forever. sure enough he finally came up and went swimming along the edge. it's the otters that worry me. i have caught 2 in the last 2 years ( one each year) below my pond while trapping beavers. i caught them on dam crossovers in 330 conibears.
