ND Otters?

[LBrandt]

Otters are the clowns of the animal world. I could set and watch them all day, but if cornered they can and will get nasty.

I see this topic is 9 years old but wondering if anyone has been seeing Otters in the Devils Lake basin ?
I sure thought I'd know the difference between a Mink and an otter but I'm not sure what I watched off and on for 2 days . At first I just assumed it was a dandy big male Mink but the more I saw of him the more I thought it looked too big for a Mink . He was coming up from under a big dead standing tree on the ice close to 100 yards away and eating fish. Then he would swim about 200 yards from there and come up a hole out in a hole in the ice and I assume eating fish there too, back and forth off and on for two days but it never got up and walked saw it stand once and turn around but mostly hung low and laid on it's belly. It drove me nuts that I didn't have my binos. He was a fishing machine .

I know they are in the Turtle Mountains , same with Pine martins and fishers.
