Hey Brendon , glad you’re still around. Otters were stocked on the middle Fork of the Vermilion River. They have moved up and down the salt Fork and I have wiped out all the small mouths on some of the small spawning creeks. last year on the salt Fork was the worst. I can remember in 30 years. Not sure if it was Otters are just a down year. I have heard stories of people that had small ponds above the creeks, and the otters would go into the pond and completely wipe out the fish population. I did not do as much river fishing here locally last year I will try to get out more this year and let you know when I find out. Thanks again and good to hear from you.
