What I've seen in the past you could contact mdwfp and get a permit to have one to control beaver and other animals on your land in the north half of the state. It had to be returned to the state.
Years ago there was one in the spillway channel at Enid. My father-in-law said if it got on his line he would kill it. Mr. Greenjeans said go ahead, you won't see day light for a long while.
You better make some calls to the state before asking us for trouble.
