Set the cross over on the dam , set both side but put them on drowning rods that way when it's caught it's down in the deep part and won't spook other beavers . Set the deep side with a foothold on a drowning rod then the shallow side with a conibears but put enough wire on it for it to get away from the cross over . A beaver will get educated quick if you're using conibears and they get smacked and not caught . I have been in a few places after a trapper has been in there only using conibears and they only made them smarter ,they become square shy .
