There will be a lot of movement going on .If I set up on rivers or creeks,I would leave the sets in. Soon you will have all kinds of movement and travelers.On ponds I set several traps ,so I may pull after 2 or 3 days.I gang set most times,so the bulk of the pond beaver are taken the first night or 2.
I treat big lakes much the same as rivers,my traps may be out for the duration.Here again there is all kinds of beaver movement.
