beaver problem

[model 70]

there is this golf course that's being depleted of all it's younger trees by beaver. now on this course there is no pond or damn for the beavers. just a creek that runs through the property, under the paved road and into another piece of property. now i'll be trapping on the golf course and the creek the runs through runs from about 10ft to as little as 2ft across. of course the first thing that popped into my mind was to make a blind channel set where the creek runs under the road and into the course but how do i make this set when the creek is 10ft. wide? thanks for any suggestions.
