Alphadog in some places that works well in a residential setting but out on open range not so much flooding and land erosion or ever widening swamp or bogs can become a problem .
Also if you have enough 4" S & D perforated pipe you can lay it on the bottom of the creek and through culvert \ bridge well above or upstream of the crossing the beaver may try to plug the culvert without any success .
I once found a beaver killed whitetail buck , it was crossing the creek during a wind storm and a aspen that a beaver was chewing on and quit before it fell snapped hitting the buck pinning it down in the water where it drown with a possible broken back .
I used to have pictures of this but a mad now exwife destroyed them . but not my memory ha ha !
