Ive been asked to trap a colony of beaver on a very small creek.the problem it's quite a drive to get to it.whats the best way to go in and trap them quickly so I don't have to make multiple trips to this location.any suggestions would be appreciated.

Those jobs I set real heavy, prefer not to use many scent mounds but blind sets. Not sure what your thinking is far, but I have a job to start a little over an hour and a half away, I charge by the trip, and I charge a lot! I could be catching damage beaver closer so you have to.

My guess you are getting some ice now? If you have open water set every bit of sign there is. Dam cross overs any trails to feeding areas and in and out of lodge.

Personally, I would also set all sign, however I would not set lodge/bank den entrances on first sets. You are likely to catch a beaver there first and put the rest of the colony on high alert, even holing up.
And the further from the den you are setting, the more likely it is you will get the older beaver.
I wouldn't be shy about using castor mounds at your furthest sets. And if you find where they are logging and getting material for the feed bed, that is where I would put as many sets as sign calls for.
After you have taken the adults and hopefully a couple teenagers, then set the den entrance(s).
It is unlikely you will get the entire colony in one check.

Yes good point.
