The boundry is marked on both sides of the river 400' below the falls. The river is closed from 400' below the falls to above the coffer dam. On the west side of the river there are signs on the trail and a cable that runs over the side of the canyon all the way to the river. On the east side unless you are a rock climber you cannot get to the deadline from the trail on Indian Cabin road. If you were between the falls and the coffer dam you are lucky you only got a citation. Advise when you go to court tell the judge you have never fished there before and thought you were in the right place, and that it will never happen again. Or tell the judge that you are a member of the lickapoo tribe and that he has no jurisdiction in this case and you want it moved to tribal court. On the serious side bummer, you should know where your fishing cause they have no sense of humor when you violate the law, remember those wardens have to watch the indians snag from the top of the fish ladder and cant even write them a ticket.
