A persons property rights end well before thoes rights destroy public resources including fish. No one should have the right to destroy salmon habitat on their private property.. The exsistence of wild fish is more important than individual property rights!

Also note that it is impossible for a single individual to own any surface water.. All streams are owned by the states.. The little creek in your back yard does not belong to you even if the ground under it does and you have no right to destroy it..
