I was recently involved in one on the Wynoochee where a family trust received 75 acres or something from deceased. The brothers and sisters divided the property evenly and each got 25 Ac+/-.

Then the river changed course and left the one who wanted most of the river frontage (an inside corner) with 7 acres. Property lost 18 acres over the course of a couple winters. She is trying to sue her family to re-adjust the boundaries to be equitable again. What a mess. The lawyers are having fun with it though.
