Recently there has been some confusion about the status of the Chuit (Chuitna) River. The Tyonek Native Corporation did try to get possesion of the river by arguing that it is non-navigable (essentially submerged land, a bog not a river). They obviously had a friend at the BLM who came out and took a look at the 30 foot wide river and said "That's no river."
The owner of the Chuit River Lodge screamed bloody murder and finally enlisted the help of Senator Ted Stevens and suddenly it magically turn back into a river
So for the record the river is NOT closed! Check the Alaska Fish and Game site if in doubt.
