Please explain???
"But if you hook multiple chum and the officer feels you are fishing water holding chum he may write a ticket."
Well its pretty obvious thats not going to happen a)no officer is going to stay there to watch one fisherman in specific b) the river is still open for Chinook and Coho retention and you can catch chums in the mix on any part of the river and c)You cant change up your baits to try and avoid catching chums because they will take everything that the open species will take.
"It may be wise to avoid waters with lots of chum as the vedder seems to be specially regarded as it is the only one I know of that has no chum fishing stated and they very well might enforce that rule in areas."
Do you have an inside tip that we don't? They stated in the fishery notice it is closed for retention until the end of the year, they arent going to make a special regulation to close areas of the Vedder to avoid chums because like I said above you can catch chums in any water on the river. It;s just common sense.
