Charters have been baffled on the salmon all season. If you look at the tournament results you would see the numbers and size have been very sub par. Many say its too much bait , others say its due to the 100 year record lake freeze and no thermocline being established .
On the flip side:
Charters have abandoned the search for salmon ( mature ) which is why most hire them and started targeting browns and lakers to put clients on rods. They are easy targets and easily caught, hence you see them on their websites.
Everyone knows this is not a good thing as they can easily be over fished , think of a great perch lake during ice season.
In the next few weeks the mystery of where are the kings will be solved. BTW, I have not seen a coho caught ( from lake reports ) yet.
A good place to research the lake fishery is

Hope this answers some questions
