Salmon are aggressive feeders at t dusk and dawn. You can get more action in the 30 minutes before and after sunrise than between 7 and noon. The magic hour of dawn and / or dusk when the skitters come out is when many species of fish check in at the buffet. Salmon are very light sensitive. Once the sun is up they get cautious and go deep to digest the morning meal. As with everything, there are exceptions - days where the lake is on fire, or in the case of a morning after a full moon in a cloudless sky, days where the bite doesn't turn on till later in the day. Once you've had a sunrise screamer on two or more rods at the same time, the addiction is set.
