Hate to tell you this bud but the deep bite is best during the middle of the day.
This is not a new pattern. It has been this way for the past 30 years. Not saying you can't catch them early in the morning or late in the day but mid day to mid afternoon, in the hottest part of the day has always been best for numbers of good fish on Fork.
Every time I run into someone that has landed a true Giant at Fork I always ask what time they caught the fish. Almost without fail it is between noon and 5 pm.
Don't bother asking where or what they caught it on, they will lie about that!
