How Would You Fish This?

I frequently fish this river channel connecting the Red and Mississippi Rivers. The channel is about 5 miles long, 1/4 mile wide, and snakes a couple times left and right. About a mile before the lock, the channel splits into two seperate channels... one ending up against a levee and the other going through the lock. I have GREAT days here during the summer when the water level is normal. However, I tend to struggle during the prespawn (Such as now). I am unsure as to why this is the case as I feel as if i understand pre spawning bass well and have success this time of year on other lakes. Could it be that the bass have moved out of the area entirely? Or, probably most likely, is the high river water hurting my chances that much. I tend to believe that it may be a bit of both... Therefore, i present this question to all:

How do you fish the aforementioned river channel at this time of year when the water is high and "in the trees"? There are various sand bars and many willow trees which are now flooded. There is also a couple rock jetties, one of which stretches across the entire channel. I do not need to hear that i should go elsewhere as i absolutely accept the great challenge of fishing high rivers. This time of the year is the only time i struggle in this location and i want to figure this out. (BTW... I will be there in the morning and will try any tips posted as well as provide feedback)

Safe fishing to everyone and good luck this year!
