Clear water is tough, I generally fish it one week a year fourteen plus hours a day and still can only figure out the basics. Sometimes it is a soft bait bite and only certain colors and presentations. Sometimes if is a spinnerbait bite when I score high double figures one year to come back the next and not be able to buy a pattern on one. Last year was a squarebill bite, and about the only predictable thing that happened was I needed to switch from an aggressive squarebill to a subtle one after a front moved through. I fully expect this bite to not be there this year.
Moral to the story if you know fish are there, throw the kitchen sink at them, these fish can be insanely picky at times. In these scenarios I may toss 2 or 3 baits at a spot before moving on. It is possible to pattern the fish if you fish often, but even weekend to weekend I could see being really tough.
