With over 1000 trees marked throughout the Mississippi-Eastern Louisiana river deltas and basins I have learned one MAJOR thing, not all structure recruits Crappie. Stuff you would think held fish all the time never produces a Crappie. Catfish, Goo, other Panfish, even Gar but no Crappie. If I had the answer to why I think it works that way it would be material for a book. So that statement of Fact behind us, then as a troubleshooter by nature you divide and conquer! Once locating and marking structure you have to see if the newly found structure recruits Crappie. Some tidal spots recruit on a seasonal basis, some hold fish year around. Since father time is always working to cut our time short I fish new water like I am Speckled Trout fishing. If I don't get a bite in 2-3 minutes I'm moving to the next marked new structure. If three spots in a row in the same area doesn't produce I move to another area. I divide rivers in half, then half again, till I find productive waters. There are trees marked on my Humminbird that have been reliably recruiting Crappie for 15-20 years, then some that have a few 75% of the time, some a few 50% of the time, if less than 50% of the time I drive by them in the future. You have to fish them all at first. Time management doing that is my absolute goal working out new water. Now 20 years later I catch fish everyday, I just don't let people know it.
If I die from a Deadly Sin it will be Gluttony!
