Fancy,
Looks like you still have lots of water...that certainly is a good sign for your pond in one of the worst droughts in the history of Texas. Did you happen to notice any dead Tilapia? If you saw some and they were only very large Tilapia, then that is an indicator of a healthy predator population (LMB or others). If you see lots of small dead Tilapia, then you probably do not have enough fish predators(again speaking of LMB or whatever predator you prefer).
