Brad, My experience with algae blooms mirrors yours but how does this position bass (especially smallmouth). Do they ignore the bloom and position themselves as if it weren't there or do they use the bloom as an "edge" and position themselves in the clear water below and feed against the bloom edge. This probably has more to do with the positioning of their prey or do they change prey from minnows in shallow depths to crayfish below the bloom? Unlike a mud line, an algae bloom will last quite a long time and cover an entire lake leaving the bass no choice but to deal with it.
Would crankbaits fished just below the bloom or along the bottom be more effective than topwater lures or plastics swimming through the algae? Would you go to a bottom lure such as a jig, worm or tube? Would a darker color be more effective than a lighter color in this darker environment?
I know the bass can't climb out and walk to a clearer lake but they seem to change their familiar habits when a heavy bloom arrives... and its frustrating the h*ll out of me! Thanks for any "light" you can shine on this subject.
