WOW - stream fishermen may definitely have an advantage here 'cause it's really getting deep and waders may be required from this point on - all living creatures "react" whether this is a voluntary or involuntary response depends on a lot of things. The original question was basically do bass "react" differently in clear water vs. muddy water - I think they have to because some of their processes for detecting what is being presented has declined. If the process was the same, why to almost all Pro's recommend using a more natural colored lure in clear water as opposed to using a brighter (unnatural) color in muddy or stained water. Part of this has to do with sight, of course and the tendency to "react" to something that is "not natural" is greater under those circumstances.
Now for the aggravation reaction - as in all living things - the process for detection begins to shut down and the consequences of the reaction is less "thought out" (no, this does not mean that I think bass are capable of reasoned, rational thought - its just that the input of stimuli is more reactionary). I think the aggravation reaction may be stronger in clear water, because there is more stiumuli being presented over and over (I have heard Pro's talk about making 15 casts to the same spot before getting "a reaction"). In muddy or less clear water it may be more of a startle response (reaction) because all of the senory data isn't there.
