It depends on three variables. What is the visibility the bass are accustomed to, the degree of stain and what is the main forage. If the bass are used to 20 foot visibility, and now it is four than they will react differently than if the vis. is always 4 foot. If the bass are used to feeding on open water bait schools and the visibility drops to 2 foot, than they may have to change their diet, which in turn makes the bass change their location. If the vis. is always the same, than the forage will remain the same. My best big bass lake has 1.5 foot of visibility October - mid July. The water temp. only varies a few degrees during this time, and all lures are on the table. Top water works best, until the water level drops and the bass are forced it to deeper water, and crankbaits take over the top spot.
When the rain comes the water visibility goes to less than a foot. The first couple weeks with this poor visibility the fish move close to cover, and all moving baits quit working. I have to pitch jigs, and plastics right in their face and work slowly. Not my strength, but my only other choice is to stay home. Once the fish get used to the poor visibility the top water bite starts to work again, especially buzz baits, and popping frogs, as well as spinnerbaits, square bills, and swimbaits. This pattern works for the remainder of rainy season.
Another lake I fish the visibility is always less than a foot, and the bass there are caught all year everywhere with everything. From rocks, to punching mats, and even out in the open chasing bait.
I prefer two to 6 foot of vis for bass fishing. This visibility gives me the most options with location and gear. Less than two foot, and I may have to slow down, more than 6 foot, and I may have to lean toward finesse techniques. That is only what I prefer. The bass don't have a preference, and will manage to find something to eat in 2 inch vis, to 30 foot visibility without any problems.
