The reservoir I live Om has a long aerator pipe system that bubbles all along the pipe but in places bubbles more forming a wider range of bubbling water. Lots of baitfish. The oxygen is like crack to them. One spot along that line holds huge bass and when they are actively feeding I can pull out six to eight pounders on a regular basis using white 3/8oz spinner baits. Just yesterday, using a Zara Spook I landed a 9lb 10ozer. This is usually better in the fall just before Sunset.
