Fished a local lake today - air temp was around 80F and peaked around 93F, whereas water temp was probably high 60s or mid 70s.
I had fished this lake back in end of April and caught several paired up on beds, so I thought today's outing would be strictly summer patterns.
However, today I saw at least four or five separate instances of decent sized bass just cruising in the shallows during the mid-day heat (11am-1pm or so). Each time, the bass were relating to hard cover (next to small piers) or in the shadows right in the bank. One instance, I saw a big bass followed by a smaller bass, but they did not look to be staging for spawn and cruised around then disappeared. Another instance, I saw at least 3 big bass cruising together in the shadows, exhibiting almost carp like behavior and getting their heads up right against the shallows. There was even one instance of a bass just suspended right at the top of the water column 20-30 feet from the bank next to no apparent cover or structure.
For some of these instances, I was able to present a Ned rig, dropshot, and lipless crankbait but they didn't seem interested at all. In some other instances, once the fish spotted me or saw the flash of my cast, they darted off for deeper water. I threw a jerkbait at the bass that was suspended near the surface, and it just seemed to get annoyed and slowly swam out of casting distance, but still visible.
I'm pretty sure these were all bass and not carp based on the dark coloration, shape, and tell-tale stripe.
Question: what phase were these fish in? Is this post-spawn behavior, and the lack of bites a sign of lethargy? Or is it more of a summer pattern that will just require more stealth and long casts in order to be successful at?
