A common theme when fishing pre spawning bass is going out, catching 20 bass, but having them all range from 12-15 inches. The majority of these bass are the males who venture into the shallows ahead of the females. This year where I live the temperatures have been changing so drastically i feel like the males have been going back and forth from drop offs to the shallows for 2 weeks now. But the near future forecast should have the bass completely on the beds within the week or two.
Targeting the bigger females should consist of the first and second drop offs just behind the spawning areas. Primary and secondary points will still be good targets as well but in this river the first drop off is where the majority of the larger females are hanging around.
The lures i throw in the river I fish , for the larger bass, are baitfish colored crank baits, spinner baits, and occasionally a chatter bait depending on the water clarity/ structure I am fishing. For lakes a carolina rig magnum worm or lizard can be deadly this time of year. especially when the bass are actively spawning and defending their beds from intruders.
Now remember once the bass get on the beds your tactics should change from targeting feeding bass to triggering aggression strikes form the defensive minded bass. Hope these quick tips help you out over the next two weeks fishing for pre spawning bass. Here is a video from this weekends action using the techniques listed above.
