i fished badin last with my dad. the bite was really slow. we got 1 blue that was 10-12lbs and 1 channel and a bunch of white cats. i noticed that i couldnt mark any fish on my depth finders. there was so much static on the screen that it was blacking out down to 28 ft. had to turn the sens. way down to try and find fish but that didnt help much at all. i have seen this several times at badin in the dark but when i go back in the daytime its not there. i dont know if this coming from thermocline building up or boat traffic on the lake. its not bait. my dad said it may be plankton or something that shows up at night. anyway if any body knows i would like to hear about it.
