I was getting bites from flatheads at night on live white perch near the banks in two the three feet of water a couple of weeks ago, they were apparently cruising the shallows at night looking for a meal. The lake I fish is fairly shallow, most of it 14 to 15 feet deep. this last week we have had a cold snap, with a lot of cloud cover and drizzly rain. I have not been able to get a bite using my usual methods. my question is, should I start fishing deeper? will they still come into the shallows to feed when the lake is rising and the temp is dropping? any tips appreciated.
