Have I forgot how to fish, or is this a weird year?

My two sons and I are really struggling. We have only caught about a gallon of filets. We switched up trying to catch 'gills this morning, and threw everything we had at them. We tried different depths, different presentations, and different areas. Only caught about a dozen keepers.
our best weekend was two weeks ago, caught real good quality slabs, just not quantity.
Is it the weather, or is it me?

They are all over the place, the weather hasn't helped things. Last weekend caught fish 8' deep. Caught them in less than a foot of water today.

We caught them anywhere from 5-9 feet deep. We just couldn't ever find more than a couple in any one area.
