black crappie tend to hang to the concrete in the summer months under bridges early in the day . not many folks understand the eating habits real well on the 2 different species . there is a big plankton type thing about 1/4 inch long that likes to hang around under bridges early in the day .
the white crappie love to chase shad herds and often wait in ambush and or rest during the day in piles and along timber edges . knowing more about the crappie will put you on them more frequently .
that said bridges are just a spot to get when its hot and you need shade most of the time in the summer
deep water timber on Palestine would be where I would look myself this time of year
