Structure is what you look for when studying a topographical map. The trees, stumps, laydowns, brush piles, and such like that are in our reservoirs are cover. Fish will certainly relate to these objects when they are holding on a certain piece of structure, but, the fish are there because of the structure, not because of the cover. This Lesson was really driven home a few years ago when a number of brush piles were placed in my home lake. Of the ten or so brush piles dropped in various places around the lake, fewer than half of the were really good producers.
Fish utilize cover when the cover is where the fish wants to be.
On a lake like Caddo or Bisteneau the predominant cover is living green cypress trees. A first time visitor to choke Canyon or Lake Fork is overwhelmed by the amount of standing timber. It all looks the same. The whole objective changes complexion when you apply basic structure fishing techniques. The fish are not evenly dispersed throughout all the cover on the lake.
