I hear these terms used a lot but get confused because they seem interchangeable.  I once heard that structure is what would still be present if a lake were completely drained.  Everything else is cover.  Can people clarify?  Thanks.

Structure refers to changes in the bottom like a hump, shoal, creek channel, drop off, etc....

Cover refers to stuff the bass hide in or around like weeds, wood, docks, rocks, etc.......

Combine structure with cover and usually you have a dandy spot. Example, a hump rising to 10 feet surrounded by 20 feet of water and on this hump is a couple stumps. Bass will most likely position beside the stumps on such a place.

Structure refers to the changes in the lake bottom, such as dropoffs, ledges, islands, humps, points, etc. Cover is objects in the water such as weeds, rocks, wood, docks and the like.
