Frank, personally I like the location of your main feeder on the dam. I would consider a "yard-arm" hanging feeder on the dock.
George,
The CNBG are feeding so well I almost hate to move the feeder. My original plan was to build a simple walkway/pier adjacent to the boat ramp with a feeder on the end of it, which is essentially in the far corner of the dam. Then move the existing feeder to the dock which should give decent coverage to both sides of the pond. I really want a feeder on the dock to take advantage of watching the fish feed up close. It will also keep me from negotiating that slope on the dam to fill the feeder.
