Bob informed me several weeks back that bluegill prefer spawning in 6-18" 0f water. However, Mike Otto and others say that you should not have any water less than 3' deep in your pond to keep weed growth down. I'm building a new pond and it's time to set the depth/slope of the banks. I want to create good bluegill spawning areas, but I don't want a weed problem. So what do I do?
