Thanks to all who have replied, I appreciate all the feed back. I may have made my question a little too general. Having a pond right beside the one I am asking about I believe I have a good handle on water quality issues and the like.(Not in any way implying I know it all) My real fear, so to speak, is what will happen if I have absolutely no shallow areas in the pond. HH, you hit my worry right on when you said it would be detrimental if the water dropped enough to remove spawning areas. That's what I am afraid of when trying to create a perpetual bass/bream population. Would I be better of trying some type of put-and-take fish combo in there. Like HSB and HBG maybe? HH, I apologize if I left out any info, I talk about my pond so much at home I sometimes forget there is anybody I haven't told yet!
