I fished Dale earlier this Spring with some guys that are old hat down there including one guy that I would call darn good on that lake. From what they told me and from what they had heard from their buddies and guides that they know down there was the opposite of what you just said. The fish kill knocked the numbers down on mature fish more than the Juveniles. Now this is all water cooler talk but I look at smalljaw.com pretty often and those guys on there are Da Bomb on that lake and I am not seeing NEAR the pics of fatties that I was seeing prior to the fish kill. I do believe as you stated that lakes go in cycles and Dale is in one right now. Yes there are still plenty of fish and some hawgs also but it isn't where it was several years ago. Now the Largehead's have exploded down there, maybe the grass I guess.
Not trying to be argumentative just heard something different. I only get to fish that lake a couple of times maybe a year myself but know quite a few guys that hit it pretty hard. I do think it's in the process of bouncing back though and who knows maybe next year will really start to getting things back to normal.
And to answer your question there were four of us on that trip for 2 and half days and we did not have any over's. We did however have some nice Largemouth...
