ML :

I am glad that addition worked \:\) Also thankful that you or trackhoe were not standing on dividing ground when it gave way. That would have been a real swim for life. With all that mixing watch your DO's . You can do the structure and bed work with water in the new part. It will be more work but I do it all the time . ewest

ps: you can still make it ,or part of it, a grow out pond by using a blocking net if you want to . That is what I do . Clear an area drop the net, put in the fish and turn on the feeder.
