To me, step one is why is it ten ft low? I had to look up autumn olive. Sounds like nasty stuff. If you kill it will it compromise the integrity of the dam? Has it already done so? Or, could it be why the pond is low?

Not sure you can fish your way out of a crappie infestation. I’ve never had to try.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP
