As long as the pond suface temps do not stay above 90F for a month at a time WE should live in a pond there. In my expereience WE are more sensitive to lower DO than temps in the high 80" and low 90's for short periods. I think adult YP are more sensitive to higher temps compared to WE. Advantage to YP is they will tolerate low DO whereas WE will not. A pond with WE should be around 15'-18' deep and aerated primarily at night IMO to maximize the DO during hot spells of July-Aug. I would not hesitate to give WE a try and if they don't work you can easily convert the pond to SMB or LMB by just adding these other predators. Adult SMB will tolerate higher temps compared to WE and SMB may toleratre slightly lower DO than WE, but that is just a guess. We need more experiences & lessons of WE in MO and similar latitude ponds.
