I wish that August had the highest temperatures. The past several years this hasn't been the case.

True, but I would argue that fish suffer more stress around low oxygen levels than they do when spawning. In fact fish are at thier strongest during the spawning period, nature would intend it that way. How often do you hear of a hard fighting fish full of spawn. They feed well before spawning so that they are strong and recover quite quickly afterwards. However during low oxygen levels they suffer a lot of stress. These levels in the main come either in July or August and start at around 70f. I don't have the science to back that but, I bet it is not far off. For these reason I would argue a CS based around high temperatures oxygen levels would be a better one than based around spawning. Picking an exact period covering when this is most like to happen would have to be July/August but, I favor August as it is still just about the month when these conditions happen but, I agree that has been changing over the last few years.
