Yes, in ONE year, also, the warmest year on record, fish moved Andy. Guess what, the water in Missouri doesn't get as cold as it does in Minnesota, Ontario or Wisconsin. That is a product of latitude. When the study in the Ozarks is concluded, you can use that study as evidence, but for right now, we cannot judge anything from that study. One year, a sample does not make. The sample size isn't sufficient to draw a single conclusion. If the fish are migrating away, where do fish in the Elk go in the winter? Grand Lake? Oklahoma has NO record of smallmouth bass in Grand Lake, sans ONE monster fish that was caught this year, which is likely a renegade from the Elk or Spring River. One fish does not a population indicate. In the streams in the Ozarks, do they migrate to lakes? Do they migrate downstream only to return to their home pools? Do they migrate to spring holes? Do they migrate to find food or just cover? There are so many questions that must be answered before it can be concluded that they do migrate in the winter. Some do move from their summer haunts to a winter hole, but there is no doubt that fish remain in the same areas in the winter, but in deeper water. Come fish Shoal Creek in the winter and you will see what we mean by this. Spring River is the same way, you can find fish in the same areas that you find them in during the summer. I find it hard to believe that there is such a difference between Shoal Creek and the Huzzah or Courtois as they are about the same size. Perhaps it is that Neoshos don't migrate, but Northerns do, but again, I am not a scientist.
