HighnDry: "I thought that this was interesting point, but I'm not really clear as to why Lake Erie would have such a drastic increase in walleye versus inland waters (proportionately speaking).
"In Lake Erie, where 2017’s landmark natural population spike is expected to explode into some 5 million ‘eyes this year, all of the ingredients including water chemistry, temperature and habit exist in abundance in the lake’s great western nursery waters. But on inland lakes in Pennsylvania and Ohio, natural reproduction is too inconsistent to reliably produce a viable walleye fishery. "
Maybe it's the regulations that allow for no-size limits and year-round harvesting?

The vast majority of lakes do not support walleye reproduction no matter what the regulations are. Sad but true.
