I've caught less than 10 walleye in my life, but I would say that they are the best tasting fish I've ever eaten. We caught them when I was a boy back in the 60s from Okmulgee Creek in central Alabama. I suspect that is the southernmost place they are found, and I'm not sure if it even has any left in it today. There was also a population of them in a couple of creeks near where I live now, about 100 miles NE of there. Those have nearly disappeared now and it's not legal to keep one from those creeks if you did manage to catch it.
A walleye needs cold water to survive, and most of the streams around here get too warm in the summer. I have always wanted to pull my boat north on a walleye trip, but I'm probably too old to attempt it now. I hope you guys enjoy them!
