I am a walleye fisherman from North Dakota and have lived in SW Wyoming for the past 6 years. i can say that I have hit the Sulpher Creek Res. a couple of time for Walleyes, but have not really killed them. I have caught a few smallish ones, but nothing that has got me to head over there instead of the Gorge. Since the Walleyes are there, I hope they do well and prosper. I would rather chase them that the trout and salmon!
