Walleye run - Cumberland River

Is anyone willing to give some general information on approximately when the walleye begin to run up the Cumberland river towards the falls? I fished it about 20 years ago, and have not been back since. About when does it occur? What is the typical water temperature?

Thanks;
WF

50 degrees should get you in the ball park. Hard to time it just right. Heavy rain or a cold snap will really muck things up. I've never been able to time it just right, but I live a couple hours away and work too much! Good luck.
