Since the lake has been in flood stage for the last week or so ... and is still 9' over Summer Pool ... and the rain just keeps on coming ... I'm not sure there will be a White Bass Run High, muddy water is not conducive to good spawning conditions.
BUT .... I do not know, first hand, as I have not been down there recently to see for myself. And I haven't fished the White Bass run in many decades. I'm just making an "experienced" guess, considering the current conditions. The lack of any reports is also telling.
