We're strictly "artificial lure" guides and can't speak to the issue of finding shad. I do know that the White Bass population is not only on the way back but we also have some of the Big Un's being caught in with the 10"-12" fish. We took a day off on Memorial Day Monday but on Tuesday we had a three boat Party of ten fishermen and had a 250 limit of nice Sandies in a little over 2 hours. Yesterday, I had a foursome and we managed 90 Keepers before the rain literally ran us off the lake after about an hour and a half. Even better news than the easy limits of Sandies is the fact that the "live bait" guys are telling me the BIG Hybrids are making an appearance in the past three or four days. Quite a few caught on shad off the Flats.
I wouldn't write off RC too quickly as this has been happening for the past three years and every time RC has proved the naysayers wrong. If you're on the lake once every week or so, your chances are a lot lower than the folks out there six days a week. We're catching them in some of the non-traditional spots and have had to look more & longer than the past few years.
Good Luck and Good Catchin'!
