As long as they've been down, I'd say the sauger will turn around soon. I've always had better luck at catching big sauger in February anyway. I'm hearing reports of big sauger well into March in most years but by then I'm in bass mode.
There was about a 4 day stretch just before that big rain a couple weeks ago that the sauger were on fire according to a few people I've talked to. The guy at Cuba Landing yesterday said the most he'd heard anybody catching in the last few days was 4.
Which is why I crappie fished.
