I fish the upper end for the most part, but I can tell you that there are a ton of big bass in that lake. If I were looking for a game plan for late april it would absolutely depend on water temp, because if it's really warm you could even be catching post spawn fish on points and secondary points. I spend a ton of those days with nothing but a deep crankbait and a football jig on that lake and Table Rock for that matter.
You could get lucky and find the lake around 6-10 feet high and most of the fish having not spawned yet. If that's the case I would load up on mouse or sexy mouse colored spinnerbaits and beat the heck out of the outsides of the bushes. You'll load the boat and it will be a memorable trip for sure. We've had some epic days from K-Dock to Lead Hill doing that. That's a heck of a long run from where you're staying, but it would be worth trailering a day or two to check out that end of the lake.
I wouldn't be afraid to throw a jerkbait around the outsides of bushes too...
PM me anytime for more info up at that end. I live close to that area and that is where I spend about half of my time off from work.
