They are right on the money, look for new run off thats flowing into the lake and also fish any recently flooded areas.
Big spinners with colorado blades are great so are black, june bug, or pumkin seed chartruse jigs and make sure your trailer has plenty of vibration. You should also look into adding some rattles to them.
Chartrues is a big winner right now and beleive it or not the fish will suck up into the shallow cover to hunt even though it may be cold. Look for areas without current if that is a problem.
If you normally use smaller baits go big because often all these fish will see will be the silloette. Keep in mind that even though the fish are shallow their strike zones are still small. So don't be afraid to hit them on the head with that bait. Wide wobbles on those crank baits is a plus right now. The key is that the fishhave to see it or hear it to eat it.
Good luck,
Peter
