A rapala shad rap would probably work as well, though I've never used it before. Any popular crankbait should work if the fish are in the right mood. Sometimes the bass love a loud rattlin crankbait, other times they seem to go for a tandem spinnerbait, or maybe it could be a plastic worm day. I guess I just keep on experimenting until I find what works for that particular day (but I usually get stuck on my spinnerbaits longer than I should).
My favorite spots at Beck are:
SE corner just south of the ditch that empties into the lake, the entire E to NE shoreline, and the NW corner. Because fish probably tend to be in warmer water during this time of the year, I like to fish the NW corner in the morning and E side of the lake in the afternoon and evening. Of course, these are just spots where I've caught fish before and are not guaranteed to hold fish in the fuutre (especially since they're also the most over-fished spots at Beck). Guess you just gotta keep on moving if one spot doesn't work out.
(I've only fished the W side of Beck a couple of times before, without any luck. It's a pain to work that side these days with the high water level, but I'm sure there are fish there too.)
