First off bank fishing is tough, ESPECIALLY in socal... Most of the public lakes are highly pressured so keep that in mind. Mitch also posted a fairly accurate picture of bank fishing.
What am I doing wrong? Or are these numbers typical of fishing from a (rocky) point (into rocky terrain)? I'll catch fish at one part of the point, then after hours of nothing, move to another part of the same point, and hopefully get a second.
Happens to me all the time at my favorite lake especially big ones. But you seem to be on the right track... except don't stick around to an are for "hours of nothing". Give it maybe 20minutes if you are fishing slow and move to a new spot... you gotta find the fish they aint gonna find you
Are the fish spooked after I catch the first? Though on my best (four-fish) day, I caught three in a span of 45 minutes from another point at the same lake, in 102 degree weather, with boats/seadoos galore, creating lots of waves.
From my experience, no they don't get spooked unless they see you up close. Boats creating lots of waves from where? near shore? Usually they are speeding through at the deeper end of the lake (unless the lake is shallow overall).
Is my problem that I'm pretty much only dropshotting?
No man lol. Drop shot is a very good technique and works year round. But you gotta understand it doesn't mean all bass will take it... other techniques are maybe better then drop shot given the time of year, conditions of lake, presentation, etc. Be confident in what you are using... and just build up on experience... time on the water..
