Taylor,
I live South of San Jose so if you show me where it is, I won't be hitting your spot more than once or twice a year if that. I need to give the Trophy lakes near me a short rest. They seem to know me on sight and either run and hide or thumb their noses at me. The last 3 mornings that I've tried stopping by the lake before work, I've seen a 10+ sunning herself at a specific spot. She won't touch anything. Then again I haven't hooked anything much over 5# since the end of Sept.
As for why you aren't getting them at your spot, have you tried scent? I like Pro-Cure Bait-Butter in Rainbow Trout, Shad, Crawfish and Smelly Jelly's CrawDaddy and Bass Feast. I also have a tube of Mega-Strike but it doesn't seem to help me at all, rather I seem to get fewer fish with it, maybe I got a bad batch.
One more thing you might try (especially when they're more aggressive), is to get a custom deep diving 4-Eyes from Fish JC. The 1 I had would barely tick bottom at 20' on a Long cast. With the 2 trebles you might get a double.
Tight lines,
Wade
