Wind is gonna make a big difference for you, Edwin. Hang in there, buddy. I feel your pain. I've thrown a pile of money at derbies the past two weekends and come away "checkless." Don't let Babler woo you with his siren song about that dastardly float-n-fly. Resist, my brother. Get thee behind me, evil one.
Seriously, they're gonna turn on bigtime any day now. I had a good bite going up the Kings week before last in 50-53 degree water. Very few big fish and hard to even put together a sack of keepers but by gosh it was fun. They slowed down a lot last week when the water temp dropped a bit, but I'd bet they're getting back on their feed by now. Viola marina to near the Hwy 86 bridge. Shallow crank baits (Bandit 200s or even 100s) around big rocks or wood. Spinner baits were starting to work, too. Go up there and enjoy. Sounds like you need some bites, big or small.
