I know you were trying to get some info before today, but in
case you're going fishing again soon, here's what I know:

 -Catfish are your best bet- lots of lakes are stocking them
weekly
 -Trout are really deep
 -Nightcrawlers seem to be working very well all around
 -try mackerel, chicken liver, or worms for catfish

 Ok, thats what I know as far as tips go - most of this info
is for lakes in the East Bay.  I spent today at Shadow Cliffs
- no luck for me, but I saw a few nice catfish caught, and
last week someone caught a monster! (I forgot if they told me
it was 22 or 30 lbs...)  I'm not sure about stripers.  What
about Coyote Reservoir?  I've caught some nice catfish there,
and my brother caught a great bass...used mackerel for
castfish near the boat launch, and Senko I believe for the
Bass at the very bottom of the Reservoir near lots of grass. 
Hope this helps...theres a few really cool lakes just south of
SJ, and also across the Bay.  I've been to several, but still
have lots of exploring to do.  Last year at this time I had
great luck over at Chabot on a boat using Mackerel - got 5
catfish in no time!  Good Luck

Oh yeah - about 3+ hours away, I recently went to New Melones
Lake and loved it!!
