Shane, I have fished Folsom many times(used to live in roseville). Fish the rip rap on either side of the dam with a small jighead and single tail yamamoto grub (grn or brown). I was there for a week last June, caught no less than 30 per day(spotted bass,biggest 3#) -Jack

Fished it a number of times about 12yrs ago when I lived in the sacto area.  I always looked for the long points sticking out into the main lake in the late spring thru summer months.  In early spring thru the spawn look for the protected coves and fish secondary points in them.  Always did well with tube baits at this lake and split shot hand pour 4" to 5" worms in blue / silver colors.
