It's been quite a long time since we fished that pond.  We use
to sneak in through a hole in the fence, on the north side of
the botanical garden.  There were good sized bluegill and LMB
to 10#.  Once every blue moon, the people that ran the garden
would let people fish the pond to thin out the LMB population.
 That's about all the info I can give you.

BTW.  The entrance to the garden is north on Foothill before
the school of theology.  You will see a locked gate w/a no
trespassing sign.
