best bet is the pavillion which is accessed through the back gate.
with the water down, the weeds between to old edge and the waterline can be crazy.
there are a couple of triathletes that keep a path open.
i haven't seen anyone camping, so not sure about the campsite access to the water.
that would be up and over from cush lot, down to the campground road. through one of the campsites.
i see people that go into the scuba lot, and let the dogs run along the water there.
might be $5 to get in weekdays.
