In addition to all else that's been said, watch for areas that are heavy with clay . . .
Clay is a notorious robber of gold and it also likes to trap gold to its surface.
All the best,

I have done a lot of research on the area from the Oro Dam Blvd bridge down stream to the afterbay outlet. The gold they were finding was very fine, most of it was 20 mesh and finer. The largest piece I found records on was 2 dwt. The odd of finding any nuggets are slim to none. I have found some cool relics and old bottles in the tailings. Stay out of the Lake Oroville state recreation area with the detector, they will tag you.
