Does Lake Berryessa in California have submergent or emergent coast? -

can anyone tell me if the man-made reservoir Lake Berryessa in California has coastal features more similar to a submergent or emergent coast? Why? Thanks a lot

I would put this under Homework Help or Science Mathematics Earth Sciences Geology because this is for US travel.

Well the water levels change. It s a reservoir, that s what they do. They compensate for rainfall or lack of.
