NAME: Berryessa
CLIMATE: Mild anytime
BEST TIME TO VISIT: Anytime, particularly summer

Local legend has it that the town of Berryessa was evacuated to make room for the new artificial lake that bears its name. Back about ten years ago, during the California drought, it was possible to see a few submerged remains. Submitted by: John Bertolini

It is not a legend; the correct name for the submerged town of "Berryessa" is Monticello. I know, because my father took our family there for a picnic when I was a little girl, over fifty years ago. It was a rainy day in the late fifties so we had our picnic in the car. By this time the houses were all gone and all that was left were trees, bushes, empty sidewalks and some rabbits hopping around. I remember my father telling us that "This will all be under water some day soon." Many years later I visited Lake Berryessa, and recalled the area and saw the sign and the brief history of  the former town of Monticello. It was great validation for my treasured memory.
