Floods of Northern California


With Rollie Lamberson, Jerry Rohde & Nancy Dean

Examine the history of epic North Coast floods and the weather patterns that spawned them. Rainfall records in December 1955, produced flooding, 74 deaths and $200 million damages. A horrible prelude to the storm of December 1964, which produced record high flows on every river in the region. Whole towns disappeared, and the North Coast was isolated for weeks.
