The efforts to control the Sacramento and San Joaquin Rivers over time, beginning in the 1800's through today, will be studied. How flood control policy developed in California, and how policies have changed over time will be examined. Structural and institutional methods of controlling floods will be analyzed, and the resulting environmental and economic impacts will be discussed.
