California Water Code Statutory History

Water Code: California’s history is replete with water issues dating from before it joined the union, however the Water Code was not enacted until 1943. This complicated Code includes municipal- and regional-specific water agencies and districts that also address irrigation, dams, fishways, flood control, drainage and reclamation. Bonds, assessments, and taxes are also part of this Code. Much of California’s water law is comprised of “uncodified acts,” also known and referred to as the “Water Code Appendix.” It is not unusual to find that extraordinary legislative sessions are called by the Governor to address significant water issues of one sort or another.
