State Water - Board Cannabis Cultivation Programs

Cannabis Cultivation

Welcome to the State Water Resources Control Board's (State Water Board) cannabis cultivation regulatory programs webpage. The State Water Board is developing and implementing new regulatory programs to address potential water quality and quantity issues related to cannabis cultivation and to meet the directives of Senate Bill (SB) 837 (Statutes 2016, Chapter 32, Committee on Budget and Fiscal Review) and the Medical Cannabis Regulation and Safety Act.

The Water Boards (State Water Board and Regional Water Boards) responsibilities under the Medical Cannabis Regulation and Safety Act and SB 837 encompass the State Water Board's Division of Water Quality; Division of Water Rights; Office of Enforcement; and Regional Water Quality Control Boards (Regional Water Boards). The State Water Board is conducting outreach and participating in stakeholder meetings while developing the Cannabis Cultivation programs.

The Water Boards' cannabis cultivation programs focus on water quality protection requirements associated with the cultivation of cannabis on private lands. Cannabis cultivation on public lands is illegal and may be subject to criminal prosecution. The State and Regional Water Boards' water quality programs do not authorize, endorse, sanction, permit or approve the cultivation, use, sale or other activities associated with cannabis.
