Statutes and Regulations

The Statutes and adopted Regulations enacted for the State supervision of all jurisdictional dams are available to review here.




  • On June 27, 2017, SB 92 required emergency action plans for all dams that do not have a low downstream hazard potential, as determined by the Department. SB 854 amended California Water Code section 6161 on June 27, 2018, to clarify requirements for dams with an EAP as of March 1, 2017.
    • If the EAP did not have inundation maps for all critical appurtenant structures at your dam, you must submit a schedule to DSOD by August 25, 2018, to complete the maps. Notice to Owners of Dams with EAPs as of March 1, 2017.
    • If you did not have an EAP as of March 1, 2017, this change does not affect you.
