DWR is the State agency responsible for oversight of the GSAs and GSPs (or Alternative Plas). DWR has a list of regulations, objectives and actions formulated to assist local agencies and GSAs with the preparation and implementation of GSPs and Alternative Plans. Under law, all regulations adopted by DWR only become effective upon approval by the California Water Commission. The State Water Resources Control Board (SWRCB) acts as the enforcement agency that reviews water use data and has the authority to directly manage basins as a result of failure by locals to comply with SGMA requirements (i.e. create a GSA, adopt and implement a GSP or Alternative Plan).
