production in the South East Management Area since 2019. The South East Management Area includes service areas within IRWD, El Toro Water District and the City of Orange. Together these management areas make up the Basin 8-1 Alternative Plan and the collaborating agencies provide annual reports every year. As required by SGMA, an update to the Basin 8-1 Alternative was submitted in 2022 (see Appendix F ). IRWD’s groundwater production from the Orange County Basin and Sub-Basins is consistent with the approved alternative plan and is in compliance with SGMA.

OCWD Basin Management
OCWD serves as the groundwater manager over the main Basin and sub-basins. Local water retailers are the producers of the groundwater supplies. OCWD adopted its first Groundwater Management Plan in 1989. In July 2015, OCWD updated the Groundwater Management Plan (www.ocwd.com/wp-content/uploads/groundwatermanagementplan2015update_20150624.pdf). This plan has been superseded by the Basin 8-1 Alternative Plan.
