Twenty years before the adoption of SGMA, Coachella Valley Water District began development of the 2002 Coachella Valley Water Management Plan to address groundwater sustainability in the Subbasin. That plan was updated in 2010 as the 2010 Coachella Valley Water Management Plan Update. In 2014 and 2016, Coachella Valley Water Management Plan Status Reports were prepared to review the planning assumptions and implementation status. Annual reports describing changes in water supply and demand and updates to management actions, as required under Section 356.2 of the GSP Emergency Regulations, are submitted to DWR. The Indio Subbasin Annual Report for Water Year 2018-2019, the third annual report for the Indio Subbasin, is expected to be submitted in March 2020.
