Overview • Analysis Approach • GSP Sections Overview • Umbrella/Chapter GSP Outline Comparison Overview • GSP Development Process • Basin Settings • Next Steps
Analysis Approach • Approved regulations • Excel version • Diagram Development • Detailed Outlines • Chapter and Umbrella Outlines
GSP Sections • Introduction • Basin Setting • Sustainability Goal • Monitoring Networks • Minimum Thresholds, Measurable Objectives, and Interim Milestones • Water Supply Accounting • Projects, Management Actions, Adaptive Management • GSP Reporting
GSP Section: I ntroduction • GSP implementation costs • GSP funding plan • Description of plan area – 8 maps – Document surface conditions • General plans summary • ID and describe GSP effects on parties in basin • Outreach/stakeholder communication compilation
GSP Section: Basin Setting • Data management system • Hydrogeologic conceptual model – Principal aquifers and aquitards • Parameters and boundaries/extents – 6 more maps, cross sections, basin boundaries • Groundwater conditions – Contour maps – Change in storage – Hydrographs – Seawater intrusion maps/xsection – More maps (WQ, subsidence, SW systems, ecosystems) – Timing and quantity of stream depletions
GSP Section: Basin Setting • Water budget – 20 years historical • ET data (satellite) • Pumping data (estimated) • SW components – Sustainable yield – Change in storage – Numerical model • Data projections (SW supply, land use, etc) • Forecast climate change? • Calibration • SW/GW interaction • 50 years projected
GSP Section: Basin Setting • Existing monitoring – Programs – Data collection – Suitability for SGMA – Levels, WQ, subsidence – Into DMS • Management areas – Begin to ID
GSP Section: Undesirable Results • Undesirable result narrative – Programmatic language – Stakeholder outreach • Agencies • Public • Landowners – Stakeholder education – Evaluation of occurrence – Evaluation of affect on beneficial uses
GSP Section: Monitoring Networks • Develop representative monitoring – Justification • Monitor for each aquifer in basin: – Spatial density, frequency, maps, protocols • Data gaps and plan to fill • Summaries • Data management
GSP Section: Thresholds Example Diagram
GSP Section: Thresholds • Representative monitoring (again) • Methodology for thresholds • Measurable objectives, minimum thresholds, and interim milestones that cover • Graphs with thresholds for each key monitoring point • Maps and tables
GSP Section: Water Supply Accounting • Water accounting framework – Development – Updates – Accounting • By agency and/or by landowner • Allocation strategy – How the sustainable yield ‘pie’ is divvied up
GSP Chapter: Projects, Management Actions, and Adaptive Management
GSP Section: Projects, Management Actions and Adaptive Management • Management program – Document development of projects – Analyze affect of projects/MAs/AMAs • Projects • Management actions • Adaptive management – Quantifiable trigger points
GSP Section: Projects, Management Actions and Adaptive Management • Document for each project, MA, or AMA – Outreach – Permitting – Benefits explanation – Source of water if used – Legal authority – Costs and funding – Addressing uncertainty – CEQA considerations
GSP Section: Reporting • ID annual report content • ID 5 year evaluation content • Develop plan to prepare reports • Data management plan • Monitoring network updates • GW model updates?

GSP Development Process Basin-Wide Need to Then know first
Basin Settings
Basin Settings • Hydrogeologic Conceptual Model – Describes physical framework that groundwater moves within • Geologic Formations • Barriers to Flow • Aquifer parameters
Basin Settings • Groundwater Conditions – Describes/shows how water moves within the framework • GW elevation, • GW flow directions, • GW gradients, • GW changes over time • GWQ/Salinity • Connection to SW
Basin Settings • Water Budget – Describes/shows the amounts of water • SW • GW • Precipitation • Extraction • Uses • ET • Historic/Current/Future
Basin Settings Basin Settings Hydrogeologic Groundwater Conceptual Water Budget Conditions Model Historic and Numeric Current Water Model Budget Forecast SW/GW Underflows Water Budget Interaction
Basin Settings Process • Collect best data • Build database of data (DMS) Used to populate • Hydrogeologic Conceptual Model and calibrate • GW Data/trends (Conditions) model • Create generalized Water Budget (20 years historic/current) • Add Data to C2VSIM GW Model • Recalibrate? (unclear) then use to – Underflows – SW/GW Interaction – Forecast Water Budget • Use model outputs to complete Water Budget
Next Steps • Late April / Early May workshops for other GSP sections • Comments
