Tech Memo PurposeDescribe the historical data sets and established monitoring networks in the basins and how data gaps could be filled in the future. Draft Tech Memo components include:
• Historical available groundwater level and water quality dataset distribution
• Established monitoring sites distribution• Trends analysis of groundwater level and groundwater
quality constituents• Potential temporal and spatial data gaps• Recommendations

Kinds of Monitoring Networks
• Groundwater Levels
• Groundwater Production
• Groundwater Quality
• Surface Water Quality
• Streamflow Gauging
• Precipitation
• Evaporation
• Subsidence
• Ecological

Tech Memo does NOT describe the following networks...
• Subsidence
• Ecological
Where are these elements defined?Separate Tech Memos

SGMA requires aquifer-specific evaluation and identification of “Primary Aquifers”.
Groundwater Level & Quality
What Information is needed?• Well Construction (DWR WCRs)• Hydrostratigraphy Mapping (UWCD BCM)
