Martis Valley Groundwater Management Plan - Placer County Water ...

Recording of Monitoring Data, Data Management and the CASGEM Requirements
Submit groundwater elevation measurement
data
View and update their CASGEM data, as
needed
With Phase 3 of the CASGEM System, public access to the
Statewide CASGEM data will be available. Users will be able to
download data and view spatial and temporal groundwater
elevation trends in the GIS viewer application.

The Agency has already completed Phase 1 of the CASGEM Program. The next step requires
entry of data for each of the monitoring wells included as part of this Monitoring Program.
Figure 6-1 is taken from the CASGEM On-line System manual. The manual states that “Data
may be entered on a well‐by‐well basis on a system data entry screen, or users can do a batch
upload of information from multiple wells (using a spreadsheet template available for download
within the system).” The latter will likely be the best method for entering the data given that
most of the well information is already captured in an Excel Workbook.
Data entry for groundwater elevations is not fully described but will likely be similar to the well
inventory where a spreadsheet template can be uploaded for all groundwater-elevation data. The
conversion of groundwater-elevation data from a database (including GIS) platform is typically
straight forward with a copy-and-paste step or a small routine that outputs the data in the desired
format.
The inventory of Martis Valley well data will be based on DWR’s CASGEM Monitoring Plan
Summary attached as Appendix B. The set of data fields used for each well will require a
decision on its need based on Appendix B requirements.
