Discussion and Possible Direction Regarding the Hydrogeological Conceptual Model (HCM) Under Development for the Groundwater Sustainability Plan Chapter
Presenter/s: Chris Petersen, GEI Consultants, Laura Foglia, Larry Walker and Associates and Amir Mani, Larry Walker and Associates
Introduction: This Hydrogeologic Conceptual Model (HCM) has been developed by GEI Consultants (GEI) for the Ukiah Valley Basin Groundwater Sustainability Agency (UVBGSA) for inclusion
in the Groundwater Sustainability Plan (GSP) under the requirements of the Sustainable Groundwater Management Act (SGMA). The purpose of this HCM is to meet the regulatory requirements
mandated by SGMA along with establishing a framework hydrogeologic model with which to guide development of the GSP and management of the basin, including future modeling efforts and
monitoring programs. GEI provided the draft HCM and a PowerPoint reviewing the HCM structure, SGMA requirements, signification sections and changes.
Discussion:
Request for GEI to provide a map with lateral extend for Aquifer 1
Is the spring properly accounted for in the surface water characterization? Particularly along the western hills of the Ukiah Valley where tributaries flow all year. Suggestion from
TAC to possibly add a field investigation component to the Proposition 68 application to help further refine the surface water characterization.
Sonoma Water has data it could possible share for water quality along the mainstream of the Russian River from Sonoma Water’s monitoring program following the 2017 fires.
Suggestion from the TAC to also review the water quality reports for the Ukiah Valley water districts for additional water quality data.
Committee Action: Feedback to staff regarding surface water characterization and water quality data.
Update and Discussion Regarding the Data Management System
Presenter/s: Chris Petersen, GEI Consultants
Introduction: GEI Consultants provided an over of the Data Management System (DMS) features including viewing data, important templates, importing data and overview of data currently

the DMS.
Committee Action: None.
Update and Discussion Regarding the Preliminary Water Budget
Presenter/s: Laura Foglia, Larry Walker and Associates and Amir Mani, Larry Walker and Associates
Introduction: LWA presented to the TAC on the preliminary water budget including the root zone water budget, hydrological model, groundwater model and integration.
Discussion:
Feedback to work with County to include cannabis in the Agricultural projected water use. County can provide location, size and type of cannabis cultivation.
Feedback from the TAC that additional details are need on the use of heat protection (temperature data, use methodology and record of when and where it happens).
Sonoma Water willing to share information on what is being used for their frost modeling.
Suggestion to include the dew point in frost modeling.
TAC request an update on the model at next meeting.

Presenter/s: Sarah Dukett, Mendocino County Water Agency, Laura Foglia, Larry Walker and Associates and Amir Mani, Larry Walker and Associates
Introduction: The Mendocino County Water Agency provided a status update on the Technical Support Services (TSS) application. Due to some well locations falling through, the proposed
October drilling timeline has been changed by DWR to spring 2020 to accommodate finding new well locations for central and northern Ukiah Valley. LWA provided a written overview of
the status of each transect under development. The Mendocino County Water Agency and LWA request suggestions from TAC members for central Ukiah Valley alternative sites. The Mendocino
County Water Agency will be working with the Ukiah School Board regarding securing well locations at both Redwood Valley schools.
Discussion:
Recommendation for a 6 month lead time to work with the Mendocino County Resource Conservation District and the Mendocino County Water Agency to incorporate new well sites into the CASGEM
network.
Question from TAC regarding data privacy for private well owners. Only owners and technical staff have access to the continuous data collected, protection measures will be in place so
specific locations are not identifiable and data will only be published monthly or quarterly.
Committee Action: Recommendation to staff regarding TSS network inclusion in the CASGEM program.
