Wyandotte Creek Groundwater Sustainability Agency

A single Groundwater Sustainability Plan (GSP) is under development for the Wyandotte Creek Subbasin.  The Sustainable Groundwater Management Act (SGMA), passed in the fall of 2014, establishes a new structure for managing groundwater resources in California and requires adoption of a GSP by January 30, 2022.  Development of the Wyandotte Creek GSP is underway and is funded by a Proposition 1 GSP Planning grant. 

The main components and steps for GSP development are described here: https://groundwaterexchange.org/developing-a-groundwater-sustainability-plan/

Basin Setting Chapters

The Basin Setting Project (2018-2020) produced draft chapters for two main sections of the GSP:  the Basin Setting and Monitoring Network.  The draft Basin Setting chapter includes the hydrogeologic conceptual model, groundwater conditions, and water budget information for the subbasin.  Significant portions of the draft Monitoring Network chapter are also available.

Public review drafts of these chapters were released for a 30 day comment period August 10-September 8, 2020.  No public comments were received on the documents during that time.  These chapters will not be considered final until they are combined with the rest of the GSP for review and public comment in mid-2021.

SusTAINABLE MANAGEMENT CRITERIA

The goal of the GSP is to provide a path towards sustainability within the Wyandotte Creek Subbasin.  To achieve this goal, criteria must be established to meet the sustainability objectives.  This section will define the undesirable results, the minimm thresholds which need to be met to meet sustainability goals and the interim measurable objectives.  Draft documents for the Sustainable Management Criteria Section can be found below:

PROJECTS AND MANAGEMENT ACTIONS

Part of the GSP process will be implementing projects and management actions which help move the subbasin towards its goal of sustainability. 

 We want to hear from YOU!  We are looking for ideas about potential projects and management actions (PMAs) that could be evaluated and possibly included in the Wyandotte Creek Groundwater Sustainability Plan.  We have launched an online form to collect your ideas.  Please complete the form and contact us through this link:

PMA Projects Deadline for submittals is 4/30/2021 

Next Steps

Sustainable Management Criteria (SMC) and other portions of the plans are under development.  Preliminary drafts will be discussed by the advisory committee, the GSA Board and public workshops. 

As drafts are available for public comment, they will be posted here.
