Delta Mendota Sub-Basin GSP Webinar Notice

Several Draft Sections of the Single Groundwater Sustainability Plan (GSP) under development for the Delta-Mendota Subbasin are now available for review and comment. This draft single GSP, once adopted, will replace the six GSPs currently being implemented in the Subbasin.

The Delta-Mendota Subbasin Coordination Committee voted to release these draft chapters to provide stakeholders ample opportunity to begin reviewing the document and to submit comments to the Coordination Committee. Final chapters of the GSP will be released at a future date. Please note that these chapters have not yet been adopted by the GSAs in the Delta-Mendota Subbasin.

A webinar will be held on Friday May 10, 2024, at 12:00 pm (noon) to give an overview of the draft sections and information on how to submit comments.

The draft sections and webinar registration information can be found at the link below.

San Joaquin River Predation Study Video

In 2017, the Patterson, Banta-Carbona, and West Stanislaus Irrigation Districts (Districts) embarked on a program to study a pressure on the out-migrating Salmon on the San Joaquin River that is overlooked regarding the preservation of the declining species. This program was developed to evaluate the breadth of impacts that the non-native predatory fish species have on the viability of the native Salmon. Although habitat, water, and food impact the fish, predation is often treated under the window that big fish will always eat little fish.

However, fishing limits and regulations have encouraged the expansion of these non-native populations to encourage a higher quality fishing experience which have pushed out the native populations over time. This study is intended to provide a lens and to focus on the impacts that these non-native populations have on the native fish in the San Joaquin River and the Delta.

The attached video is a snapshot of the efforts that the Districts have undertaken and the work being performed in this study.
