B. Description of Proposed Boundary Modification

  1. Jurisdictional Internal Modification to accommodate bifurcated entities.
    • Jurisdiction Internal
  2. Jurisdictional internal modifications are proposed to bring areas that straddle the Delta-Mendota basin and an adjacent basin to be fully within the Delta-Mendota basin. Areas being removed from the Delta-Mendota basin and into the Westside Basin are being coordinated by the Westlands Water District. Areas being removed from the Madera Basin and added to the Delta-Mendota basin are being coordinated by the Aliso Water District. Operating within one Basin will allow for simpler governance and an increased ability to sustainably manage groundwater.

G. General Existing Groundwater Management

All requests for jurisdictional modification pursuant to Section 342.4 MUST include responses to the following questions.
The San Luis & Delta-Mendota Water Authority (SLDMWA) acts as an umbrella organization serving many of the Districts within the Delta-Mendota sub-basin with water and groundwater management. SLDMWA has organized agencies and prepared regional groundwater management plans for both the Northern and Southern portions of the Delta-Mendota sub-basin, and acts as the CASGEM monitoring entity. SLDMWA also serves as the IRWMG for the Westside-San Joaquin Region. The above efforts demonstrate a willingness and ability to collaborate, and a wealth of regional data collected, all of which will be required to successfully manage groundwater for sustainability.
The intent of the SLDMWA request is to assist areas that overly multiple basins to reside in a single basin. The adjacent agencies and basins have been receptive to the proposed changes to the Delta-Mendota basin boundary. They recognize the difficulty these agencies would face managing for two different GSPs, and that this ease GSA formation and GSP implementation in their basins as well.
As noted in the Northern GWMP, groundwater levels appeared to be generally hydrologically balance over the period of 1993 to 2008, with some areas of decline and some areas of surplus. The Southern GWMP indicates that this area is subject to shallow groundwater, and that groundwater levels in much of the southern area are managed by the collection and removal of shallow groundwater which is accomplished through the installation of subsurface drainage systems. The central area of the Delta-Mendota sub-basin has been discussed in the San Joaquin River Exchange Contractors Water Authority's GWMP. Groundwater in this area is used to supplement surface water supplies when necessary. This occurs during dry years, and when the surface water extraction peak rate limitations in-place in the water supply contract. The southern modifications in the area of the Traction Ranch have been previously discussed in the Lower Kings Basin GWMP. This area to be included in the Delta-Mendota Basin is represented by Area ""A"" of this GWMP. Area ""A"" is quite large in relation to the area of interest. Area ""A"" is highly reliant on groundwater and has experienced downward trends in groundwater levels. however the Traction ranch area is influenced by the San Joaquin River and Mendota Pool.
The only State program that could be affected is CASGEM. It would make sense that SLDMWA be the monitoring entity for the entire Delta-Mendota Sub-basin after the basin boundary modification takes effect. This boundary modification is a positive impact to the groundwater management plan in the northern basin, as it will bring the districts it represents fully within the Delta-Mendota basin.

H. Local Support

All requests for boundary modification must include the following:
The attached letter (with maps) was sent to affected agencies to inform and request support. Also, once the proposed basin boundary modification request is deemed complete by the DWR, then the attached letter will be sent to the affected agencies noted above.

None yet. Awaiting opposition.

I. Hydrogeologic Conceptual Model

Requests for boundary modification, must include a document or text to a clearly defined hydrogeologic conceptual model demonstrating each of the following:
It is requested that the Hydrogeologic Conceptual Model be waived for this internal boundary modification. This modification does not introduce any new hydrologic or geologic features that would impact sustainable groundwater management in any of the affected basins.

L. Technical Studies for All Jurisdictional Modifications

Requests for a jurisdictional boundary must attach or provide a URL or upload a file for the following:
SLDWMA has taken the lead to organize the Delta-Mendota Sub-basin in response to SGMA. Meetings are being held in different regions to facilitate the formation of GSAs. SLDMWA is also reviewing and providing recommendations on MOUs and JPAs for the organization of the Delta-Mendota Sub-basin agencies.
