B. Description of Proposed Boundary Modification

1. Short Description

   The first modification is jurisdictional and adjusts the southern boundary of the Madera Subbasin GSA to a more up-to-date representation of the Madera County boundary. The second modification is scientific and removes the exclusion of Madera Lake.
2. Type of basin boundary revision

   • Scientific Internal
   • Jurisdiction Internal
3. Provide a narrative overview of the boundary modification request and how the resulting modification would affect likelihood of sustainable management.

   Madera County would like to request that DWR modify the definition of the Madera and the Kings subbasins such that the southern boundary of the Madera subbasin follows a corrected representation of the Madera County boundary, and the Kings subbasin's northern boundary becomes the same line. When viewing the GSAs current delineation along the southern boundary, several inconsistencies are created that need to be resolved. The current mapping of the basin's southern boundary follows the San Joaquin River, as defined by Bulletin 118 and represented in various DWR on-line viewing tools, and uses the Madera/Fresno county line as depicted in the file DWR accessed from the California Department of Forestry and Fire Protection. The result are several areas where the North Kings subbasin and the Madera subbasin either (1) overlap, (2) leave parcels outside of either subbasin, or (3) unintentionally extend into the other county's jurisdiction. These inconsistencies can result in: One or more assessed parcels (as recognized in the county assessor's books for Madera and Fresno counties) may be within the Madera GSA, or within the North Kings GSA contrary to the county designation recognized by each county's assessor for these same parcels. Groundwater modeling inappropriately distributing the benefits of the San Joaquin River's recharge and any use of recharge facilities along the River's floodplain (if such are designated) among the two subbasins. A few assessed parcels not included in either the Madera County GSA or the North Kings GSA, potentially leaving them unrepresented in GSP development and implementation. Additionally, on behalf of the entire subbasin, Madera County is requesting that DWR remove the exclusion of Madera Lake.

6. Any information, if necessary, to enable DWR to satisfy the requirements of a responsible agency pursuant to the California Environmental Quality Act.

CEQA compliance is not required for these modifications as they are (1) refining DWR's representation of the Madera/Fresno County line, and (2) correcting DWR's exclusion of Madera Lake to include it within the subbasin.

E. General Information

1. Describe the lateral boundaries of the alluvial aquifer or aquifers that form the groundwater basin and the definable bottom of the basin. The description must be in terms that are clear, definite, and sufficiently detailed to allow an authoritative map of the proposed basin boundaries to be plotted using the given description.

New information: Section 3.1.2 and Figure 3-5 in the attached memo describe lateral boundaries and bottom of the basin (a) For the Madera/Fresno County line, the lateral boundary along the southern boundary of the Madera Subbasin will use the representation provided in the GIS shapefile submitted under D(4) and D(5). There is no change to other subbasin attributes. (b) For Madera Lake, the current exclusion follows the designation in DWR's Bulletin 118 which uses a segment description stating: starts at point (17) and generally follows the shoreline of Lake Madera then returns to point (17) that removes the Lake from the middle of the Subbasin. This segment would be removed, returning the Lake to the Subbasin, consistent with its current use by Madera Irrigation District for water management and percolation.

5. Attach a copy of all comments regarding the proposed boundary modification received by the requesting agency and a summary of any responses made by the requesting agency.

No comments were received.

G. General Existing Groundwater Management

1. Explain how sustainable groundwater management exists or could likely be achieved in the basin:

Sustainable groundwater management could likely be achieved within the basin through a combination of supply augmentation, including harnessing flood flows for groundwater recharge as well as other projects, and potentially demand management.

2. Explain how the proposed boundary modification would affect the ability of adjacent groundwater basins to sustainably manage groundwater in those groundwater basins.

The jurisdictional boundary modification will allow groundwater basins to sustainably manage groundwater by eliminating inconsistencies in boundaries, appropriately distributing the benefits of the San Joaquin River?s recharge in modeling; and representing all parcels in GSP development and implementation. Including Madera Lake within the Madera Subbasin, a scientific boundary modification, provides an opportunity for seepage/recharge at the lake itself.

3. Provide a historical summary of the sustainable management of groundwater levels in the proposed basin(s) or subbasin(s).

Please see Section 3.1.2 regarding management of groundwater levels in the Madera subbasin over time and Appendix C.

4. Discuss potential impacts to state programs resulting from the proposed boundary modification, including, but not limited to, the California Statewide Groundwater Elevation Monitoring (CASGEM), Groundwater Management Plans developed pursuant to AB 3030, Groundwater Sustainability Plans developed pursuant to the Sustainable Groundwater Management Act, any applicable state or regional board plans, and other water management and land use programs.

These modifications are extremely minor and would not impact state programs.

2. Provide a list of all affected agencies and affected systems that submitted comments and/or documents in support or opposition to the proposed boundary. The agency submitting their support or opposition for a boundary modification must provide a copy of a resolution formally adopted by the decision-making body of the affected agency or system or a letter signed by an executive officer or other official with appropriate delegated authority who represents the agency or system. Attach copies of the resolution and/or signed letter detailing the support or opposition submitted.

North Kings submitted a letter of support (minus one parcel, which needs to be corrected by Cal Fire). Madera Irrigation District submitted a letter of support. Triangle T Water District submitted a letter of support for this modification and one in the Chowchilla Subbasin.

I. Hydrogeologic Conceptual Model

1. Principal aquifer units within requested basin.
2. Lateral boundaries of the proposed basin, including:
   1. Geologic features that significantly impede or impact groundwater flow.
   2. Aquifer characteristics that significantly impede or impact groundwater flow.
   3. Significant geologic and hydrologic features and conditions of the principle aquifer units, as appropriate, including information regarding the confined or unconfined nature of the aquifer, facies changes, truncation of units, the presence of faults or folds that impede groundwater flow, or other groundwater flow restricting features.
   4. Key surface water bodies, groundwater divides and significant recharge sources.
3. Recharge and discharge areas within the basin.
4. Definable bottom of the basin or subbasin.

The department may waive this requirement for an internal boundary modification if the requesting agency is able to demonstrate that the proposed boundary modification is unlikely to affect sustainable groundwater management.

Please see the entire Section 3 of the attached TM, including several Figures (3-1 to 3-15) and Table 3-1, plus appendices B through F.
