B. Description of Proposed Boundary Modification

1. Short Description

   Jurisdictional internal modifications bring New Stone WD fully witihin the Madera Sub-basin
2. Type of basin boundary revision

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

   New Stone Water District's boundaries overlie two basins: the Madera and the Chowchilla sub-basins. New Stone WD proposes to modify the existing basin boundary, moving he dividing line northerly to position the New Stone WD wholly within the Madera sub-basin. Operating within one basin will allow for simpler governance and increased ability to sustainably manage groundwater.

G. General Existing Groundwater Management

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

New Stone WD currently relies on pumped groundwater as its main supply. This groundwater is principally recharged by the Chowchilla Bypass. The District is currently split between the Chowchilla and the Madera Sub-basins. Managing the District in two different basins, and complying with two different GSPs is unnecessary. New Stone WD's water supply is more greatly influenced by the Madera Sub-basin. Many of the actions mentioned in the Madera GWMP to rectify undesirable results, are similar to methods that could be used by New Stone WD, given their similar water supply and geology.

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

The adjacent basins have been receptive to the groundwater basin boundary modifications. They recognize the difficulty New Stone WD would face managing for two different GSPs, and that this will ease GSA formation and GSP implementation in their basins as well. Since New Stone WD is mostly reliant on groundwater, the Chowchilla Sub-basin will likely have an increased ability to manage its water supplies in a sustainable manner.

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

While largely reliant on groundwater, New Stone WD has made an effort to take surface water from the Chowchilla Bypass when available, and to improve their irrigation efficiency. These practices along with the influence of the San Joaquin River restoration, has improved groundwater reliability in the area. A Madera Regional Groundwater Management Plan also exist for Madera County. it consisted of many agencies in the Madera and Chowchilla Sub-basin working together to identify county wide issues, such as long-term overdraft. Not only does this demonstrate a history of management of groundwater, but also an ability for the basin to work together towards a common goal. These GWMP identified many corrective actions that could be used to rectify problems if they are determined to be significant and unreasonable during the development and implementation of the GSP.

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.

The only State program that is likely to be impacted is CASGEM. Fortunately, the Madera-Chowchilla CASGEM group covers both the Madera and Chowchilla sub-basins. It may have an affect on how data is managed and submitted, but it will be covered by the same entity.

H. Local Support

1. Provide any evidence that sufficient information was provided to affected agencies and systems regarding the proposed boundary modification.

The attached letter has been sent to affected agencies informing them of the proposed basin boundary modification, and requesting their support. Also, Once the proposed basin boundary modification request is deemed complete by the DWR, then the attached notification letter will be sent to the affected agencies as well.

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.

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.

it is requested that the Hydrogeologic Conceptual Model requirement be waived for this internal boundary modification. This modification does not include new hydrogeological features that would impact sustainable groundwater management in either the Madera or Chowchilla sub-basins.

L. Technical Studies for All Jurisdictional Modifications

2. A statement of the existing and planned coordination of sustainable groundwater management activities and responsibilities where required.
