B. Description of Proposed Boundary Modification

1. Short Description

   Scientific internal request to subdivide the Kern County Subbasin (5-22.14)
2. Type of basin boundary revision

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

   The proposed modification would adjust a small portion of the boundaries along the eastern edge of the San Joaquin Valley Kern County groundwater basin by establishing a new subbasin. This proposed modification is founded on scientific evidence determined by a recent comprehensive study that demonstrates geological and hydrological barriers impeding groundwater flow and establishing a separate and unique subbasin. The proposed modification would facilitate sustainable groundwater management of the basin because the to-be-formed subbasin has limited connectivity with the remainder of the Kern County Subbasin. Olcese Water District intends on forming a Groundwater Sustainability Agency (GSA) and to coordinate with other public agencies and stakeholders to ensure the proposed subbasin will be properly managed by a GSA. Said modification will promote groundwater sustainability by facilitating the ability to address the unique characteristics and sustainability needs of the proposed subbasin, which are different from those of the Kern County Subbasin as a whole. As a result of the limited connectivity of the proposed subbasin, changes in the conditions of the Kern County Subbasin will not occur, nor will the ability to manage sustainable groundwater in the Kern County Subbasin be negatively impacted.

The boundary then extends to the east along the DWR Bulletin 118 exterior groundwater basin boundary back to Point No. 1.

F. Notice and Consultation

1. List all local agencies and public water systems affected by the basin(s) modification request.

Olcese Water District, County of Kern, City of Bakersfield, Kern Delta Water District, Choctaw Valley Mutual Water Company

2. Explain the methods used to identify interested local agencies and public water systems in the affected basin(s):

Local agencies and public water systems where identified using GIS shapefiles by identifying the boundaries of entities affected by this proposed modification. Additionally, the requesting agency and consulting representative have worked on water and groundwater issues within the area for decades. Thus, they are familiar with the local agencies and local public water systems. Furthermore, representatives from the requesting agency talked with well driller Bakersfield Well and Pump and drove the affected area in an effort to identify any parties that pump groundwater from the proposed subbasin area. The requesting agency also published and posted notice of a public hearing which was held on March 25, 2016. The requesting agency then reached out to all identified affected local agencies and public water systems to explain the modification request, receive input, and coordinate.
