General information regarding potential basin boundary modification process is posted or will be posted.

• http://www.ohwd.org

• • The Omochumne-Hartnell Water District overlies both the Sacramento Valley South American Subbasin (5-21.65) and the San Joaquin Valley Cosumnes Subbasin (5-22.16), and participates in groundwater management efforts in both basins. The existing groundwater basin boundary along the Cosumnes River splits several entities into both the South American and Cosumnes Subbasins. However, OHWD's land uses are more consistently aligned with those of the Cosumnes Subbasin. • The proposed modification would shift the boundary of the Cosumnes Subbasin north along the OHWD boundary line, and would be submitted jointly with the Sloughhouse Resource Conservation District. The new northern boundary of the Cosumnes Subbasin would follow the OHWD and SRCD northern boundaries which coincide with Grant Line Road, and then further follow the Cosumnes River watershed boundary to the northeast, which closely follows SRCDs jurisdictional line. Historically, the area covered by this boundary modification request has been analyzed in groundwater management plans (GMPs) promulgated by both Sacramento Central Groundwater Authority (SCGA) and Southeast Sacramento County Agricultural Water Authority. However, the land use and hydrology in the proposed modification area are more consistent with the Cosumnes Subbasin than the South American Subbasin. • OHWD has engaged in trilateral meetings with SRCD and SCGA to develop a plan forward for this area of the basin, and looks forward to continued collaboration between GSAs in the region. The proposed modification would promote the likelihood of sustainable management and the establishment of a groundwater sustainability plan in the Cosumnes Subbasin by providing leadership to the Subbasin, focused local control within public agencies' jurisdiction, decreasing the isolation of regions with limited economic and staff resources, and creating better integration between surface water and groundwater boundaries.
