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

• The Sloughhouse Resource Conservation District (SRCD) jurisdiction is currently in both the Sacramento Valley South American Subbasin (5-21.65) and the San Joaquin Valley Cosumnes Subbasin (5-22.16). The existing groundwater basin boundary along the Cosumnes River splits several entities into both the South American and Cosumnes Subbasins. The Omnachemne Hartell Water District (OHWD) is split into to the two subbaisn and SRCD has a portian of it's area in both subbasins as well. The proposed modification would shift the boundary of the Cosumnes Subbasin north so that all of OHWD and virtually all of SRCD would lie within the Cosumnes Subbasin. 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. The existing GMPs for this area must be reconciled regardless of the determination on the proposed boundary modification as none of the existing GMPs for this region conform to the current or the proposed subbasin boundaries. There appears to be scientific justification for the proposition that the Cosumnes Subbasin does not stop at the Cosumnes River centerline, as currently described, but actually extends northward to the edge of the Cosumnes watershed. 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.
