• The West San Jacinto Groundwater Sustainability Agency (WSJGSA) for the western portion of the San Jacinto Groundwater Basin is the Eastern Municipal Water District (EMWD). Please be advised that the WSJGSA intends to request modifications of the boundary of the San Jacinto Groundwater Basin, Department of Water Resources (DWR) Bulletin 118 Basin No. 8-005 (Basin). The modification request is to eliminate areas of the existing Basin that lack viability and/or contribution to the local groundwater aquifer system. The modified boundary will cover areas underlain by permeable materials capable of providing significant quantities of groundwater to wells; eliminate areas underlain by the consolidated bedrock described as having very low water-yielding capability; and exclude areas that do not align with the DWR?s definition of an alluvial basin. The proposed Basin boundary will coincide with the surface extent of unconsolidated young alluvium, old alluvium, alluvial fan, valley fill deposits, and other geologic formations having well understood and documented groundwater significance as mapped by the California Geological Survey. The proposed modification will not impact the sustainable management of the Basin because the areas identified for removal do not provide a significant source of water nor significant volumes of groundwater and there is no current or planned use for these areas that would constitute a significant contribution to water resources.
