Basin Notes
Fish Slough was included as an independent groundwater basin in Bulletin 118 (DWR, 1975) and Bulletin 118-80 (DWR, 1980), but dropped from Bulletin 118-2003 (DWR, 2003) on the reasoning that “Granite Mountain Area (6-59) and Fish Slough Valley (6-60) groundwater basins have been deleted because no information was found concerning wells or groundwater in these basins or because well completion reports indicate that groundwater production is derived from fractured rocks beneath the basin.” Shallow cores from Fish Slough show alluvium is a thin veneer on the order of ten feet atop Bishop Tuff. — Hydrogeologic Conceptual Model for the Owens Valley Groundwater Basin (6-12), Inyo and Mono Counties by Robert Harrington
