A Water Geochemistry Study of Indian Wells Valley, Inyo and Kern Counties, California. Supplement. Isotope Geochemistry and Appendix H.

Abstract

Hydrogen and oxygen isotope data on waters of Indian Wells Valley, the Sierra, Rose Valley, and Coso thermal and nonthermal waters were studied. The isotope ratios of Sierran waters are a function of latitude with both ratios becoming depleted in the heavier isotopes from south to north. Assuming that groundwater recharge is from the Sierra, recharge areas for the various groundwater types can be designated. Hydrogen and oxygen isotopes do not uniquely define the recharge area for the Coso geothermal system but strongly suggest Sierran recharge with perhaps some local recharge. Sierran recharge is best supported by structural features and stream flow characteristics in the Sierra. Coso geothermal brines may have a component of waters from several different past pluvial periods, but the volume and midfield recharge rate of the system suggest continuous recharge.
