To further assess the use of stable isoto pes as a tool for identifying recharge sources and to gain an improved und erstanding of groundwater recharge in central Butte County, the Butte Coun ty Department of Water and Resource Conservation implemented the Stable Is otope Recharge Study (Brown &\; Caldwell, 2017). The initial phases of the Stable Isotope Recharge Study included review of existing isotope data in Butte County, along with preparation of a Field Sampling and Analysis Plan to obtain stable isotope data from 30 groundwater wells at 10 individ ual locations and from 10 separate surface-water locations along creeks an d rivers. Samples were collected by Butte County staff in October 2015, Ju ne 2016, October 2016 and March 2017. Thus, samples were collected near th e end of an historic drought period in 2015, at the end of seasonally wet and dry periods in 2016, and during one of the wettest winters on record i n early 2017. Key findings of the Study relate to isotopic variation by se ason in surface water, isotopic variation by area in groundwater, identifi cation of the primary source water regions for recharge, and recognition o f differing recharge mechanisms in different areas of the basin. Within th e main surface water bodies, stable isotope abundance varies seasonally in the creeks that flow into the Valley from the watersheds to the east (e.g . Butte Creek, Big Chico Creek, Little Chico Creek).\r\nSPEAKER BIO:\r\nDr . Andrew A.

Preliminary evaluation of st able isotope data as part of a study of recharge mechanisms for the Lower Tuscan Aquifer (Brown &\; Caldwell, 2013) indicated that use of stable isotopes may provide important insights into the sources of runoff within surface streams and subsequent groundwater recharge pathways within Butte County. To further assess the use of stable isotopes as a tool for identif ying recharge sources and to gain an improved understanding of groundwater recharge in central Butte County, the Butte County Department of Water an d Resource Conservation implemented the Stable Isotope Recharge Study (Bro wn &\; Caldwell, 2017). The initial phases of the Stable Isotope Rechar ge Study included review of existing isotope data in Butte County, along w ith preparation of a Field Sampling and Analysis Plan to obtain stable iso tope data from 30 groundwater wells at 10 individual locations and from 10 separate surface-water locations along creeks and rivers. Samples were co llected by Butte County staff in October 2015, June 2016, October 2016 and March 2017. Thus, samples were collected near the end of an historic drou ght period in 2015, at the end of seasonally wet and dry periods in 2016, and during one of the wettest winters on record in early 2017. Key finding s of the Study relate to isotopic variation by season in surface water, is otopic variation by area in groundwater, identification of the primary sou rce water regions for recharge, and recognition of differing recharge mech anisms in different areas of the basin. Within the main surface water bodi es, stable isotope abundance varies seasonally in the creeks that flow int o the Valley from the watersheds to the east (e.g. Butte Creek, Big Chico Creek, Little Chico Creek).
