Abstract
 Tehama County: A Small Water System's Drought Vulnerability Study Track: Water Resources Author(s): Doti Watkins, Auturo Smith Previous droughts have prompted water supply concerns for small, rural communities' ability to maintain water supplies for sanitation, drinking, and fire fighting needs. Funded by the Department of Water Resources, the Tehama County Flood Control and Water Conservation District (District) initiated a small water systems (SWS) drought vulnerability study. The study inventoried locations of SWS and evaluated the relative degree to which SWS, reliant primarily on groundwater, may be at risk of supply shortages or impacts during droughts. ArcView 8.3 and the ArcView Spatial Analyst extension were used to analyze drought vulnerability factors including future water demands associated with agricultural and urban growth. These tools were also used to estimate drought groundwater levels, as well as graphically represent the SWS drought vulnerability findings. The District will use the GIS project as a planning and management tool to help lessen the likelihood of drought susceptibility for existing and future SWS.
