Croyle New Ground Water Legislation
This document summarizes California's ongoing drought conditions and response efforts. It notes that 2014 was one of the driest years on record with low water storage levels statewide. Groundwater supplies are being severely depleted. In response, the state has declared a drought emergency, facilitated water transfers, and implemented conservation measures. Looking forward, state actions focus on sustainable groundwater management, increasing water storage and supply reliability through the water bond, and preparing for potential mandatory conservation if dry conditions continue in 2015.
