California's Groundwater Update 2020 (Bulletin 118)

California's Groundwater Update 2020 (CalGW) is California's foremost technical publication on groundwater in the state of California. CalGW, formally known as Bulletin 118, is legislatively mandated by Water Code 12924 to be updated every 5 years by the California Department of Water Resources.

This dataset includes the full publication of CalGW - Update 2020, a link to the new California's Groundwater Live platform and all supporting data used in the creation of the report which was finalized on November 16, 2021. CalGW - Update 2020 consists of an Executive Summary (Highlights) and seven chapters commonly referred to as the Statewide Report. Due to the large file sizes, the Update has been broken into multiple pdf documents for the ease of downloading these large files.
