Total Withdrawal (gallons/day)
Each county of California has been assigned a shade, corresponding to the amount of total water withdrawals. The numerical values corresponding to the shades have been defined in the legend in millions of gallons per day. To compare water use and population demographics, click on any of California’s 58 counties. In the charts, water withdrawal has been defined in gallons per day. (Scale is not constant, so always make note of it.) Water withdrawals have been broken down into sectors denoted agricultural, industrial/commercial/other, and domestic. To see how trends in California have been affected by time, adjust the year of interest with the buttons at the top.
