About This Data This water footprint represents California consumptive water use (green + blue water) used to grow Lettuce (Romaine), based on Mekonnen & Hoekstra (2011) water footprint data regionalized to California and USDA yield figures (2022 production year). Values are production-weighted statewide averages across 5 producing counties and 66,210 harvested acres. These figures are consumptive (green + blue) and exclude grey pollution-dilution water. Global average water footprints are typically higher, as California tends to be more water-efficient than the world average.
