Service Description: Water depletion is a measure of the fraction of available renewable water consumptively used by human activities within a watershed. Our characterization of water depletion uses calculations from WaterGAP3 to assess long-term average annual consumed fraction of renewably available water, then integrates seasonal depletion and dry-year depletion, also based on WaterGAP3 calculations, with average annual depletion into a unified scale. There are 8 water depletion categories: <5% depleted, 5-25% depleted, 25-50% depleted, 50-75% depleted, dry-year depleted, seasonally depleted, 75-100% depleted, and >100% depleted. For data reliability reasons, we include only the 15,091 watersheds larger than 1,000 km2, which constitute 90% of total land area. A large number of small coastal watersheds are excluded. Detailed information can be found in the open-access paper “Water Depletion: An improved metric for incorporating seasonal and dry-year water scarcity into water risk assessments” online at Elementa: Science of the Anthropocene
