Water Budget Data Finder
Irrigation professionals using the WaterSense Landscape Water Budget Tool may use the Water Budget Data Finder to determine peak watering month and the appropriate evapotranspiration and rainfall values for a specific United States zip code.
Information presented in the Data Finder comes from the World Water and Climate Atlas, a project of the International Water Management Institute (IWMI). EPA would like to thank IWMI for the use of this data.
