Use this interactive ETgage map to access weekly information provided by growers, consultants, NRD staff and Extension Educators. To view the data, click on the county you'd like to view the data from. You will then see a GoogleTM Map view of the county that has the ETgage sites marked as balloons, simply click on the balloon near your location. You will then go to a page that includes the weekly ETgage change along with weekly rainfall amounts. The ETgage change along with your crop's stage of growth can be used to estimate your crop's water use.
