Grape Weekly ET Reports
2018 Weekly ET Reports
The California Department of Water Resources and the University of California Cooperative Extension have teamed up to provide Weekly ET Reports to agricultural water users. Reports include water use information for a variety of crops. Reports will be posted every Friday or Saturday for next week's guidelines.
Weekly ET Reports for grapes use raisin grape (7' x 11' vine/row spacing with 566 vines/acre) and wine grape (7' x 10' vine/row spacing with 622 vines/acre on "California Sprawl" trellis) as examples. Acre-inch and gallons per vine will be reported this year. Growers might apply differently according to the vine/row spacing and trellis type in your vineyard.
