Previous Southern Sacramento Valley ET Reports- October 2022

This report covers the CIMIS stations in Woodland, Davis, Staten Island, and Verona. More information on using ET Reports is available here. Bookmark this page and visit weekly for the most current report.

PLEASE NOTE: Due to the recent closing of the Dixon station and expansion of nut crops in southern Yolo and Solano Counties, we have removed Dixon and added the Staten Island.

Accumulations for prune, walnuts, and vineyards will begin as soon as leafout occurs for the 2022 season and the leafout date will be noted in parentheses next to the crop.tion (242, near Walnut Grove) to these reports.
Estimates are for orchard floor conditions where vegetation is managed by some combination of strip applications of herbicides, frequent mowing or tillage, and by mid and late season shading and water stress. Weekly estimates of soil moisture loss can be as much as 25 percent higher in orchards where cover crops are planted and managed more intensively for maximum growth.

The amount of water required by a specific irrigation system to satisfy evapotranspiration. Typical ranges in irrigation system efficiency are: Drip, 80%-95%; Micro-sprinkler, 80%-90%; Sprinkler, 70%-85%; and Border-furrow, 50%-75%.
