| contents | <p><strong>ET Data for Quantifying and Demonstrating Potential Water Resource Benefits of Improved Irrigation Efficiencies in Sierra Valley, California</strong></p> <p>This Zenodo record publishes evapotranspiration (ET) datasets for Sierra Valley, California, developed to support field-scale and basin-scale evaluation of irrigation efficiency, applied water, and groundwater evapotranspiration (ETg). The package includes an OpenET/ET-Demands applied-water dataset for agricultural fields and a Beamer-Minor Method (BMM) ETg dataset for ET Units and basin-scale ETg summaries. These data support analysis of baseline consumptive use in irrigated agriculture and groundwater-dependent ecosystems (GDEs), and evaluation of potential water-resource benefits associated with improved irrigation efficiency.</p> <p>The deposit is organized under the package root folder <strong><code>DRI_SierraValleyCA_ET_DataPackage</code></strong> and includes two primary data packages (Feb 2026 snapshot):</p> <h3>1) OpenET / ET-Demands Applied Water</h3> <p>Located in: <code>OpenET_ET_Demands_AppliedWater/</code></p> <p>This package contains:</p> <ul> <li> <p><strong>Agricultural field boundary shapefile</strong>: <code>AgriculturalFieldBoundaries_Stetson_CADWR_Merged_Feb2026.*</code><br>Polygon boundaries for agricultural fields used for field-scale ET and applied-water accounting.
