This raster data set represents the evapotranspiration (ET) units delineated using Modified Soil-Adjusted Vegetation Index (MSAVI) in the lower Walker River basin.

This vector data set represents the delineated turf evapotranspiration (ET) unit polygon of the golf course near Hawthorne, Nevada.

This vector data set represents the evapotranspiration (ET) discharge quantification area polygon in the lower Walker River basin.

This vector data set represents the riparian and saltcedar generalized vegetation zone polygons in the lower Walker River basin.

This data release contains geospatial data for the lower Walker River basin from the 2009 publication: Allander, K.A., Smith, J.L., and Johnson, M.J., 2009, Evapotranspiration from the lower Walker River basin, west-central Nevada, water years 2005-07: U.S. Geological Survey Scientific Investigations Report 2009-5079, https://doi.org/10.3133/sir20095079.

The supplemental data presented here contains three raster datasets representing the evapotranspiration (ET) units for northern, southern, and western regions of Harney Basin (raster datasets in .tif format) and one vector dataset of ET-unit observations used to delineate ET units (vector dataset in .shp format). Eleven ET units were identified from ET-unit observations of land cover and include bare soil or playa (1), marsh (2), dry meadow (3), wet meadow (4), open water (5), riparian (6), mixed shrubland (7), phreatophyte shrubland (8), xerophyte shrubland (9), sagebrush shrubland (10), and xerophyte grassland (11). Irrigated areas are excluded from ET units. Unpublished land-cover datasets collected by the U.S. Bureau of Land Management (BLM) and U.S. Fish and Wildlife Service (USFWS) were used, in part, to generate ET-unit observations and are provided (vector datasets in .shp and .csv format) in the sub-child item, Harney Basin Land-Cover Observations.

This vector data set represents the evapotranspiration (ET) station location points in the lower Walker River basin.

These vector data represent the 8-digit hydrologic unit (HU8) polygons used to define the raster processing extent in the Nevada StreamStats study area.

These raster data represent spatially distributed slope percentages in the Nevada StreamStats study area for the period of 2024.
