    • Geospatial Data to Support Estimates of Annual Groundwater Discharge by Evapotranspiration from Areas of Spring-Fed Riparian Vegetation, Stump Spring and Hiko Springs, Clark County, southern Nevada

    Metadata Updated: July 6, 2024

    This USGS data release, supporting USGS Scientific Investigations Report 2020-5075, Estimates of Groundwater Discharge by Evapotranspiration, Stump Spring and Hiko Springs, Clark County, Southern Nevada, 2016–18, consists of five datasets - Normalized Difference Vegetation Indexes (NDVI) and a mapped groundwater discharge areas (GDA) for two spring areas, and a two-class land cover classification for Stump Springs and the Area of Critical Environmental Concern (ACEC) adjacent to Stump Springs. The mapped GDAs are the area within each spring’s riparian area where discharge from evaporation by open water or bare soil and transpiration from phreatophytic plants exceeds the volume of water contributed by precipitation. The GDAs were delineated from visual interpretation of 2015 National Agricultural Imagery Program (NAIP) imagery and 2016 and 2017 WorldView 2 imagery. The WorldView 2 imagery, NDVI based on the Worldview 2 imagery, and two-class land cover classification each were used to estimate the area of riparian vegetation within the GDA.
