The Columbia River Basin Evapotranspiration Project is a multi-state collaboration to improve water management with easy access to satellite-based ET data and mapping tools.

Groundwater evapotranspiration (ETg) from phreatophyte vegetation is the primary component of natural groundwater discharge within the Humboldt River Basin. This report summarizes previous study estimates of ETg, and details methods and results of updated groundwater discharge areas, ETg rates, and ETg volume estimates developed in this study.

Project Description Groundwater supports a variety of ecosystems in Nevada and the Great Basin, including springs, rivers, lakes, meadows, and wetlands, as well as trees and shrubs that tap into groundwater through deep roots (called phreatophytes). Many of these...

The study summarizes ET from agricultural areas in northwest Nevada and northeast California from 2001-2011 from remote sensing.

Project Description Maintaining the ecological integrity of riparian areas and other groundwater-dependent ecosystems (GDEs) is an important objective for natural resource and water managers, given the role of these systems in sustaining biodiversity and the other...
