  • Comprehensive Walker Lake Basin Overview [PDF]
    Report by Dr. Saxon E. Sharpe, Dr. Mary E. Cablk, and Dr. James M. Thomas
    DRI –May 2007, Revised May 1, 2008

    This report describes physical, hydrological, and biological environments of the Walker Lake Basin. The information is based on current data drawn from peer-reviewed scientific literature, agency data sets and reports, and other published sources. Acronyms, tables, figures and a glossary of key terms are included at the beginning of the report. This document is to be used as a starting point for those interested in learning more about, or conducting research in, the Walker Basin.
  • Overview Walker River Basin Research Program [PPT]
    Presentation by James M. Thomas, Ph.D., Research Professor, Director, Center for Watershed Environmental Sustainability, DRI – March 2008
    The Walker River Basin was the topic of a panel moderated by James Thomas at the annual Nevada Water Resources Association (NWRA) Conference. The panel focused on ongoing hydrologic studies directed by the University of Nevada System of Higher Education and the US Geological Survey.
