Modeling the Impacts of Glen Canyon Dam Operations on Colorado River Resources

On this page:

  • Overview
  • Downloads
This is a multidisciplinary scientific report that details how future operations of Glen Canyon Dam will impact the biophysical landscape of Grand Canyon and the Colorado River. The report is being prepared by the USGS and delivered to the U.S. Bureau of Reclamation. The USGS is providing supervisory and peer reviews for the entire report; while this document includes many disciplinary subsections, my work contribution is limited to Section V ("V.    Modeling Impacts of Glen Canyon Dam Operations Scenarios of the Interim Guidelines SEIS and LTEMP SEIS on Sand Exposure for Aeolian Landscape and Cultural Site Resources"). 

Impact/Purpose

Our work uses predictive modeling to forecast how future operations of Glen Canyon Dam on the Colorado River will respond to changing water supplies and ultimately impact the Grand Canyon Ecosystem. Ultimately, this work will aid water managers in planning the sustainable operation of one of America's most vital water storage reservoirs.
