Patten Center for Environmental Studies Bonnie Turner Center for Environmental Studies Arizona State University Tempe, Arizona 85287 A report submitted in partial fulfillment of U.S. Army Corps of Engineers Contract DACW09-83-M-2623. April 1984 EXECUTIVE SUMMARY A detailed analysis of the published results of the U. S. Geological Survey Phreatophyte Project conducted in the area of interest for the Corps of Engineers Camelsback Dam study provides the following results. It appears that the figure of 18.53 inches per year for water savings from phreatophyte clearing along the Gila River in southeast Arizona should not be used for predicting potential water salvage because of large sampling errors, measurement errors, and the inherent variability of the natural processes of evapotranspiration.
