<br />ACKNOWLEDGMENTS
<br />
<br />As with any study of this scope and magnitude, 'its successful com-
<br />pletion would not have been possible, without the assistance and cooperation
<br />of numerous agencies and individuals. These efforts have been particularly
<br />exemplary in this regard. To those involved, as noted below, the study
<br />staff would like to express its sincere thanks and appreciation.
<br />
<br />In terms of the analyses performed for this assessment, contributions
<br />were made by several entities. Hydrologic modeling of the Colorado River
<br />Basin was accomplished by the U.S. Bureau of Reclamation (Engineering and
<br />Research Center, Denver; Upper Colorado Region, Salt Lake City; and Lower
<br />Colorado Region, Boulder City, Arizona). Supplementary hydrologic modeling
<br />of the White and Upper Colorado Main Stem rivers was performed by Produc-
<br />tion Automation, Inc., Boulder, Colorado. Fishery and recreational impacts
<br />were analyzed by the Cooperative Instream Flow Service Group, Fort Collins,
<br />Colorado. Recreational use data was collected by the U.S. Heritage Con-
<br />servation and Recreation Service, Mid-Continent Region, Denver. Economic
<br />modeling was carried out by the Los Alamos Scientific Laboratory, New
<br />Mexico. An analysis of the potential for improving the efficiency of
<br />water use by irrigated agriculture was provided by the U.S. Soil Conserva-
<br />tion Service (West Technical Service Center), Portland. Estimates of
<br />the monetary costs of wastewater treatment systems for oil shale and coal
<br />gasification facilities were developed by Water Purification Associates,
<br />Cambridge, Massachusetts. Finally, the U.S. Geological Survey (Water
<br />Resources Division, Colorado District), Denver, in a report prepared
<br />directly for the U.S. Water Resources Council, performed the instream
<br />water quality analyses which are a part of this overall 13(a) assessment.
<br />
<br />In addition to the work undertaken by the above-named organizations,
<br />this study has benefited immeasurably from the input, guidance, and review
<br />of an interagency, State-Federal Steering Committee. Represented on that
<br />committee were the States of Arizona (Larry Linser, Water Commission),
<br />Colorado (Larry Morrill, Water Conservation Board), New Mexico (Dave Hale,
<br />Interstate Stream Commission), Utah (Barry Saunders, Division of Water
<br />Resources), and Wyoming (Clem Lord, State Engineer's Office). Federal
<br />agencies which actively participated in the committee's work included the
<br />Department of Agriculture (Sheldon Boone, Soil Conservation Service,
<br />Washington, D.C.), Department of Commerce (Stephen R. L. McNichols, Region
<br />VIII, Denver), Department of Energy (Jack O'Brien, Denver Project Office),
<br />Department of Housing and Urban Development (Myron Eckberg, Region VIII,
<br />Denver), Department of the Interior (Ken Kauffman, Bureau of Reclamation,
<br />Engineering and Research Center, Denver), and the U.S. Environmental
<br />Protection Agency (Gene Reetz, Region VIII, Denver).
