<br />As with any study of this scope and magnitude, its successful
<br />completion would not have been possible without the assistance and
<br />cooperation of numerous agencies and individuals.! These efforts have
<br />been particularly exemplary in this regard. To those involved, as
<br />noted below, the study staff would like to express its sincere thanks
<br />and appreciation.
<br />
<br />In terms of analyses performed for this assessment, contributions
<br />were made by several entities. Hydrologic modeling of the Colorado
<br />River Basin was accomplished by the U.S. Bureau of Reclamation
<br />(Engineering and Research Center, Denver; Upper Colorado Region, Salt
<br />Lake City; and Lower Colorado Region, Boulder City, Arizona). Supple-
<br />mentary hydrologic modeling of the White and Upper Colorado Main Stem
<br />rivers was performed by Production Automation, Inc., Boulder, Colorado.
<br />Fishery and recreational impacts were analyzed by the U.S. Fish and
<br />Wildlife Service's Cooperative, Instream Flow Service Group, Fort Collins,
<br />Colorado. Recreational use data was collected by the U.S. Heritage
<br />Conservation and Recreation Service, Mid-Continent Region, Denver.
<br />Economic modeling was carried out by the Los Alamos Scientific Laboratory,
<br />New Mexico. An analysis of the potential for improving the efficiency
<br />of water use by irrigated agriculture was provided by the U.S. Soil
<br />Conservation Service (West Technical Service Center), Portland. Estimates
<br />of the monetary costs of wastewater treatment systems for oil shale and
<br />coal gasification facilities were developed by Water Purification Asso-
<br />ciates, Cambridge. Massachuset ts. Finally, the U. S. Geological Surve)'
<br />(Water Resources Division, Colorado District), Denver, in a report
<br />prep~red directly for the U.S. Water Resources Council, performed the
<br />instream water quality analyses which are a part of this overall l3(a)
<br />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
<br />review of an interagency, State-Federal Steering Committee. Represented
<br />on that Corr~ittee were the States of Arizona (Larry Linser, Water Com-
<br />mission), Colorado (Larry Morrill. Water Conservation Board), New Mexico,
<br />(Dave Hale, Interstate Stream Commission), Utah (Barry Saunders, Division
<br />of Water Resources), and Wyoming (Clem Lord, State Engineer's Office).
<br />Federal agencies which actively participated in the Committee's work
<br />included the Department of Agriculture (Sheldon Boone, Soil Conservation
<br />Service, Washington, D.C.), Department of Commerce (Stephen R.L.
<br />McNichols, Region VIII, Denver), Department of Energy (Jack O'Brien,
<br />Denver Project Office), Department of Hcusing and Urban Development
<br />(~yron Eckberg, Region VIII, Denver), Department of the Interior (Ken
<br />Kauffman, Bureau of Reclamation, Engineering and Research Center, Denver),
<br />and the U.S. Environnental Protection Agency (Cene Reetz, Region VIII,
<br />Denver).
