CHAPTER I

INTRODUCTION

Section 1: Author iza tion

This report, prepared by PRC Engineering, Inc" provides the results of an irrigation
improvement study for the Tongue Creek basin, The area studied by PRC
Engineering encompassed the tributary basin of the Gunnison River in Delta
County, Colorado, A project location map is given on Figure 1-1,

Sponsors for the Grand Mesa Water Supply Study included:

o Colorado Water Conservation Board (CWCB)
o Grand Mesa Water Conservancy District (GMWCD)
o Colorado River Water Conservation District (CR WCD)

A contract between the sponsors and PRC Engineering, which specified the study's
terms, conditions and responsibilities of sponsors and consultants, was signed and
entered into effect on August 15, 1985,

The 1986 Grand Mesa Water Supply study conducted by PRC Engineering was
initiated by local interest groups and Colorado State Government to formulate a
plan of improvements which could be implemented without a major input by the
federal government. Earlier studies by the U,S. Bureau of Reclamation (USBR)
formulated plans which, if implemented, would have been primarily federal
projects, but none of the USBR plans were implemented.

Section 2: Scope of Work

As a result of this study, PRC Engineering developed alternative basin development
plans. The plans consist mainly of constructing a reservoir and appurtenant works
