EXECUTIVE SUMMARY

INTRODUCTION

In 1981, the Colorado General Assembly authorized the Colorado

Water Conservation Board (CWCB) to conduct studies of four potential water

resources development projects (Section 7, Senate Bill 439). Among these was

the "Una Reservoir -- a dam and reservoir on the Colorado main stem upstream

of the Town of DeBeque with the reservoir extending no further upstream than

to a point just downstream of Parachute Creek" (see Fig. S-1).

The CWCB retained R. W. Beck and Associates to perform the Una
Reservoir Project Study. Expenditures were limited by Senate Bill 439 to
$300,000. In addition, Senate Bill 439 specifies that future funding" is
contingent upon a showing that additional funding is justified based on compe-
tent engineering and economic data."

STUDY OBJECTIVE

The objective of this study was to evaluate, at an appraisal-level
of detail, the engineering feasibility and cost of the Una Dam and Reservoir,
including potential hydroelectric generation facilities. These appraisal-
level engineering studies include:

o An evaluation of the hydrological and sedimentation charac-
teristics of the Colorado River at Una Dam.

o An analysis of the water rights and storable flows available
for Una Reservoir.

o Reservoir operation studies for power development.
