CHAPTER 3
ALTERNATIVES
3.1 INTRODUCTION
This section provides a detailed description of each alternative considered in Phase 1 of this
investigation, based on currently available information. It must be emphasized that the objective
of the Phase 1 investigation is to screen a relatively long list of alternatives and produce a short
list of alternatives which will be studied in greater detail in Phase 2. Where data and information
gaps exist, these gaps are noted and recommendations made for follow-up investigations in
Phase 2 for those alternatives not screened out during the Phase 1 investigation. Unless
' inapplicable to the specific alternative, the following topics are covered for each of the
alternatives to the extent that existing data and information allows:

?J

• Description of the alternative: (1) project operation, (2) physical layout and location of
all project facilities, and (3) existence of channel flow capacity constraints affecting
project operation/feasibility.
• Source of water.
• Necessary water rights and discussion of how these water rights will be obtained.
• Total volume of water made available.
• Feasibility of using water from this specific alternative to augment flows during the 7 to
10-day peak spring runoff flow period.
• Frequency/dependability with which the water can be delivered.
• Feasibility of carrying over unused water from year-to-year.
• Capital and operation and maintenance costs.
• Potential effects of the specific alternative on yields from this and other existing projects,
i.e., would implementation of the specific alternative reduce the yield of other projects.
• Effect of alternative on this and other existing projects' operational flexibility or
reliability.
• Effect of alternative on this and other existing projects' operations and maintenance costs.
• Discussion of how the water available from this alternative will be administered during
the late summer and fall.
• Discussion of any potential legal problems other than water rights and permitting
concerns, such as rights of way, Colorado River Compact Problems, Blue River Decree
concerns, necessity of new Federal or state legislation, etc.
