records and water rights information were also collected as part of
the initial phase of the study.

Potential water storage sites were established by a review of the
mapping and existing studies. An on-site geological reconnaissance
investigation was performed for each of these sites. Area-capacity
curves, dam layouts, spillway layouts, quantity estimates and,
finally, cost estimates were done for three reservoir sizes at each of
the 12 sites. Cost estimates were also prepared for various canal
enlargements, and extensions. These dams, reservoir and conveyance
systems were then used as building blocks to define various alter-
native project configurations.

The operation of potential project configurations was simulated
using a computer program which provided an estimate of the shortage of
irrigation water in the service area. The effectiveness of various
project configurations was examined by comparison of the shortages.

The costs for various project configurations were combined with
the shortage reductions (yields) to examine the cost effectiveness of
various combinations of reservoir sizes and canal configurations.
From these results certain project configurations were selected.
These are presented as the results of this report, along wi th the
assumptions used in their development.

Throughout the duration of this study Hydro-Triad, Ltd. has con-
ferred with the CRWCD and the CWCB through status meetings and monthly

reports. Major assumptions used in the study were made jointly. The
WDWCD was provided the opportunity to participate during several
public meetings.

This report presents, not one, but several project configurations
which are different because of the different assumptions made in their
development. These assumptions are general in nature, and reflect
varying levels of future development as well as a range of values of
agricultural water. The final selection of a single project con-
figuration is beyond the scope of this study.
