['c:

. a site visit on May 30, 2001, in the presence of Mr. Robert Taylor whose family
has owned the property in Long Hollow for many decades,

. a preliminary review of readily available geology publications for the dam and
reservoir area and two U.S. Bureau of Reclamation (USBR) dam site
investigations within ten miles of the site, and

. WWE's experience on similar projects and knowledge of the La Plata River
basin.

The objective ofthis study is to investigate the technical, financial and institutional
aspects of a limited number of alternative dam and reservoir configurations to identifY
any fatal flaws that could make the construction of a dam and reservoir at this site
infeasible. While the technical problems that may be encountered are difficult to
determine at this time, the feasibility study will clarifY potential problems and the extent
to which they can be resolved.

The value of a dam and reservoir at this site has previously been established (Western La
Plata County Water Management and Conservation Plan) and is multi-faceted. A Long
Hollow dam will have statewide significance through:

. improving administration ofthe La Plata River Compact with New Mexico
(C.R.S. &37-63-101, et seq.),

. improving deliveries thereunder to New Mexico,

. allowing additional Colorado water to be used within Colorado for irrigation and
other uses, and

. lessening the potential for interstate Compact litigation (New Mexico reported to
threaten litigation on an annual basis as a result of alleged problems-in
Colorado's delivery of Compact regulated water).

Construction of this dam and reservoir can be expected to improve the currently
inadequate water supplies in this basin.

The scope of the feasibility study of the proposed Long Hollow dam and reservoir,
separated into phases, will be as follows:

Phase I - Initial Feasibility (Fatal Flaw) Analysis

. Review existing data to obtain an understanding of the requirements for design
and construction of a dam and reservoir.
