! to benefit the Navajo Nation.

Water stored in Ridges Basin Reservoir will be released as
, necessary back to the Animas River for municipal and industrial
users within Colorado and New Mexico. Water could also be
pumped from the reservoir and conveyed to rural areas west of
Durango, however necessary facilities to pump and convey the
. water will have to be provided by others. The reservoir will also
. include an inactive pool of approximately 30,000 acre-feet for
recreational, fishery, and water quality purposes. Recreation
facilities to support public use of the reservoir are expected to
; also be provided by others.

,The nonstructural component of the project is the Tribal
, Resource Funds for use by the Ute Mountain Ute and Southern
,Ute Indian Tribes, respectively, for protection, acquisition,
; enhancement, or development of natural resources for the
i benefit of the Tribes and their members. The use of the funds
! shall be governed by an approved economic development plan
! provided by each Tribe.

Project Financing

The Colorado Ute Settlement Act Amendments of 2000
provide that project costs allocated to the three benefitting
Indian Tribes are non-reimbursable (The Indian Tribes will
not pay any of the construction costs of the project). The
project costs allocated to the non-Tribal participants are
reimbursable and may be satisfied upon the payment in full
ofthe non-Tribal water capital obligations prior to initiation of
construction. However, the non-Tribal capital obligations will
be subject to a final cost allocation upon project completion
and may warrant additional payment. Certain project costs
allocated to recreation, cultural resources, and fish and
wildlife mitigation are non-reimbursable consistent with
Federal Reclamation law.
