~f williams Fork Reservoir is not available to serve its historic
function, the Secretary of the Interior, through Reclamation,
would have the opportunity to review and approve any proposed
substi tution or exchange related to the availability of ~'lilliarns
Fork ReserJoir on a case-ny-case basis.

2. Responsibility for establishing conditions under which a
substitution made possible by the agreement, referenced in Item
VI.A.I. above, will be implemented, and for ensuring appropriate
NEPA compliance if future substitutions or exchanges are
authorized which have impacts different from those disclosed in
the FEIS. The Colorado Water Conservation Board (CWCB) holds an
~nstrearn flow decree (87~fl293) for 50 cubic feet per second (cfs)
or the inflow into Dillon Reservoir, whichever is less, on the
Blue River below Dillon Darn. Approval of water substitutions by
Reclamation shall be contingent upon the maintenance by Denver of
a release below Dillon Darn to the Blue River of not less than 50
cfs to a maximum 1,000 acre-feet in excess of the inflow into
Dillon Reservoir during the year following the request and
approval of such substitution. Additionally, Reclamation
oenerally maintains releases to the Blue River below Green
Mountain Darn at rates of discharge that are equal to or greater
than those incorporated in the instrearn flow decree (87CW299l
obtained by the CWCB. The decreed rates of discharge are 60 cfs
(May 1 through July 15) and 85 cfs (July 16 through April 30)
No water substitution will be approved that would cause the
releases from Green Mountain Darn to be less than the
aforementioned instrearn flows.

3. Responsibility for ensuring an annual public disclosure
of proposed Wolford Mountain Reservoir operations. This
disclosure can be provided in association with the annual public
involvement activities for the Ruedi Reservoir-Green Mountain
Reservoir endangered species conservation releases for instream
flows. The meetings will include concerned Federal, State, and
local government agencies, and other involved parties including
the public, water users, and special interest groups. Agency
input and public comments will be addressed within the
operational constraints, demands, and the flexibility of the
water management agencies.
