(A) According to decisions of the courts of 
the State of Colorado, the United States has ex-
isting rights to water within the Rocky Moun-
tain National Park. 
(B) Those rights are sufficient for the pur-
poses of the Wilderness as designated by section 
2. 
(C) In light of the findings in subpara-
graphs (A) and (B), there is no need for this 
Act to effect a reservation by the United States 
of any additional water rights to fulfill the pur-
poses for which the Wilderness is designated. 
(2) NO RESERVATION.—Nothing in this Act or 
any action taken pursuant to this Act shall con-
stitute either an express or implied reservation of 
water or water rights for any purpose. 
(3) NO
EXEMPTION
FROM
STATE
WATER 
LAWS.—Nothing in this Act constitutes an express 
or implied claim or denial on the part of the Federal 
Government as to exemption from State water laws.

Project and its facilities which were allowed as of 
June 1, 1998, shall be allowed to continue and shall 
not be affected by the designation of the land as wil-
derness. 
(2) NEW ACTIVITIES.—In addition to the activi-
ties described in paragraph (1), any other activities 
on, under, or affecting the Wilderness that because 
of emergencies or catastrophic events become nec-
essary for the operation, maintenance, repair, re-
placement, and continued use of the Colorado-Big 
Thompson Project and its facilities shall be allowed, 
subject only to reasonable restrictions which are es-
tablished by the Secretary to protect the wilderness 
values of the land. In implementing this paragraph, 
the Secretary shall not establish any restrictions on 
the activities that would prevent the occurrence of 
such necessary activities or that would reduce the 
water supply provided by the Colorado-Big Thomp-
son Project or the Windy Gap Project. 
(3) RELATION TO AUTHORITY IN ACT ESTAB-
LISHING PARK.—Nothing in the first section of the 
Act of January 26, 1915 (16 U.S.C. 191), shall be 
construed to allow development within the Wilder-
ness of any reclamation project not in existence as 
of the date of enactment of this Act.

(d) NO BUFFER ZONES.—Congress does not intend 
that the designation by this Act of the Wilderness creates 
or implies the creation of protective perimeters or buffer 
zones around the Wilderness. The fact that nonwilderness 
activities or uses can be seen or heard from within the 
Wilderness shall not, of itself, preclude such activities or 
uses up to the boundary of the Wilderness. 
(e) TRAILS.—The Secretary may upgrade trails or 
construct new trails in the Wilderness, including primitive, 
unpaved, and wheelchair-accessible trails. 
(f) PROHIBITION OF CERTAIN USES.—

vided for in this Act, and subject to existing private 
rights— 
(A) no commercial enterprises or perma-
nent roads shall be allowed within the Wilder-
ness; and

and as necessary to meet minimum require-

derness:

essary to control fire, insects, and diseases, in-
cluding the use of mechanized equipment, air-
craft, and motorboats.

(i) IN GENERAL.—The Secretary may 
allow the use of aircraft or other vehicles 
for emergency events, such as search and 
rescue, within the Wilderness.
