text: SECTION 1. SHORT TITLE AND PURPOSE.
  
      (a) Short Title.--This Act may be cited as the ``Rocky Mountain 
  National Park Wilderness and Indian Peaks Wilderness Expansion Act''.
      (b) Purpose.--The purpose of this Act is to include in the National 
  Wilderness Preservation System certain lands within the Rocky Mountain 
  National Park, Colorado, in order to protect the enduring scenic and 
  historic wilderness character and unique wildlife values of the lands 
  as well as the scientific, educational, inspirational, and recreational 
  resources, values, and opportunities of the lands; and to adjust the 
  boundaries of the Indian Peaks Wilderness and the Arapaho National 
  Recreation Area on the Arapaho National Forest in Colorado.
  
  SEC. 2. DESIGNATION OF ROCKY MOUNTAIN NATIONAL PARK WILDERNESS.
  
      (a) Designation.--In furtherance of the purposes of the Wilderness 
  Act (16 U.S.C. 1131 et seq.), certain lands within the Rocky Mountain 
  National Park, Colorado, which comprise approximately 249,339 acres, as 
  generally depicted on the map titled ``Rocky Mountain National Park, 
  Colorado Wilderness Boundaries'' and dated February 2006, are hereby 
  designated as wilderness and, therefore, as a component of the National 
  Wilderness Preservation System. The designated lands shall be known as 
  the Rocky Mountain National Park Wilderness.
      (b) Map and Description.--
              (1) Preparation and submission.--As soon as practicable 
          after the date of the enactment of this Act, the Secretary of 
          the Interior shall prepare a map and a boundary description of 
          the Rocky Mountain National Park Wilderness designated by 
          subsection (a) and file the map and boundary description with 
          the Committee on Resources of the House of Representatives and 
          the Committee on Energy and Natural Resources of the Senate. 
          The map and boundary description shall be on file and available 
          for public inspection in the office of the Director of the 
          National Park Service, Department of the Interior.
              (2) Treatment.--The map and boundary description prepared 
          under paragraph (1) shall have the same force and effect as if 
          included in this Act. The Secretary of the Interior may correct 
          clerical and typographical errors in the map and description.
      (c) Potential Wilderness Lands.--
              (1) Definition.--In this section, the term ``potential 
          wilderness lands'' means--
                      (A) lands identified as potential wilderness on the 
                  map referred to in subsection (a); and
                      (B) lands and interests therein acquired by the 
                  United States on or after the date of the enactment of 
                  this Act that are located within the boundaries of the 
                  Rocky Mountain National Park and are contiguous with 
                  lands designated as wilderness by this Act.
              (2) Inclusion in wilderness.--Upon publication in the 
          Federal Register of a notice by the Secretary of the Interior 
          that all uses of a parcel of potential wilderness lands 
          inconsistent with the Wilderness Act have ceased, the parcel 
          shall be included in the Rocky Mountain National Park 
          Wilderness designated by subsection (a) and managed as provided 
          in section 3. The Secretary of the Interior shall modify the 
          map and boundary description prepared under subsection (b) to 
          reflect the inclusion of the parcel in the Rocky Mountain 
          National Park Wilderness.
      (d) Exclusion of Certain Lands.--The boundaries of the Rocky 
  Mountain National Park Wilderness and the potential wilderness lands 
  specifically exclude the following:
              (1) The Grand Ditch (including both the main canal of the 
          Grand Ditch and a branch thereof known as the specimen Ditch) 
          and its right-of-way as well as associated appurtenances, 
          structures, buildings, camps, and worksites in existence as of 
          June 1, 1998.
              (2) Lands owned by the St. Vrain & Left Hand Water 
          Conservancy District, including Copeland Reservoir and the 
          Inlet Ditch to such reservoir from the North St. Vrain Creek, 
          amounting to approximately 35.38 acres.
              (3) Lands owned by the Wincentsen-Harms Trust, amounting to 
          approximately 2.75 acres.
              (4) Lands within the area depicted as ``East Shore Trail 
          Area'' on the map described in subsection (b).
      (e) East Shore Trail Area.--
              (1) Alignment line and trail.--
                      (A) Not later than one year after the date of the 
                  enactment of this Act, the Secretary shall establish an 
                  alignment line for a trail, to be known as the East 
                  Shore Trail, located within the East Shore Trail Area, 
                  to maximize the opportunity for sustained use of the 
                  trail without harm to affected resources or conflicts 
                  among users. After establishing the alignment line, the 
                  Secretary shall identify the boundaries of the trail, 
                  but the trail shall not extend more than 25 feet east 
                  of the alignment line or be located within the Rocky 
                  Mountain National Park Wilderness.
                      (B) Nothing in this Act shall be construed to 
                  require the construction of a trail along the alignment 
                  line established pursuant to this paragraph or to limit 
                  the extent to which any otherwise applicable laws or 
                  policies shall apply with respect to any decision 
                  regarding construction of such a trail.
              (2) Map adjustment.--After establishing the alignment line 
          of the East Shore Trail, the Secretary shall adjust the map of 
          the wilderness area designated by subsection (a) so that the 
          western boundary of the wilderness is 50 feet east of the 
          alignment line.
              (3) Other adjustments.--To the extent necessary to protect 
          National Park resources, the Secretary from time to time may 
          adjust the boundaries of the East Shore Trail, but no 
          adjustment shall have the effect of placing any portion of such 
          trail within the boundary of the wilderness area.
              (4) Time limitation for authorization of use by 
          nonmotorized bicycles.--If the East Shore Trail has not been 
          constructed and authorized for use by nonmotorized bicycles on 
          or before the date that is 25 years after the date of the 
          enactment of this Act, the East Shore Trail Area shall be 
          included in the Rocky Mountain National Park Wilderness 
          designated by subsection (a) and managed as provided in section 
          3, and the Secretary shall modify the map and boundary 
          description of such wilderness area to reflect the inclusion of 
          such lands in wilderness.
      (f) Relation to Lands Outside Wilderness.--
              (1) Use of lands.--Except as provided in this subsection, 
          nothing in this Act shall affect the management or use of any 
          lands not included within the boundaries of the Rocky Mountain 
          National Park Wilderness or the potential wilderness lands.
              (2) Use of motorized vehicles.--Until the date that is 25 
          years after the date of the enactment of this Act, no use of 
          motorized vehicles or other motorized machinery not permitted 
          on March 1, 2006, shall be allowed in the East Shore Trail 
          Area, except as may be necessary for constructing or 
          maintaining the East Shore Trail, if such construction is 
          authorized by the Secretary.
              (3) Management of pending wilderness.--Pending their 
          inclusion in wilderness pursuant to subsection (c)(2), the 
          potential wilderness lands shall be managed to protect any 
          wilderness characteristics and to maintain their suitability 
          for inclusion in wilderness.
  
  SEC. 3. MANAGEMENT OF ROCKY MOUNTAIN NATIONAL PARK WILDERNESS.
  
      (a) Management Generally.--Subject to valid existing rights, lands 
  designated as wilderness by section 2(a) or subsequently included in 
  the Rocky Mountain National Park Wilderness by section 2(c) shall be 
  managed by the Secretary of the Interior in accordance with the 
  Wilderness Act (16 U.S.C. 1131 et seq.) and this Act. With respect to 
  the lands designated as wilderness by section 2(a), any reference in 
  the Wilderness Act to the effective date of the Wilderness Act shall be 
  deemed to be a reference to the date of the enactment of this Act. With 
  respect to the lands subsequently included in the Rocky Mountain 
  National Park Wilderness by section 2(c), any reference in the 
  Wilderness Act to the effective date of the Wilderness Act shall be 
  deemed to be a reference to the date on which the lands were included 
  in the wilderness area.
      (b) Water Rights.--
              (1) Findings.--Congress finds the following:
                      (A) According to decisions of the courts of the 
                  State of Colorado, the United States has existing 
                  rights to water within the Rocky Mountain National 
                  Park.
                      (B) Those rights are sufficient for the purposes of 
                  the Rocky Mountain National Park Wilderness as 
                  designated by section 2.
                      (C) In light of the findings in subparagraphs (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 purposes for which the 
                  Rocky Mountain National Park Wilderness is designated.
              (2) No reservation.--Nothing in this Act or any action 
          taken pursuant to this Act shall constitute either an express 
          or implied reservation of water or water rights for any 
          purpose.
      (c) Colorado-Big Thompson Project.--
              (1) Current activities.--Activities on, under, or affecting 
          the lands designated as wilderness by section 2 relating to the 
          monitoring, operation, maintenance, repair, replacement, and 
          use of the Colorado-Big Thompson 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 
          lands as wilderness.
              (2) New activities.--In addition to the activities 
          described in paragraph (1), any other activities on, under, or 
          affecting the lands designated as wilderness by section 2 that 
          because of emergencies or catastrophic events become necessary 
          for the operation, maintenance, repair, replacement, and 
          continued use of the Colorado-Big Thompson Project and its 
          facilities shall be allowed, subject only to reasonable 
          restrictions which are established by the Secretary of the 
          Interior to protect the wilderness values of the lands. 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 Thompson Project 
          or the Windy Gap Project.
              (3) Relation to authority in act establishing 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 
          lands designated as wilderness by section 2 of any reclamation 
          project not in existence as of the date of the enactment of 
          this Act.
      (d) No Buffer Zones.--Congress does not intend that the designation 
  by this Act of the Rocky Mountain National Park Wilderness creates or 
  implies the creation of protective perimeters or buffer zones around 
  the wilderness area. The fact that nonwilderness activities or uses can 
  be seen or heard from within the wilderness area shall not, of itself, 
  preclude such activities or uses up to the boundary of the wilderness 
  area.
