<br />000753 <br /> <br />Colorado. A display at Cimarron depicts the rise and fall of the narrow gauge railroad as a <br />mountain transportation system, <br /> <br />The lowering of Morrow Point Reservoir to a water surface elevation of 7.129 ft. may expose <br />portions of the old Cimarron Narrow Gauge railroad bed that have been underwater since the <br />filling of Morrow Point Reservoir. Morrow Point Reservoir may be closed to the public between <br />September 41h and October I st for public safety; therefore, the railroad bed would be protected <br />when exposed, No other known historic or archeological sites occur within the reservoir high <br />water line. <br /> <br />Indian Trust Assets <br /> <br />Indian trust assets are legal interests in property held by the United State for Indian Tribes or <br />individuals. Reclamation and other Federal agencies share the responsibility to protect these <br />assets, There have been no trust assets identified in the project area, and therefore no impact on <br />these assets is predicted, <br /> <br />Environmental Justice <br /> <br />Executive Order 12898 on Environmental Justice provides that Federal agencies analyze <br />programs to assure that they do not disproportionately adversely affect minority or low income <br />populations or Indian Tribes. There are no potentially affecled minority or low income <br />populations in the project area and no adverse effects related to environmental justice are <br />predicted. <br /> <br />Socioeconomic <br /> <br />Socioeconomic resources related to the proposed action can be broken into two general <br />categories: I) Hydropower Production from the Aspinall Unit and 2) Commerical Guiding <br />Services for fishing and float guides. <br /> <br />Hvdropower Production <br /> <br />The Aspinall Unit is operated to meet base demand and daily peak power demands and reserve <br />criteria. and the Western Area Power Administration (W APA) markets the power. Peaking <br />power means that higher releases are made at those times during the day when energy demands <br />are highest. Part of Blue Mesa and Morrow Point Dam releases are made to meet peak power <br />demands, This results. at times, in more frequent flow changes Blue Mesa and Morrow Point, <br />and between Morrow Point Reservoir and Crystal Reservoir. <br /> <br />Crystal Reservoir is operated differently than the other two reservoirs. Crystal Reservoir <br />provides storage space for smoothing peaking power releases from Morrow Point Reservoir to <br />meet the relatively uniform river flows required to provide the existing Uncompaghre Project <br /> <br />17 <br />
