<br />Ou1538 <br /> <br />Scope <br /> <br />Land and Facility Resources <br /> <br />Protect Existing Structures - The nearby highway, railroad, and siphon were designed and <br />constructed with the dam in place. Evaluating the effect of the alternatives on integrity and use <br />of these structures is necessary. <br /> <br />Railroad and Landslide Stability - The fish passage alternatives could affect the stability of an <br />existing landslide and railroad. Union Pacific Railroad tracks run along the Colorado River past <br />the Price-Stubb Dam. The landslide has previously caused damage to the tracks. <br /> <br />Ownership of Dam and Lands - Before any modifications to the dam and site could be made, <br />permission would be needed from the dam owners and land owners to access the site and/or use <br />their land and facilities. <br /> <br />Unique Geographical Features <br /> <br />Floodplain and Wetlands Protection - The Colorado River provides highly valued riparian <br />habitat and floodplain functions that need to be considered as fish passage is restored. <br /> <br />Fish and Wildlife Resources <br /> <br />Effects on Endangered Colorado River Fishes - Providing passage at the dam is needed to <br />allow endangered fish access to upstream habitat (see background information on page 3). <br />Passage actions should complement other Recovery Program efforts such as stocking endangered <br />fish, controlling competition or predation by nonnative fish, and restoring habitat. <br /> <br />Cultural Resources <br /> <br />Protect Historic Dam - The Price-Stubb Diversion Dam is eligible for listing on the National <br />Register of Historic Places, and Federal agencies are responsible for ensuring their actions do not <br />adversely affect the historic qualities of the dam. <br /> <br />Social and Economic Resources <br /> <br />Hydropower - The Price-Stubb Dam could be used to generate hydroelectric power. Fish ladder <br />alternatives may reduce potential revenues from power generation, and dam removal would <br />preclude hydropower development. <br /> <br />Costs and Benefits - Some people question using taxpayers' money to provide passage for <br />endangered fish. <br /> <br />5 <br />
