<br />, <br /> <br />. <br />. PRELIMINARY. <br />SUBJECT TO REVISTo(~ <br /> <br />a <br />C-) <br />(::., <br />eo <br />CD <br />w <br /> <br />the known range of the bald eagle (Haliaeetus lellcoc"phall1s). Any assessment <br /> <br /> <br />of the effects of the project on. bald eagles will be developed. No species <br /> <br /> <br />listed as endangered by the State of Colorado are known to occur in the area. <br /> <br />3. Modification of existing dam features at John Martin Reservoir for the <br /> <br /> <br />development of hydroelectric power will not affect cultural resources. <br /> <br /> <br />Construction of the transmission line may potentially affect cultural <br /> <br /> <br />resources. All Corps fee lands at John Martin have been inventoried for <br /> <br /> <br />cultural resources and no known archaeological sites are located near the <br /> <br /> <br />project area. Areas outside the Corps fee land boundary have not been <br /> <br /> <br />surveyed. Prior to construction. the transmission line route and any other <br /> <br /> <br />previously unsurveyed areas subject to ground disturbance activities as a <br /> <br /> <br />result of this project will be surveyed by a qualified archeologist; All <br /> <br /> <br />cultural resources located by the survey will be evaluated for the National <br /> <br /> <br />Register of Historic Places and treated in accordance with 36 CFR 800. <br /> <br /> <br />Protection of Historic and Cultural Properties. If any cultural resourceS are <br /> <br /> <br />discovered during construction, all activity in the vicinity of the resources <br /> <br /> <br />will stop and the District Archaeologist will be contacted. Appropriate <br /> <br /> <br />measures will then be taken to mitigate any adverse impacts upon these <br /> <br />resources. <br /> <br />XI. Conclusions. <br /> <br />1. The results of this reconnaissance study demonstrate the technical and <br /> <br /> <br />economic feasibility for the addition of a small hydropower facility to the <br /> <br /> <br />existing outlet works of John Martin Dam. <br /> <br />2. As demonstrated. the project produces sufficient benefits, on the <br /> <br /> <br />basis of current trends toward higher future power values,.to justify a plant <br /> <br /> <br />capacity of about 2.5 megawatts. <br /> <br />-' <br /> <br />3. Confirmation of the results of this analysis should be pursued through <br /> <br /> <br />a detailed feasibility study. The feasibility should expand each of the <br /> <br /> <br />issues introduced in this report. Particular attention should be given to <br /> <br /> <br />equipment selection and cost estimation. Power generation calculations ShOUld] <br /> <br /> <br />be based on a sequential analysis of historic flow and reservoir storage data. <br /> <br />18 <br />
