<br />001711 <br /> <br />Long Hollow Dam and Reservoir Summary Report-Preliminary Draft <br /> <br />about 160 acres was surveyed for cultural resources, which is based on an LHR maximum pool <br />elevation of 6,31 0 feet (see Fig. 1). <br /> <br />During the survey, five archaeological sites and five isolated finds were encountered and <br />recorded. The five archaeological sites include the remains of a pre- World War I homestead, two <br />ditches and associated features dating from the 1920s through the 1950s, and two prehistoric <br />sites that may represent Archaic Period use. The two prehistoric sites (5LP7399 and 5LP7400) <br />were recommended by LP AC as eligible for nomination to the National Register of Historic <br />Places. The three historic sites (5LP7396, 5LP7397, and 5LP7398) were not recommended by <br />LP AC as eligible for National Register nomination. (Given the number of cultural sites found in <br />the Ridges Basin area. I would be very concerned that additional work in this area may be highly <br />likely and would provide increased contingencies.) <br /> <br />Each prehistoric site contains features or areas with intact cultural deposits within the zone likely <br />to be impacted by LHR construction and development. LP AC recommended that a plan <br />approved by USACE and the Colorado State Historical Preservation Office (SHPO) be <br />implemented to mitigate any adverse impacts. An approved treatment plan for the two sites <br />would ideally include the recovery of data from the impacted portions of the two sites; analysis <br />of any recovered artifacts, botanical samples, fauna samples, dating samples, and other relevant <br />data; and preparation of a report detailing these investigations and their results. LP AC findings <br />were submitted to USACE, which forwarded them to the SHPO. <br /> <br />6.5 Indian Trust Assets <br /> <br />The effect of the project on Indian Trust Assets also will be studied in cooperation with USACE <br />pursuant to appropriate consultations with Native American tribes and nations. This work will <br />be used to determine if any cultural resource issues present a fatal flaw for the project. Potential <br />mitigation needs will also be considered. (Are their any Indian lands involved? We need a land <br />ownership map of the basin attached to the reoort. <br /> <br />991-077.115 <br />May 2004 <br /> <br />Wright Water Engineers, Inc. <br /> <br />Page 12 <br />
