.~.: .'"' ... '", i.u:'" ,:.: In addition, there is potential for the design of Pueblo West's intake structure to have a long-term impact if it impedes diversions to the West Pueblo Ditch which supplies the swim beach with water. (See Hydrology section for related information.) Changes in the amount of Pueblo West's water usage are not expected to have any impact on Arkansas River white water rafting. Net river flows are expected to remain similar to recent years due to the expected continued cooperative flow management by the State and Reclamation. Construction of the proposed action is planned to occur in off-season months, particularly the winter months when recreational activities are expected to be reduced. However, the bike/pedestrian trail and access road would need to be temporarily closed during construction activities. To mitigate these potential impacts, the following actions will be required: . Construction activities will be conducted in a manner that minimizes disruption of traffic on the access road, including providing at least one lane of through traffic at all times or an alternative route in the immediate vicinity, and shall be coordinated with the Lake Pueblo State Park. · Construction of the pipeline will be conducted in such a manner that the bike/pedestrian trail is closed for the shortest reasonable time frame, and shall be coordinated with the Lake Pueblo State Park. Threatened and Endangered Species Affected Environment This section constitutes Reclamation's Threatened and Endangered Species (T&E) determination under Section 7 of the Endangered Species Act (ESA). Information on the potential for threatened, endangered, and candidate species, and their habitat within the action area of the proposed project were obtained from the U. S. Fish and Wildlife Service (Service), Ecological Services, Colorado Field Office. The action area for this project includes the Arkansas River between Twin Lakes and Pueblo Reservoir, Pueblo Reservoir and the area to be disturbed by construction of the pipeline and related facilities. The Service indicated the potential for twelve federally-listed threatened, endangered, or candidate species to be fou.nd in the vicinity of the project area. Four of these species, the Preble's meadow jumping mouse, Uncompaghre butterfly, penland alpine fen mustard, and the Colorado butterfly plant, are clearly outside of the action area or any potential impacts from the project. Consequently, these four species were not considered in this analysis. The remaining species are listed in Table 3.3. The Colorado Division of Wildlife's species of concern list was reviewed to determine if any of these species may potentially be impacted by the proposed action. No species of concern were identified that may potentially be impacted by the proposed action. 15
