Long Hollow Dam and Reservoir Phase I Summary Report development to occur. The SJRIP is a cooperative effort involving federal, state and local governments, Indian tribes and water users. New depletions for the LHR project are estimated to average 1,470 AF/yr, which exceeds the SJRIP small depletion allowance and may cause jeopardy to the existence of the endangered fish and designated critical habitat. The SJRIP provides the reasonable and prudent alternative to the jeopardy finding and allows projects such as LHR to proceed after certain findings relative to the project are made. Therefore, the U.S. Fish and Wildlife Service (USF&WS) requested that LPWCD have the SJRIP flow model run to determine if LHR depletions will impact the SJRIP flow recommendations for the two endangered fish in the San Juan River. A USBR run of the model determined that LHR project would not impact any of the primary or secondary flow recommendations. This LHR model run by the USBR was reviewed by the SJRIP Hydrology Committee on May 18, 2004. 6.2.4 Summary of Conclusions of T&E Species Evaluation _ Analysis of LHR's potential impacts on T&E and candidate species is summarized in Table 2. As a result of the project's potential to have an adverse impact on San Juan River endangered fishes, Section 7 Consultation with the USF&WS is necessary. The positive results of the LHR model run will be presented to the USF&WS as part of the consultation. In order to minimize potential adverse impacts from LHR on roundtail chub and flannelmouth sucker, LPWCD is working with the CDOW to seek to establish a monitoring and flow mitigation plan that meets the requirements of the Compact, while also meeting seasonal flow requirements for these fish. 6.3 Wetlands USACE is coordinating the LHR 404 permitting process with federal agencies.
