<br />. <br /> <br />. <br /> <br />. <br /> <br />, <br /> <br />4 <br /> <br />Brown pelican (Pelecanus occidentalisJ No effect. The Service concurs; an accidental <br />occurrence may occur from storm driven individuals making landfall on the project, but <br />no habitat exists for this species on NIIP lands or the surrounding area. <br /> <br />Mexican spotted owl (Strix occidentalis lucidal No effect. The Service concurs; no <br />habitat exists for this species in the area. <br /> <br />Mountain plover ICharadrius montanus) No effect. The Service concurs. The plover <br />may be a rare visitor to the general area, but it would be very infrequent. <br /> <br />Southwestern willow flvcatcher (Empidonax trail/ii extimusJ May affect, not likely to <br />adversely affect. The Service concurs. Although there is no habitat for this species <br />found on project lands, the reoperation of Navajo Dam to mimic a more natural <br />hydrograph, included as a feature of the proposed project, will contribute to the <br />potential for use of the San Juan River's corridor by the endangered flycatcher. The <br />one nesting area found in proximity to NIIP receives a water supply from irrigation <br />return flow from the Hogback Irrigation Project and would not be affected by the <br />agricultural program at NIIP. <br /> <br />Knowlton cactus (Pediocactus knowltoniiJ No effect. The Service concurs; the species <br />has not been found on project lands. <br /> <br />Mancos milkvetch (Astragalus humillimus) No effect. The Service concurs, the species <br />has not been found on project lands. <br /> <br />Mesa Verde cactus (Sclerocactus mesae-verdaeJ No effect. The Service concurs, the <br />species has not been found on project lands. <br /> <br />Colorado pikeminnow and razorback sucker. May affect, not likely to adversely affect. <br />The Service concurs, based on the following components of the proposed action, the <br />capability of the river to achieve the flows recommended for the endangered fish <br />species over and above the depletions caused by the proposed action, and on the <br />commitments made by the Bureau of Indian Affairs and the Navajo Nation to the San <br />Juan River Recovery Implementation Program. <br /> <br />Reoperation of Navajo Dam to mimic a natural hydrograph of the San Juan River <br />and to meet the flow recommendations for recovery of the endangered Colorado <br />pikeminnow and razorback sucker. The information presented in the Biological <br />Assessment reflects the findings of the San Juan River Recovery Implementation <br />Program's Flow Recommendations Report (1999)-that the depletion of water <br />from the San Juan River necessary to support the proposed project would still <br />allow the flow recommendations formulated for the recovery of the two <br />endangered fish species to be met through the reoperation of Navajo Dam. <br /> <br />Removal of two Navajo-owned diversion dams currently impeding fish movement <br />in the San Juan River and barring Colorado pikeminnow from accessing upstream <br />
