Info

April to August, NMFS believes that estimating incidental take during May to July period is representative of the entire April to August period because May to July encompasses the peak and the majority of the C. shasta disease risks for coho salmon fry and juveniles. As discussed in the Effects to Individuals section (i.e., section 12.4), NMFS concluded that the proposed action will likely result in disease risks to coho salmon fry and juveniles that are lower than under the observed POR conditions. NMFS does not have information to specifically estimate what the reduced C. shasta infection rates for salmon will be under the proposed action; however, for the reasons described in the Effects to Individuals section, NMFS concludes that the incidental take of coho salmon fry and juveniles will not exceed the rates observed in the POR. By using the highest percentage of C. shasta infection rates for Chinook salmon observed in the POR, NMFS has a secondary surrogate in addition to the March to August minimum daily average IGD flows and the EWA volumes to estimate the incidental take of coho from the increased disease risk. If the percent of C. shasta infections for Chinook salmon juveniles in the mainstem Klamath River between Shasta River and Trinity River during May to July exceed these levels (i.e., 54 percent infection via histology or 49 percent infection via QPCR), reinitiation of formal consultation will be necessary. 13.2.1.2 Restoration Activities Over the 10-year term of the proposed action, NMFS expects the restoration activities funded under the proposed action will result in incidental take of SONCC ESU coho salmon juveniles. Juvenile coho salmon will be captured, harmed, injured, or killed from the dewatering, structural placement, and fish relocating activities at the restoration project sites. Based on monitoring data of similar restoration activities, NMFS expects no more than 17 juvenile SONCC ESU coho salmon will be captured annually, of which up to 1 may be injured or killed annually. In addition, no more than one coho salmon juvenile may be annually killed by dewatering and no more than one coho salmon juvenile may be annually killed by structural placement. 13.2.1.3 Incidental Take Summary for Coho Salmon A summary of maximum amount or extent of incidental take by life history stage, stressor, and general location within the action area that is expected to occur as a result of the proposed action is presented below (Table 13.6). 391
Cause of Incidental Take Habitat Reduction Elevated water temperature DO reduction Decreased outmigration rates Increased disease risks (C. shasta) Fish relocation Dewatering Structural placement Table 13.6 Summary of annual incidental take of SONCC coho salmon expected to occur as a result of the proposed action.

Measured by a surrogate of the minimum average daily flows at IGD during March to August (Table 13.4) and the expected EWA volumes relative to UKL supply (Table 13.5). In addition, measured by a surrogate of up to 54 percent (via histology or 49 percent via QPCR) of the total annual Chinook salmon juveniles in the mainstem Klamath River between the Shasta River and the Trinity River may be infected with C. shasta during the months of May to July. Up to 17 coho salmon juveniles may be captured each year, of which up to 1 may be wounded or killed each year. Up to 1 coho salmon juvenile may be killed each year. Up to 1 coho salmon juvenile may be killed each year. 392
