Proposal for Calculating Cumulative Salvage Index Values Used For Estimating Take Likely to Occur under the USFWS Old and Middle River Flow RPA for Adult Delta Smelt

The objectives of this paper are to provide a rationale why the United States Fish and Wildlife Service (USFWS) Incidental Take Statement should include more years in its calculation of anticipated incidental take of adult delta smelt under the 2008 Biological Opinion with the Reasonable and Prudent Alternative (RPA) action to avoid jeopardy to the species and adverse modification of critical habitat and provide a statistical method by which this can be achieved.
