Question 1 1 : With regard to the potential endangered species listing of the Kootenai River 

 Sturgeon in North Idaho, what are the revenue impacts of providing varying 

 flows for the sturgeon Specifically, what would the revenue impact be on 

 BPA for providing a 20, 25, 30, and 35,000 cubic feet per second flow for the 

 sturgeon'' 



Answer: Providing flows for sturgeon in the Kootenai River will have direct revenue 



impacts to BPA as well as to other regional parties which could result in 

 additional indirect revenue implications for BPA. The flows being requested 

 will result in a devaluation or loss of generation power at Libby and 

 downstreams, and will necessitate power acquisitions to replace lost firm 

 power. Lake Kookanusa, behind Libby Dam, will not refill to the extent 

 occurring in current operations resulting in head loss (reduced generating 

 capability per unit of water) through the summer and fall and adversely impact 

 recreation and resident fish 



The following table quantifies a range of costs to BPA associated with the 

 varying flow levels requested:

The Kootenai River downstream fi-om Libby Dam passes through British 

 Columbia, Canada where it joins with the Columbia River. On its way, it 

 passes through several hydro projects owned by Canadian parties the power
