of river. During the winter of 1978-79, Craighead and Craighead 

 (1979) reported 1 bald eagle was consistently observed using the 

 reservoir and up to 4 birds may have used the area. A range of 

 losses, based on the combination of tlie population estimate (20 

 bald eagles) and the observation of wintering eagles (1-4), was 

 estimated to be 16 to 19 bald eagles. Abundance of injured or dead 

 fish available below the dam may have provided food for additional 

 wintering eagles displaced from the pool area; however, due to the 

 partitioning of the winter habitat observed by Craighead and Craig- 

 head (1979) it is unlikely this displacement occurred. The esti- 

 mate of losses is probably conservative as the inundated reach, 

 particularly the area upstream from the original townsite of Rex- 

 ford, may have been better habitat than the lower reaches (A, 

 Christensen 1983, pers. commun.).
