| Abstract/Description or Keywords |
This report summarizes results of the 2005 kokanee escapement survey conducted in Koocanusa Reservoir and its associated tributaries. Aerial counts were conducted on 3 and 5 October 2005. An estimated 115,760 spawning kokanee were enumerated in 11 index streams and rivers in the Koocanusa Reservoir drainage during the fall of 2005. The 2005 kokanee escapement index was 27% higher than the 2004 index, however, it was the second lowest recorded since 1996. It is recommended that kokanee escapement be monitored annually as a trend through time indicator of changes in adult kokanee abundance in Koocanusa Reservoir.
