sighting all season. Her behavior indicated to us that she was 

 not maintaining a nest or brood. In 1989 we observed broods on 

 Trout Creek but could not locate any in 1990. We suspect the 

 female we observed is either a non-breeding female or a hen that 

 experienced nest loss. 



Trout Creek is similar to other lower Clark Fork tributaries 

 in that it is a highly braided stream with medium shrub and 

 timber cover. We noted areas of medium beaver activity, gravel 

 bars, undercut banks, and stream side meadows. Trout Creek is a 

 very diverse stream with numerous types of streamside habitats. 



Discussion of Potential Harlequin Duck Streams 



Several streams we surveyed stand out as potential harlequin 

 duck streams, due to quality habitat or combination of key 

 components. Our lack of observations on these streams does not 

 indicate that ducks are not there, rather, only that we did not 

 observe any. Survey time was limited and additional surveys are 

 highly recommended. A summary by ranger district of those 

 streams we feel that have quality harlequin habitat follows. 

 Potential harlequin duck streams are highlighted. 



Kootenai National Forest 



Three Rivers District - We feel there is a high probability 

 that breeding harlequins occupy portions of the Yaak River. 

 During recent years, landowners and recreationist have sighted 

 harlequin ducks during spring and summer. Repeated sightings
