Wounded Buck to 125 on Swift Creek. Temperatures ranged from 9 

 degrees C on Swift Creek to 17 degrees C on Sullivan Creek. 

 Gradients were all under .02 feet rise/feet run. Vegetation was 

 all medium to high shrub or trees except Sullivan Creek which had 

 low density shrub and trees because the creek flowed mostly 

 through a wide, barren, gravel streambed. Channel types were 

 braided or canyon type channels. All creeks had medium to high 

 numbers of loafing sites. Harleguin duck distribution on the 

 Flathead Forest is probably limited by factors other than these 

 stream characteristics. Bengston (1971) and Kuchel (1977) both 

 suggest that breeding success may be limited by invertebrate 

 numbers. I believe that factors beyond those measured on this 

 survey, such as stream productivity and stability, may determine 

 which streams harleguins occupy since streams in this survey 

 found to have harleguins possessed the same characteristics 

 measured as many streams that harleguins were not found on. 



SUMMARY OF HARLEQUIN DUCK STATUS BY RANGER DISTRICT 



Tally Lake Ranger District 



Most of the streams evaluated on the Tally Lake Ranger 

 District were small, low gradient streams that were slow and 

 swampy compared to the habitat criteria I used. Good Creek and 

 Logan Creek contained areas that appeared to offer potentially 

 suitable habitat, but no ducks were found. The upper Stillwater 

 River appeared to be guite suitable, especially the area near the
