gradient, and availability of midstream loafing sites (0, 1-3, 

 >3/10 m) . Stream flow data for the Boulder River drainage was 

 determined by measurements taken 5 September using the methods of 

 robbins and crawford (1954). seasonal (1990) and historic (1981- 



1990) STREAM FLOW DATA FOR THE BOULDER AND GaLLATIN RIVERS WAS 



provided by the u.s. geological survey (helena, mt) . gauging 

 stations are located on the boulder river at big timber and the 

 Gallatin River at Gallatin Gateway. The Big Timber station does 



NOT provide actual STREAM FLOW FOR THE BOULDER RiVER STUDY AREA 

 BUT SHOULD ACCURATELY REFLECT RELATIVE SEASONAL AND YEARLY 

 CHANGES THAT OCCUR AT THE STUDY SITE. ThE GaLLATIN GATEWAY 

 STATION PROVIDE ACTUAL STREAM FLOW DATA FOR MUCH OF THE GaLLATIN 



River study area. 



RESULTS 



Sections of 14 streams were surveyed in Gallatin and Custer 

 National Forests during May - August 1990 (Figure 2) . These 

 streams represent all the potential harlequin duck breeding 



HABITAT IN GaLLATIN NATIONAL FOREST, BASED ON SIZE AND GRADIENT 

 requirements, a DESCRIPTION OF SURVEY ROUTES IS GIVEN IN TABLE 1.
