INTRODUCTION 



This study was initiated to provide the State of Montana with baseline 

 aquatic resource data on German Gulch Creek and to provide recommended minimum 

 instream flow to protect this resource. The study was funded by the Montoro 

 Gold Company via the Montana Department of State Lands utilizing funds 

 collected under MEPA. 



German Gulch Creek is a tributary of Silver Bow Creek, which in turn 

 flows into the Clark Fork River. This study was initiated in response to a 

 proposed surface mine, ore processing plant, and tailings disposal facility in 

 the German Gulch drainage by the Montoro Gold Company of Reno, Nevada. 



Information provided in this report includes quantification of fish 

 populations, quantification of instream flows necessary for maintaining the 

 existing fishery resource, and baseline water quality, periphyton and 

 macroinvertebrate data.
