fishery potential of Sixmile Creek as fair and noted that the cutthroat 

 trout specimens appeared to be of the west slope variety. 



Fishery data from the Sixmile Creek study section indicate that the 

 stream may be an important rearing area for the California-French Creek 

 drainage. The presence of small numbers of cutthroat leads to the 

 possibility that larger populations may exist in other portions of the 

 stream. Such populations would add to the importance of the fishery of 

 Sixmile Creek. 



4. FLOW RECOMMENDATIONS 



Cross sectional data were collected in a 165 foot riffle-run sequence 

 located approximately at stream mile .5 (T3N, R12W, Sec 25A). Five cross 

 sections were placed within this sequence. The WETP program was calibrated 

 to field data collected at flows of 21.5, 6.6, 3.2 and 1.8 cfs. 



The relationships between wetted perimeter and discharge for a composite 

 of four riffle cross sections is shown in Figure 8. Lower and upper inflection 

 points occur at 2 and 4 cfs. Based on an evaluation of the existing fishery 

 and recreational use potential, a flow of 2.5 cfs is recommended for the low 

 flow period (July 1 - April 30). Due to a lack of long term flow data, 

 recommendations for the high flow period (May 1 - June 30) cannot be derived 

 for Sixmile Creek.
