in Gallatin County: Bozeman Creek (18 stations of ca. 100-200 m each, distributed 

 over 6.4 km of stream), Mathew Bird Creek (7 stations) and Figgins Creek (2 

 stations). One stream, Fleshman Creek (3 stations) flows through the city of 

 Livingston (Fig. 2) in Park County. Details of station locations are in Appendix I 



Urban stations did not include the most drastically altered parts of some 

 streams — those parts that had been completely enclosed in culvert for one or 

 more city blocks. It would have been too dangerous to electrofish and perhaps 

 also to do other sampling in these sections. 



Study station lengths ranged from 89 to 201 m, except for one that was 

 300 m long. Seventy-two per cent of stations were between 90 and 100 m long. 



Bozeman (Sourdough) Creek originates at the outlet of Mystic Reservoir 

 (elevation 1950 m) in the north end of the Gallatin Range in southwestern 

 Montana and flows northwest for 26.6 km, dropping 510 m (19.2 m/km) to its 



mouth (elevation 1440 m) at the East Gallatin River below Bozeman. The Bozeman 



2 

 Creek drainage basin covers about 168 km . Average annual precipitation for 



the basin is 6l cm (24 inches). 



Mathew Bird Creek (Spring Creek on the Bozeman topographic quadrangle of 

 1953) is tributary to Bozeman Creek at about stream km 3-5 at elevation 

 1475 m. Elevation of the source is 1585 m. Stream length is about 3.3 km. 



Figgins Creek (Middle Creek Ditch), enters Mathew Bird Creek at stream 

 kilometer 1.6. It originates from Hyalite Creek in T3S,R8E,Sec. 3- 



Fleshman Creek heads in eastern foothills of the Bridger Range in 

 Park County and flows southeast for 14.8 km before discharging into the 

 Yellowstone River in the city of Livingston. Its elevations at origin and 

 mouth are 1707 m and 1372 m, respectively. The average annual precipitation 

 for the Fleshman Creek drainage basin is 40.6 cm (16 inches).
