sites; 2) it was present in all sections below Nevada Creek; and 

 3) it was known to be desirable rearing habitat. Riffle areas 

 with rock border, however, provide a better comparison of rainbow 

 trout YOY densities than brown trout YOY. Brown trout YOY appear 

 to prefer root/brush borders over rock borders (Spoon 1987). 

 Above Nevada Creek the rock borders were not generally available 

 and sampling was confined more to the root/brush borders. 



We used a Coffelt Model BP-IC gas-powered backpack 

 electrof ishing unit; 50 to 150 watts were required to capture 

 fish. All observed as well as captured YOY were used to 

 calculate catch per unit effort. Sections were measured with a 

 tape to determine length of shoreline sampled. Recruitment 

 potential of selected tributaries was also determined using this 

 YOY sampling method. 



WATER TEMPERATURE 



Water temperature recorders were installed at Raymond 

 Bridge, Scotty Brown Bridge, and at the inactive USGS station 

 above Belmont Creek. We used 30-day chart recorders manufactured 

 by Partlow and Taylor. Thermographs were calibrated with 

 laboratory thermometers at the time of installation and several 

 times after installation. Recorders were operated from 

 approximately mid July through September, 1988. 



CREEL CENSUS 



A voluntary creel census was initiated in July to gather 

 catch information. Incidental fisherman contacts during field 

 activities were made and mail-in cards handed to these fisherman. 

 We also used one weekend day per week to contact fisherman and 

 hand-out creel census cards. Cards were also given to game 

 wardens and selected businesses making fisherman contacts in the 

 area. 



BULL TROUT REDD SURVEY 



Bull trout redd counts were made in the North Fork of the 

 Blackfoot and Monture Creek by walking known spawning areas at or 

 near completion of the spawning period.
