. The Big Blackfoot River restoration progress report for 2002 and 2003 . Fish populations; Fishes; Fishery management; Trout fisheries; Stream ecology; Blackfoot River (Mont. ). Blackfoot River and tributary temperatures Collecting watershed-wide water temperatures is a major element to a habitat assessment and monitoring program (Figure 12). Temperatures studies during 2002 and 2003 involved: 1) baseline and long-term data collections at established sites throughout the Blackfoot watershed; 2) assessing tributary restoration projects; 3) identifying thermal regimes (natural and anthropogenic) favorable and unfavorable for trout; 4) monitoring temperature triggers of the Drought Plan; and 5) relating other biological assessments (movements, spawning, etc.) to thermal properties of the river system. Summaries of temperature data are found throughout this report. All raw and summary data for all monitoring sites are located in Appendix I. Blackfoot River Tributary. During 2002 and 2003, we collected 78 water temperature samples at 59 locations in 38 tributaries, along with 13 samples at seven sites in the Blackfoot River (Appendix I). Figure 13 shows a portion of the river data for critical summer periods between 1997-2003. These data outline the warming (Nevada Creek) and cooling (eg. North Fork) influences of key tributaries and the general summer-time thermal properties of the lower ~70 miles of the Blackfoot River.
