defined the start of the growing season as the beginning of the first week that average stream temperatures exceeded and remained above 58C for the season; the end of the growing season was defined as the last day of the first week that average stream temperature dropped below 48C. These criteria were based on previous work indicating that adult native cutthroat trout in Colorado spawn when stream temperatures reach 5–88C (USFWS 1998), and that growth typically occurs in trout at water temperatures of approximately 48C and above (Piper et al. 1982).

"Streams that provide 800–900 degree-days probably sustain recruitment in some years, and those with less than 800 degree-days are generally unsuitable for translocations because of a greater risk of recruitment failure and the smaller sizes attained by fry by the onset of winter."

consider putting temp references for spawning from here into the background. We currrently have 7- 11 for spawn triggering in the background but I beliave they mention 5 in the paper above
