  • TEMPERATURE:


Temparature --- FISH RELATED

  • Twelve degrees Celsius (54 F) is the minimum for HBC growth and 16 degrees Celsius/ 61 F, is optimal. (NPS CFMP-EA_ pg 78)
  • Volume not fluctuations is the strongest factor in downstream temperatures.
  • For every 1 degree increase in temperature, predation vulnerability of HBC is decreased by about 5% (130220_AMWG Minutes)

Temparature --- DAM RELATED

  • Warmest Glen Canyon dam release temperatures occur July- November.(RValdez)

TBD

  • LCR: Warmest downstream temeratures (RM 62) and Middle Granite Gorge (RM 127)occur July-October, because of cooler fall temperatures and low sun angle.(RValdez)
  • LAKE POWELL: Warmest surface temperature is July through August.

TBD
