  • 15 mayfly genera, five Plecoptera (stonefly) genera, and three Trichoptera (caddisfly) genera were believed to have been extirpated from the river reach between the dam and Red Creek after the construction of Flaming Gorge Dam (Vinson 2001).
  • Twenty years after the installation of the selective water device, the number of aquatic insect taxa routinely collected upstream of Red Creek was as low as or lower than before partial thermal restoration. Gammarus lacustris was the only taxon that initially appeared to benefit from partial thermal restoration resulting from the addition of the selective water device in 1978.
  • Between 1993 and 1999, the tailwater macroinvertebrate community consisted of amphipods (61%), dipterans (32%), mayflies (4%), and Coleoptera (coleopterans or beetles) (3%).
