Occurrence of whirling disease of trout in western United States
Whirling disease of trout, caused by Myxosoma cerebralis, was diagnosed in 1966 for the first time in rainbow trout (Salmo gairdneri) from California and Nevada hatcheries. In 1969 the first incidence of this disease in cutthroat trout (S. clarki) was reported in Nevada. To date these have been the only confirmed cases of whirling disease in western United States.

Mass movement of black fly larvae on silken threads (Diptera: Simuliidae)
Stoppage of waterflow in a stream resulted in the migration of massive numbers of black fly larvae on silken threads. Larvae were found on single silken threads, but the heaviest concentrations were on “cables” composed of 25-50 individual silken threads. The larvae were attached in concentric rings around the silken threads and cables.
