DESCRIPTION OF RESEARCH PERFORMED
Rationale for the Study
Domestic sewage effluent into a high mountain valley stream can produce
a complexity of effects on the receiving waters.     Mountain streams are cold
waters that have evolved a highly diverse system which is adapted to a cold
temperature,   clear water environment,  and in which effluents can persist
for relatively long periods of time.     The lower Logan River below the City
of Logan is  such a stream.    It receives domestic effluent from the City
of Logan which at the start of this  study went directly,   untreated,   into the
Logan River and which during the course of the study was diverted through
