(Abstr.) MANAGEMENT
The temperature change that occurs between two
points on a stream is directly proportional to ,%
the surface area of the stream and the heat
load applied between these points. It is
inversely proportional to the flow. Good
estimates of the heat load can be made with
solar radiation data if the stream is uniformly
exposed to sunlight. Foresters can use this
technique to predict the effect of clear-
cutting on stream temperature.

In the past, management of the areas' forested
watersheds has focused primarily upon the
production of timber. Many of the streams in
these watersheds are also the spawning and
rearing sites for a valuable anadromous fishery
and, in many instances, the source of water for
Northwest municipalities. Management of these
watersheds is indeed in a state of transition.
Recent research findings have shown that clearcut
logging can significantly affect stream tempera-
ture, and sediment and dissolved oxygen concen-
tration. Water quality standards prescribed
for interstate waters-are being extended to
small, forested streams.
