CONCLUSIOr-;

The two examples clearly demonstrate the power oi the
insue:un water temperature modeling capability. The IJlQ.SW
allows !be lL~eT" to ~edict. with reasonable confidence.
downstream temperature impacts of changes in upstream
discharges. water temperatures. and even stream geometry
reprdless of the complexity of the sueam network.
lbis model can be used in numerous applications to
analyze projects pWmed to enhance or suspected to affect
the aquaiic habitat temperature regime. As knowledge of
the temperature requirements of aquatic species expand,
more sophisticated use of this model is expected.
