Two criteria to meet water teDlperatU1'CS at Cameo !liP are sho\\'1l: (1) the DOrJDal water temperature at Cameo as :I fullCtion of lSSIIJtIecl discharge UI4 DomW monthly mete01'olopcal cODClitiOIlS at Umeo pee. and (2) the mean momhly water temperature assoc:iatecl with the Dormal monthly hye1tometeoroloP:al conclitions at Cameo pp (14.01QC in JUDe and 18.1SoC in Jul~'). assumed criterion. are simulated by the temperature versus site disclurge curves at Black. Rocks. A reservoir at Cameo could be managed according to either water temperature criteria. Water resource management projects upstream from Cameo may be better simulated bv the fIrSt criterion (normal 'll."ater temperatures at Cameo) 'because the stream flow.- above Cameo would be subject to othe!'\\ise natural hydrometeorolopcal conditions. The suitable squawflSh and chub spawning temperatures are superimposed on the temperature discharge plot, Clear- ly. the spawning tem.perature requirement for squawf15b at Black Rocks would be met fot' all discharges less than the me~n July flow (:!33 cms) at Black Rocks and for dis- chrges at least up to 350 ems depending upon the ap- plicable water temperature criteria at Cameo. However. the chub spawning temperature could require a Black. Rocks flo\\' r3n~ in June as narrow as :70 to 480 cms depending upon the applicable water temperature criteria at Cameo. The mean June flow is 3:5 ems at Black Rocks. The results of the \"alidation check at the State Line !!3l!e, 'xhich is 10c:1ted 8 kilometers below Black Rocks, was :'O.13uC and -0.180(' for the normal June and July hydro- mett'orulogicaJ conditions. respectively.
