<br />Harmonic-mean temperature, amplitude, and the phase angle for 20 stations were <br />est imated by regression ana lys is. Harmoni c-mean temperature (RM) and amp 1 i- <br />tude (A) were found to be re 1 ated to average bas in e 1 evat i on (x) by the <br />equations: HM = 22.8-(0.0018xx) and A = 18.0-(0.0011xx). Water temperature <br />also was found to be directly related to air temperature. Suspended- <br />sediment discharge in the basin ranges from 0.24 ton per day at a discharge of <br />90 cubic feet per second in the South Fork White River at Buford to 130,000 <br />tons per day at a discharge of 1,150 cubic feet per second in the White River <br />upstream from Rangely. Seven chemical constituents (alkalinity, calcium, <br />chloride, magnesium, potassium, sodium, and sulfate) at five stations on the <br />Whi te Ri ver were regressed agai nst di scharge and specifi c conductance. The <br />standard errors of estimate ranged from 6.3 to 95.1 percent. Benthic inverte- <br />brates sampled at six stations indicate that the upstream reaches of the White <br />River are not polluted. <br /> <br />3 <br />
