<br />Appendix I <br /> <br />Conductivity, pH and dissolved oxygen meters were received at the end of week 5 so that <br />measurements presented here are for only the remaining two weeks of the study. This is <br />too few data to make any deftnitive estimates and as well, the instruments received were <br />old and most likely unreliable. The Orion Research digital pH meter (model 201) would <br />not perform a two-point (pH 7.0 and 10.0) calibration, and most likely had a battery <br />problem. Conductivity was measured with a YSI Model 33 S-C- T Conductivity Meter. <br />Readings are in pmhos/cm2. Barry Long, who sent the equipment from the NPS Water <br />Resources in Ft. Collins, had trouble with the sensor adjustments prior to sending it. <br />Finally, dissolved oxygen was measured with a YSI Model 57 Oxygen Meter. Of the <br />three instruments, this was probably the most reliable since it was possible to calibrate it <br />accurately with absolute barometric pressure. Readings are in mg/L. <br /> <br />T bl 4 Ab' t' <br /> <br />t Mill d C <br /> <br />a e : 10 IC measuremen s, ar anyon. <br /> SECCHI <br />DATE TIME TEMP@ 5 CM TEMP@122 CM pH ECI D02 DISK <br /> (em) <br />01 MAY 1700 20 19 <br />08 MAY 1800 21 20 <br />15 MAY 1800 22 21 <br />22 MAY 0730 17 17 <br />29 MAY 1255 20 16.5 <br />05 JUN 1330 23 20 7.45 3.5 4.8 24.13 <br />12JUN 1430 23 20 8.75 2.5 1.2 12.00 <br />10 JUL 1115 24 8.20 5.5 0.2 165.00 <br />T readings m nhoslcm2; multi )1\ bl a tactor otll 'tor-sTune and 12 June <br /> <br />\l PY Y <br />2 readings in mgIL on a scale from 0-20,05 and 12 June, and on a scale from 0-5 on 10 Jun <br /> <br />Table 5: Abiotic measurements, Anderson Bottom. <br /> <br /> SECCHI <br />DATE TIME TEMP@ 5 CM TEMP@ 122 CM FLOW pH ECI D02 DISK <br /> oc oc ( efs) (em) <br />01 MAY 0900 17 16 12700 <br />08 MAY 0830 17 16 12700 <br />15 MAY 1045 21 16 22900 <br />22 MAY 1600 21 20 26800 <br />29 MAY 1430 18 17 25800 <br />05 JUN 1510 21.5 19.5 29400 7.45 2.8 4.5 5.5 <br />12 JUN 1310 21.5 20 30300 8.70 2.5 1.8 9.5 <br />I readings m \l nhoSlcm2; mulil ply by a tactor of II <br /> <br />P <br />2 readings in mglL, on a 0-5 scale <br /> <br />16 <br />
