1 <br /> <br />Water Quality Analyses and Sampling Frequency <br />The samples are analyzed for the parameters listed in the permit on page <br />4.6-142a. Sampling frequency at the various sites is also listed on page <br />4.6-142a of the permit. Field parameters including pH, temperature and <br />electrical conductivity are measured using a Horiba water quality test <br />instrument. <br />III. Surface Water <br />' Gauging Stations <br />Figure 1 shows the streamflow record for Trout Creek. The graph showing <br />the results of the gauging station along Trout Creek indicates that the <br />monitoring program is being placed on-line early enough in the year to record <br />flows prior to the peak runoff period for each year, The graph shows the <br />monthly average flows and gives some indication of the differences between <br />' mild winters (winters of less snow accumulation) and harsh winters. The <br />streamflow records on Trout Creek for 1984 and 1985 were lost due to a flood <br />caused by an unusually rapid snowmelt during the spring of 1984. It was not <br />until late summer of 1985 that the Trout Creek stream channel stabilized <br />sufficiently to enable the re-installation of the gauging station. Although <br />the magnitude of the 1984 flood was not able to be recorded in terms of flow, <br />anomalies in the water chemistry are noted and will be discussed. The flow <br />record for 1989 shows the peak flow to have occurred in June as previous <br />years, except for 1987 when the peak flow occurred in May. The early peak <br />' flow in 1987 was probably due to a milder winter with the on-set of warmer <br />temperatures occurring earlier in the spring than normal. Flow measurements <br />corresponding to sampling dates are provided at the end of the appendix. <br />' Instantaneous flow records for TR-b are provided in the appendix. Flow <br />records for this location began in 1989. Prior to this time, the flooding <br />which occurred during 1989 caused continual instabilities in the stream <br />channel at this location for several subsequent years. As a result, <br />reestablishing a monitoring station was not possible. In 1988, a new stable <br />reach of the stream channel was located and a monitoring station was <br /> <br />
