sites, no plots of TSS versus time nor flow versus TSS are <br />presented. <br />5.2 CONDQCTIVITY <br />Conductivity of water for site S1 has been fairly steady in <br />1992 and 1993 (Figure C-12). <br />The conductivity versus time plot for site NPDES 001 shows an <br />overall increasing trend in 1993. Conductivities typically are <br />lower during spring due to increased runoff and rise rapidly after <br />the spring melt (Figure C-13). The flow versus conductivity plot <br />for NPDES site 001 shows the above relationship between the flow <br />and conductivity (Figure C-14). No long-term trend seems to be <br />occurring in Johnson Gulch (001) runoff water quality. <br />Figure C-15 presents conductivity concentrations versus time <br />for NPDES site 002. As seen in previous years, there is a decrease <br />in conductivity in spring due to increased runoff, and then <br />conductivity rises sharply when the flow decreases. Figure C-16 <br />shows a good inverse relationship between flow and conductivity for <br />this site. <br />The conductivity values for NPDES site 006 for 1993 range from <br />725 to 1950 µmhos/cm (Figure C-17). Conductivity values indicate <br />a rising trend from March through June as would be expected. Flow <br />versus conductivity for site 006 is presented in Figure C-18 but <br />does not show good correlation. <br />NPDES sites 008 and 010 discharged three times in 1993. The <br />conductivities for site 008 were 210, 542, and 1620 µmhos/cm at • <br />5-2 <br />
