• April 13, 1991 <br />Page 6 <br />are presented on Tables 109 and 110. Plots of the flow rate and <br />conductivity data are presented on Fiqures 28 through 31. A <br />summary of the flow rate data for the four surface water stations <br />are presented on Tables 52 through 55. Summaries of the of the <br />water quality data are presented on Tables 56 through 67. <br />The data indicates that the flow rates and water quality are <br />directly related to runoff and evaporation. Half of the ponds and <br />springs had no measurable discharge in 1989 and 1990. In addition <br />the discharge measured in Roatcap Creek was very low. The stream <br />stations showed typical seasonal variability: the flow rate <br />decreased and the conductivity increased each summer. Also, for <br />• those sites with ponds that were not discharging the field <br />conductivity increased during the summer as the pond evaporated. <br />No impacts from mining were observed. <br /> <br />
