LJ • Hymnlogie MautoiingAnrvides mile upstream o[ the mine site. Because the USGS gauging stations are heated, they were una(iected by freezing temperatures. Data for the 1991 water year [or these sites are presented in Appendtx B and Appendix C, respectively. the resources. Some of the USFS water resources are springs. No changes in the USFS Water Re- sources Map are necessary for. 1991 becatue no new rights were filed for or new uses made in 1991 in the lease area. Seasotal (three times per year) water samples were taken at all sur[ace water monitoring stations except the USGS North Fork station. Measured parameters included pH, conductivity, temperature, total dissolved solids, total suspended solids, total iron, and total manganese. Sampling results are summarized in Appendix D. Minimum and maxi- mum information Cor the bazeline monitoring period is compared with water year 1991 data for the Sylvester Gulch and North Fork Upper sta- tions in Appendix B. Spring Water Monitoring Seven springs were monitored during the 1991 water year (Table 2). Their loptions are shown on Exhibit I. All known springs in the lease area are shown on Map 36 in Volume 5 of the M and R Plan. In accordance with U.S. Forest Service (USE'S) stipulations, a map of USFS water resources haz been included az Exhibit IV. Table 3 summarizes Seasonal measurements (three times per year) of pH, conductivity, temperature, total dissolved solids, total suspended solids, total iron, and total manganese were taken at each of the seven springs. Measured flows, field parameters, and the results of laboratory analyses are presented in Appendu F. Maximum and minimum comparisons are presented in Appendix E. Bar graphs depicting spring flows from 1979 to the present have been included az Appendix G. Of the seven springs, only springs G-14, G-16, G-20, and G-24 were sampled during 1991. Flows at the other three springs were either nonexistent or insufficient for sampling during all three sam- pling periods. Consequently, water quality data are available only for springs G-14, G-16, G-20, and G-24. Groundwater Monitoring 7Wenty-three wells were monitored during the 1991 water year (Table 4).
