Spring S-1 is located in the channel of an ephemeral drainage that is an unnamed tributary <br />to Sage Creek. Further downstream in this drainage is the 009 Pond that was constructed <br />in October, 1991. This spring was flowing during the June visit, but was dry by August. <br />It displayed a CaMg-HC0 SO <br />type water with a TDS value of 484 mg/l. This value is both <br /> 3 4 <br />lower than the 634 mg/l baseline average and the baseline range of 530 to 838 mg/l. <br />Spring 5.23, located at the head waters of the 006 Gulch, is Located in the channel of an <br />ephemeral drainage. This spring is upstream of proposed mining and should not be affected <br />by mining. <br />Spring 5-41, located downstream of Spring 5.23 along the 006 Gulch, is again located in <br />the channel of an ephemeral drainage. It is situated just downstream of the silted-in <br />Temple Pond #2. It receives water from numerous seeps issuing from [his marshy, silted-in <br />pond. Samples at this site display a Mg-504 type water with en average TDS value of 3,384 <br />mg/L in 1993. The baseline average TD5 is 2,177 mg/t with a baseline range of 930 to <br />3,296 mg/l. <br />Spring S-5, located downstream of Spring 5-41 along a side draw [o the 006 Gulch, is also <br />in an eph emerat channel. The last flow monitored here was in June, 1983, and is the only <br />sample on record. It uas a MgCa-HC03 type water with a TDS of 775 mg/l. <br />Spring 5-46 is a developed spring first monitoring during [he 1979 spring survey. This <br />spring is not part of the required monitoring program, however, due to its strategic <br />location (immediately below the 005 Pond dam), monitoring a[ this spring has been <br />voluntarily re-established in 1992. In 1993, samples at this site displayed e <br />NgCe-504HL03 type water with an average TD5 value of 1,318 mg/l. <br />Spring 5-47 was first discovered by PWCC pe rs onaL in 1989 and was monitored first in June, <br />1990. Ic is~a developed spring existing alongside the mine entrance haul road just to the <br />west of the Seneca It-w Meteorological Station. It is not required by the hydrological <br />monitoring program, monitoring is voluntary. In 1993, samples from this site displayed a <br />NaMgCa-504 type water with an average TDS value of 1,519 mg/l. <br />The hydrology monitoring program a[ the Seneca II-Y Mine requires a spoil spring survey <br />every year after the spring snowpack runoff. No spoil springs have been discovered. <br /> • <br />12 <br />
