Appendix E, all native springs have a WSPG prefix (e.g., Spring 5-45 = WSPG45) while all spoil springs have a WSSPG prefix. Spring S-1 is located in an ephemeral stream channel that is the northern tributary to Sage Creek. Further downstream in this drainage is the 009 Pond that was constructed in October 1991. The EC plot indicates a recently decreasing trend. Spring 5-23 is located at the headwaters of the 006 Gulch, in an ephemeral stream channel. This spring is upstream of mining and should not be affected by mining. The EC plot indicated a stable trend. Spring S-41 is located downstream of Spring 5-23 in the 006 Gulch stream channel. It was located just downstream of the silted-in Temple Pond #2. This spring was buried in spoils in 1998. Spring 5-45 (a.k.a., the Olson Spring) is not a flowing spring, but a • three-foot diameter well placed in the alluvium of Dry Creek. Since a well was drilled on the Olson ranch in September 1 980, this "spring" has not been put to use, although it is water-righted for stock use. The EC plot indicates a dec reasing trend. Spring 5-46 is a developed spring first monitoring during the 1979 spring survey. This spring became part of the required monitoring program in 2000. It is located immediately below the 005 Pond. The EC plot indicates an increasing trend. Spring 5-47 was first discovered by SCC personal in 1989 and was monitored first in June 1990. It is a developed spring existing alongside the mine entrance haul road just to the west of the Seneca II- W Meteorological Station. This spring became part of the required monitoring program in 2000. Its EC plot indicates a decreasing trend. Spring S-4S, a.k.a. the Flanders Spring, is located just upstream of the . 009 Pond. This spring became part of the required monitoring program in 2000. The EC plot indicates a increasing trend. 19
