than the Hayden Station data when evaluating the spring runoff observed this year at Seneca II-W. I Ground Water Water Levels. Water levels for all wells that are in the current monitoring program are presented in Appendix C. Hydrographs of all historic data for each well are presented prior to the water level reports (for all data since 1999) for each respective well in the same appendix. By presenting all historic data, trends related to seasonal and annual variability are more clearly evident. Water level measurements are taken with an electrical water level indicator, or in the case of a few shallow alluvial wells, directly from a steel tape. Site information, including sampling frequencies, is presented in Table 3, Summary of Ground Water Monitoring Wells. Ground water level monitoring frequencies are listed in Appendix 15-3a of the Seneca II-W PAP. - Alluvium. The alluvial monitoring We11s WHAL6-1, 6-2, 6-3; 6-4, and 7-2 are located along Hubberson Gulch. All wells exhibit water level seasonal variations typical for the alluvium, i.e., shallow after the spring recharge, deepening towards the fall. Well WHAL10 is located approximately one-half mile downstream of the NPDES 006 pond on a tributary to Hubberson Gulch. It also exhibits seasonal variations typical of previously mentioned monitoring wells. Water levels observed this year for all of these wells fell within their historic ranges. We11 WDAL11, located immediately above the NPDES 005 Pond, is normally dry. Well WSAL12 is located next to the lower Sage Creek flume site (SW- S2W-FG4). Well WSAL13 is located on the northern tributary to Sage Creek below the NPDES 009 Pond. Well WSAL14 is located on the southern tributary to Sage Creek below the NPDES 015 Pond. Most of these wells exhibit typical seasonal variations. Water levels observed this year for most of these wells fell within their historic ranges. Well WSAL12 exhibited the lowest water level on record. 3
