State Reg. • salinity. This would make it unprofitable for a rancher to establish a hay field for example. It should be noted that present gross species have adopted to the high salinity concentrations. Regionally, examination of surface water rights, Table 7-41, indicate that surface water rights for irrigation purposes ore south of the permit. ii. Water Availability - Subirrigation Vegetation, shallow groundwater levels, and infra-red photographs indi- cate that subirrigation does occur in the three areas delineated in the "Geomorphic Characteristic" section of this study. Species such as Carex, Poa, Phleum pretense, Agrostis albs, Agropyron smithii, Dactylic glomerate, and Eleocharis spp. indicate available water through subirri- gation or runoff. Shallow groundwater wells have high water levels showing potential for subirrigation. Finally, infra-red photography taken late in the summer show water availability via subirrigation. • iii. Geomorphic Characteristics Reconnaissance of the Seneca II Mine ores indicate three areas which contain alluvial material. These are shown in Exhibit 7-2. All three consist of valley fill material with no terraces. The largest of the three lies in the northern portion of the permit just west of the shop areas. At the confluence of Little Grassy and Grassy Creek, this area consists of approximately 45 acres with alluvial material approximately 40 feet deep. Wells drilled in this alluvium are numbered GW-531, GW-532, GW-533, GW-534, and GW-S6-A. The second area lies along a narrow strip on Little Grassy Creek. Ap- proximately 40 acres in size, this portion of the drainage area contains up to 57 feet of alluvial material. This was determined by the drilling of GW-S32. • The final valley fill area lies in the southern portion of the permit area. In this area, which consists of approximately 10 acres, there is no well 7-7-5 Revised 5/27/81
