Therefore, all recorded monitoring events are considered Baseline. The monitoring point for S -14 is located on a fork of the Stevens Draw road just above Pond 1. Spring seeps from the east bank of drainage along about 100'sections. (Hanna, 1995) Baseline Information Collection initiated on 9/27/95 and not yet considered complete. Point S -14 has not been influenced by mining. Figure No. 39
