The point where geltl parameters are taken does not provide an adequate metlrotl to determine lbw values • Baseline Inrormation Collection initiated on 10rd1/1997 and nol yet considered complete after monitodng for-50 months. Point D3414 has not been influenced by mining. The location far the D34-14 monitoring paint is on Hu66ard Creek just below the igneous intrusion noted as Iron Point. The location can be found where a sapling has been painted white. MDL =Method Determination Limn BIANK=Not Tested Monitoring Point Table 71
