Therefore, all recorded <br />monitoring events are considered Baseline. <br />The location for the D34-14 monitoring point is on Hubbard creek just below the igneous intrusion noted as Iron Point. The <br />can be found where a sapling has been painted white. The point where field parameters were taken did not provide an adE <br />method to determine flow values. A USGS station is now in place (#09132940) <br />Note 1: USGS did not collect flow data duiring first quarter 2015. <br />Baseline Information Collection initiated on 10/31/97 and not yet considered complete. <br />Point D34-14 has not been influenced by mining. <br />Surface Water <br />Figure 66 <br />
