Therefore, all recorded <br />monitoring events are considered Baseline. <br />The D32-4 Monitoring Point is on upper Terror Creek. It is located at the Cottonwood Stomp ford. This point is used to obtain <br />conductivity, pH and temperature readings. The irregular stream channel found at this location does not provide an adequate <br />method of determining flow values. Flow values are taken from the USGS discharge information for station #09132985. <br />Station #09132985 is operated seasonally, March through October only. <br />Baseline Information Collection initiated on 10/31/97 and not yet considered complete. <br />Point D32-4 has not been influenced by mining. <br />Figure No. 94
