The area of concern for monitoring point 032-0 has not been affected by the mining opera5on. Therefore, all recorded
monitoring events are considered Baseline.
The 0324 Monirodng Point is on upper Terror Creek. It is located at the Cottonwood Stomp ford. This point is used to obtain
wnductivity, pH and temperature readings. The irregular stream channel found at this location does not provide an adequate
method o/determining flow values. Flow values are taken from the USGS discharge information for stab"on #09132985.
N/A =Not available
Baseline Information Collection inhialed on 10/31/97 and not yet wnsidered complete.
Point 0324 has not been influenced by mining.
