• collected during 2000. Well SM-9 was undernned by Panel C during 1993 but showed no appazent
impacts in the field data collected during 2000. No anomalous water quality observations were
apparent during 2000 at the Steven's Gulch shallow groundwater monitoring wells.
Surface Water Monitoring Stations -SPRINGS
East Roatcap Creek -Two springs were monitored in the East Roatcap Creek drainage (refer to
Table 1 and Map No. 4-1) during 2000. Spring 30 had measurable flow in April and June. Water
quality pazameters taken in June were slightly elevated, probably due to low flow conditions. Spring
30 was first undernined in Apri1,1983. Spring 10-]0 had no measurable flow in April, June,
September and December, therefore, no water quality pazameters were taken. Spring 10-10 was
encompassed by the angle-of--draw of Panel Y during October, 1993. Subsidence impacts were not
apparent at either of these locations during 2000.
West Roarcap Creek -Four springs were monitored hi the West Roatcap Creek drainage (refer to
Table 1 and Map No. 4-1) during 2000. Spring 31 was monitored on a montlily basis and exhibited
flows throughout the yeaz with the flow tapering off in the fall. Water quality pazameters were
consistent with ranges previously established for this site. No mining occurred within the watershed
for this spring in 2000 and no mining impacts were evident. Spring 32 was monitored monthly.
Spring 32 exhibited flow throughout the year with the flow tapering off in the fall and winter. Water
quality parameters were consistent with last year's sampling. Spring 10-13 was monitored quarterly.
Flows, as a result of a seemingly dry yeaz, were reduced or non-existant and field parameters
observed at this site were consistent with baseline values. No mining occurred during 2000 in the
• Spring 10-13 watershed. Spring 14-4 was monitored quarterly. Flows and field parameters
observed at this site were consistent with previous values. No mining occurred during 2000 in the
Spring 14-4 watershed.
Steven 's Gulch -One spring was monitored within the Steven's Gulch drainage (refer to Table 1 and
Map No. 4-I) in 2000. Spring 25 lies below an azea of the East mine inactive since 1982. This site
had no measurable flows in April, June, September and December and field pazametezs were
consistent with prior measurements. Spring 25 has been identified as an adjudicated water right
within the permit area.
Two springs with ponds in the. Stevens Gulch drainage, Spring and Pond 13-5, Spring and Pond 13-6
were monitored quarterly in 2000. Spring and Pond 13-5 was undermined during the last half of
1992. Spring and Pond 13-6 was undermined during the end of 1988. Spring 13-5 had no
measurable flow throughout the year and Spring and Pond 13-6 had a measurable flow only in June.
Terror Creek -Seven springs or springs with ponds are found within the Terror Creek drainage
(refer to Table 1 and Map No. 4-1) were monitored during 2000. Spring and Pond 17 is outside the
anticipated extent of mining activity. Spring and Pond 20 and Spring and Pond 7-1 were
undermined during the East Pod development, panels EP-3 and EP-4. All four springs have
extensive data collected to characterize the typical hydrology at these sites. However, these
locations were identified and targeted by the Division as adjudicated water rights within the permit
area. No adverse mine related impacts or other irregularities were noted at any ofthese Terror Creek
. Springs.
