and flagging. Flow was measured with a Teledyne-Gurley Model 625
Pygmy type current meter using the USGS six-tenths-depth method.
During 1985 at the Purgatoire River stations, staff gages were
established on bridges above, between and below the two mines
providing data to calculate a stage-discharge curve for future
discharge measurements. At the mine discharge stations, discharge was
measured by the pump ratings or by a direct volumetric measurement
with a calibrated container. When in operation, calibrated flume
stations utilize Stevens Type F continuous recorders. During each
visit to the flume stations, the recorders are visually inspected and
maintained. When in operation, the following maintenance schedule is
maintained:
1. Checking to see that the clock mechanism was functioning
properly and marking the recorder charts with data
points;
2 . Comparing the staff gage reading and recorder stage
height to verify proper functioning of the stage record-
er;
3 . Removing the chart from the recorder indicating the
station, date, time, stage height, and initials of the
person servicing the recorder; and
4 . Back-flushing and inlet pipe to prevent sediment build-up
and clogging.
2 . 2 Ground Water
Ground water data was collected quarterly at each of the eight
(8) designated stations PAW-1, PAW-2, PAW-3 , PAW-4 , PAW-5, PAW-6,
PAW-7, and CCAW-1. Data was also collected monthly at PAW-7 . The
Purgatoire alluvial wells PAW-1, PAW-2 , PAW-5 and PAW-6 have been in
place for a number of years. Stations CCAW-1 and ACAW-1 were
completed during April 1984 while PAW-3 and PAW-4 were completed in
