2016 Recommended Modifications to the West Elk Mine Hydrologic Monitoring Network 32
Note: No baseline field or laboratory water quality data because the site was initially monitored voluntarily (HydroGeo, 2016b)
prior to officially being added to the monitoring network in 2005 (CDRMS, 2006)
Not Detected (ND) values graphed as zero.
2.2 Box Canyon Area Monitoring Network
2.2.1 Box Canyon Area Springs
Seep E-14-1 is the only spring in the Box Canyon area that is recommended for removal from
the monitoring network.
2.2.1.1 Seep E-14-1
Seep E14-1 is located in upper Box Canyon which is tributary to the North Fork of the Gunnison
River. Between 1999 and 2006 this seep was dry or damp. As a result, there are no field or
laboratory water quality data for analysis. This seep was covered by MVB pad construction in
August 2006 and has not been monitored since. The site was reclaimed in 2012 and the seep (a
muddy area) again developed (MCC, 2016).
A time -series flow graph for Seep E-14-1 is shown on Figure 27.
