West Elk Mine 2007 Annual Hydrology Report 19 <br />0 3.2.1 Springs above the F-Seam in the North Fork Drainage Basin <br />3.2.1.1 Springy <br />Spring 24-3 is located in the West Flatiron drainage that is the first tributary entering Raven Gulch <br />from the west, which is tributary to the North Fork of the Gunnison and east of the West Flatiron <br />mining panels. This spring issues from a sandstone bed above the F-Seam, flows seasonally, and is <br />typically dry in the late summer and fall months (Map 2). Monitoring at this spring began in 1998. <br />3.2.1.2 Springs E-13-1. E-13-2, E-13-3. E-13-4 <br />Springs E-13-1, E-13-2, E-13-3, and E-13-4 are located in the lower West Flatiron drainage that is <br />the first tributary entering Raven Gulch from the west, which is tributary to the North Fork and east <br />of the West Flatiron mining panels. These springs issue from sandstone beds above the F-Seam, <br />flow seasonally, and are typically dry in the late summer and fall months (Map 2). These springs <br />have been monitored since 2001. <br />3.2.1.3 Spring 26-1 <br />• Spring 26-1 is located in a drainage on the west side of the Deep Creek drainage between the <br />Upper and Lower Deep Creek monitoring stations (Map 2). Deep Creek is tributary to Raven <br />Gulch and the North Fork. This spring is located above the east side of mine Panel 15 (Box <br />Canyon mine panel area) and issues from a sandstone bed above the F-Seam. This spring has <br />perennial flow, but shows strong seasonal variations with high flows in the spring months. <br />Monitoring at this spring began in 1996. <br />3.2.1.4 Seep E14-1 <br />Seep E14-1 is located in upper Box Canyon which is tributary to the North Fork. It is located <br />above the Box Canyon panel area (Map 2). This seep issues from a sandstone bed above the E- <br />Seam and has not flowed through the period of record. It is damp only during very wet spring <br />months, but is typically dry. Monitoring at this seep began in 1998. This spring was permanently <br />covered by well pad construction in WY 2006 and will no longer be monitored. <br />• <br />June 2008 HydroGeo, Inc.
