West Elk Mine 2008 Annual Hydrology Report 28 <br />40 3.2.1 Springs above the F-Seam in the North Fork Drainage Basin <br />3.2.1.1 S_prinQ 24-3 <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 />B-seam mining panels. This spring issues from a sandstone bed above the F-Seam, flows <br />seasonally, and is typically dry in the late summer and fall months (Map 2). Monitoring at this <br />spring began in 1998. <br />3.2.1.2 Snrint-s E-13-1, E-13-2, E-13-3, E-13- <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 B-seam mining panels. These springs issue from sandstone beds above the F- <br />seam, flow seasonally, and are typically dry in the late summer and fall months (Map 2). These <br />springs 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 />is 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 B-seam mine panel area) and issues from a sandstone bed above the F-seam. This spring <br />has 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 B-seam panel area (Map 2). This seep issues from a sandstone bed above <br />the E-seam and has not flowed through the period of record. It is damp only during very wet <br />spring months, but is typically dry. Monitoring at this seep began in 1998. This seep was <br />permanently covered by well pad construction in WY 2006 and is no longer being monitored. <br />3.2.1.5 Springy 27-1 <br />Spring 27-1 is located in upper Sylvester Gulch, is tributary to the North Fork of the Gunnison <br />River, (Map 2) and feeds an area known as "twin ponds". This spring issues from alluvial <br />sediments and is located above the south side of mine panel 15 (Box Canyon B-seam mine panel <br />. area). Hydrologic monitoring measurements from this station are taken at the end of a plastic drain <br />pipe. Monitoring at this spring began in 1996. <br />June 2009 HydroGeo, Inc.
