Fina] West Elk Mine 2005 Annual Hydrology Report 10 <br />• sites in Sylvester Gulch: Upper, Middle and Lower Sylvester Gulch, monitor areas up-gradient of <br />the mine surface facilities area, areas down-gradient of the mine water discharge point and mine <br />facilities, and areas down-gradient of the mine spoils dump, respectively. <br />3.1.2 Lower North Fork Drainage Basin Surface Water Monitoring <br />Stations <br />3.1.2.1 North Fork Lower <br />The North Fork Lower station monitors the North Fork down-gradient of the mine facilities area <br />and mine discharge points (Map 2). <br />3.1.2.2 Lower Gribble Gulch <br />Gribble Gulch is an ephemeral stream that flows only in response to storm events and spring <br />runoff. This stream drainage drains the western mine panel area. The Lower Gribble Gulch station <br />is located west of the mine and was established to monitor the effects of mining in the west and <br />northwest mine panel area. <br />3.1.3 Minnesota Creek Drainage Basin Surface Water Monitoring Stations <br />• <br />3.1.3.1 Lick Creek Flume <br />Lick Creek is an ephemeral stream that is tributary to upper Minnesota Creek and flows only in <br />response to storm events and spring mnoff. Lick Creek drains the southern part of the un-mined <br />South of the Divide (SOD) coal lease area (Map 2). This monitoring station was established in <br />1977 when MCC was planning to develop this tract. The site was also established as part of the <br />Minnesota Creek Water Augmentation Plan (WWE, 1986). <br />3.1.3.2 South Prong Creek <br />South Prong Creek is an intermittent stream that is tributary to upper Minnesota Creek. South <br />Prong Creek drains the southernmost part of the un-mined South of the Divide (SOD) coal lease <br />area (Map 2). This monitoring station was monitored during the rising limb and peak flow periods <br />in 2005, and additional monitoring is not planned until mining progresses into the southern portions <br />of the SOD area. <br />3.1.3.3 Drv Fork <br />• <br />Dry Fork is an intermittent stream that is tributary to middle Minnesota Creek. The Dry Fork <br />drainage drains the northern portion of the un-mined SOD coal lease area and the area south of the <br />SE mine panels area adjacent to mine Panels 12, 13, and 17 (Map 2).
