West Elk Mine 2003 Annual Hydrology Report <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 drains the western mine panel area. The Lower Gribble Gulch station was <br />established to monitor the effects of mining in the west and northwest mine panel area. <br />3.1.3 Minnesota Creek <br />3.1.3.1 Lick Creek Flume <br />Lick Creek is an ephemeral drainage tributary to upper Minnesota Creek that flows only in <br />response to storm events and spring runoff Lick Creek drains the southern part of the un-mined <br />SE coal lease area. This station was established in 1977 when MCC was planning to develop this <br />tract. The site was also established as part of the Minnesota Creek Augmentation plan. <br />3.1.3.2 Drv Fork <br />Dry Fork is an intermittent sheam tributary to middle Minnesota Creek that drains the northern un- <br />mined SE coal lease area and south of the SE mine panels azea adjacent to mine Panels 12 and 13. <br />The three monitoring sites in Dry Fork, upper, middle and lower Dry Fork were established to <br />monitor effects of mining along the drainage and to support the Minnesota Creek Augmentation <br />plan. <br />3.1.3.3 Horse Gulch and East Gulch, East of Horse Gulch <br />Horse Gulch and East Gulch, East of Horse Gulch are ephemeral drainages that are tributary to Dry <br />Fork and flow only in response to storm events and spring runoff These streams flow into, <br />Minnesota Reservoir and dram the SE mine panel area and are located witMn the un-mined SE coal <br />lease area. <br />3. L3.4 Unger and Lower Minnesota Creek <br />Minnesota Creek is the major stream that drains the southern mine area. Upper Minnesota Creek <br />station was established by the USFS in 1977 to collect baseline data for the un-mined SE coal lease <br />area and in support of the DRinnesota Creek Augmentation Plan. The upper Minnesota Creek <br />station is located up-stream of Dry Fork. The lower Minnesota Creek Station is located down <br />stream of Dry Fork. These stations also are used to monitor the hydrologic effect of mining the SE <br />mine panel area. <br /> <br />10 <br />September 2004 ~ HydroGeo, Inc. <br />
