Terror Creek is a perennial stream with an aquatic community that includes some trout. The stream <br /> has a high gradient channel with riparian vegetation and alluvium confined to narrow bands along <br /> the channel. <br /> Stevens Gulch, East Roatcap Creek, and Coal Gulch are intermittent to ephemeral drainages that <br /> only flow part of the year. Localized deposits of colluvial material reworked by fluvial processes <br /> are present within the general area, primarily within the Stevens Gulch, West Fork Terror Creek, <br /> and Roatcap Creek drainages. These deposits are generally 20 to 30 acres in size and provide <br /> industrial (Stevens Gulch), domestic (Long Draw), and agricultural (Morrell Cow Camp) water <br /> sources (Section 2.04.7 of Volume 1). Several smaller occurrences of saturated alluvial/colluvial <br /> deposits are associated with the streams in the permit area; however, none of these are currently <br /> supporting agricultural use. <br /> The flow of water in Terror Creek and in the North Fork of the Gunnison River is strongly <br /> influenced by irrigation structures along these stream courses. The Overland Ditch intercepts and <br /> distributes water from the upper reaches of Terror Creek. The flow in the North Fork is controlled <br /> by Paonia Reservoir and water withdrawals by several irrigation ditches: the Fire Mountain Canal, <br /> Stewart Ditch, Farmers Ditch, and Paonia Ditch. In addition,there are two pipelines that currently <br /> withdraw or historically withdrew water from the Stevens Gulch Well Field. The first is currently <br /> in operation and is operated by the Pitkin Mesa Pipeline Company. The second pipeline carried <br /> water from the Stevens Gulch Well Field to the site West Mine portal facility. <br /> There are springs and ponds within the permit and hydrologically adjacent area of the Bowie No. <br /> 1 Mine. It appears that most of these springs and ponds are intermittent and depend upon seasonal <br /> precipitation and long-term weather patterns. The source of most of the springs appears to be <br /> related to landslide complexes, faults and fractures, areas of colluvium/alluvium where <br /> groundwater has accumulated, or the discharge points at the contact of the Rollins sandstone with <br /> the lenticular sandstones of the Mesaverde Formation. <br /> Water Rights and Replacement - Rules 2.04.7(3), 2.05.6(3)(ii), 2.07.6(2)(c), 4.05.15 <br /> Water rights and associated mitigation plans are found in Section 2.04.7 and Section 2.05.6 in <br /> Volume I of the PAP. Detailed tabulations and discussions of water rights and mitigation plans <br /> are documented in Volumes 5 and 5A. <br /> The Bowie No. 1 Mine could potentially damage water rights in three ways. Water for use within <br /> the mine is derived from an alluvial well field in Stevens Gulch. Drawdown of this alluvium could <br /> affect flows in Stevens Gulch and in the North Fork of the Gunnison. Over a hundred springs and <br /> spring-fed or runoff-fed stockponds cover the permit area, and many are found in the affected area. <br /> Subsidence could affect the structural integrity of these ponds or interrupt flow to springs. Lastly, <br /> mine inflows from streams along fractures could diminish adjacent surface water flows. <br /> During the permit renewal process of 1993, it was noted that the Bowie No. I Mine was consuming <br /> approximately 30,000 gpd (as proposed in their original permit application) for use at the mine. <br /> II <br />
