Surface Water - Surface water information may be found in Volume I, pages 42 to 47 of Section 2.04, pages 114 to 135 of Section 2.05.6, and in Volume 4. Water rights tabulations and an augmentation plan are found in Volumes 5 and SA. Annual hydrologic reports have been prepared since 1982 and exist asstand- alone volumes. For a description of the surface water hydrology of the mine permit azea and a discussion of the impacts of mining on surface water, please refer to the Hydrologic Balance and Probable Hydrologic Consequences portions of Section B of this document. BRL's baseline surface water collection for the permit area consisted of reviewing existing baseline studies on the area, compiling a list of water rights on file with the State Engineer, identifying water resources using aerial photographs, and actual on-the-ground surveys. In the 1988 Findings, only one concern with the baseline study that pertained to a proposed area to be mined outside that five-year permit term was noted. CWI had not obtained right of entry to conduct on-the-ground baseline surveys on two tracts of land totalling 286 acres within the East Roatcap Creek drainage basin. COVCC obtained the required rights of entry during 1992-93 and performed ground reconnaissance for surface water sources on these areas as baseline data for Permit Revision No. 3. The Bowie No. I Mine permit area is drained by East Roatcap Creek, West Roatcap Creek, Main Roatcap Creek, Steven's Gulch, Coal Gulch, and Terror Creek, all of which are tributaries to the North Fork of the Gunnison. Terror Creek is a perennial stream with an aquatic community that includes some trout. The stream has a high gradient channel with riparian vegetation and alluvium confined to narrow bands along the channel. Steven's Gulch, East Roatcap Creek, and Coal Gulch are intermittent to ephemeral drainages that only flow part of the year. Localized deposits of colluvial material reworked by fluvial processes are present within the general area, primarily within the Steven's Gulch, West Fork Terror Creek, and Roatcap Creek drainages. These deposits are generally 20 to 30 acres in size and provide industrial (Steven's Gulch), domestic (Long Draw), and agricultural (Morrell Cow Camp) water sources (page 39, Section 2.04.7 of Volume 1). Several smaller occurrences of saturated alluvial/colluvial deposits are associated with the streams in the permit area; however, none of these is currently supporting agricultural use. The flow of water in Terror Creek and in the North Fork of the Gunnison River is strongly influenced by irrigation structures along these stream courses. The Overland Ditch intercepts and distributes water from the upper reaches of Terror Creek. The flow in the North Fork is controlled by Paonia Reservoir and water withdrawals by several irrigation ditches -the Fire Mountain Canal, Stewart Ditch, Farmers Ditch, and Paonia Ditch. [n addition, there are two pipelines that will withdraw water from the Steven's Gulch Well Field. The first is currently in operation and is operated by the Pitkin Mesa Pipeline Company. The second pipeline carries water from the Steven's Gulch Well Field to the site of the proposed Roatcap Creek portal facility. There are many springs and numerous ponds within the permit and hydrologically adjacent area of the Bowie No. 1 Mine. It appears that most of these springs and ponds aze intermittent and depend upon seasonal precipitation and long-term weather patterns. The source of most of the springs appears to be related to landslide complexes, faults and fractures, areas of colluvium/ alluvium where ground water has accumulated, or the discharge points at the contact of the Rollins sandstone with the lenticular sandstones of the Mesaverde Formation. 14
