2.04 APPLICATIQ7 F'Qt PF3tt~T FCR SDItFACE Qt @IDIItC3tD@m MINII~IG AOPIVIT~ - <br />MIlla1@I RF7QIIIRFSffSIPS FCR IITICN CAI FSNII2L2Ag2III~L RF~CFS. <br />• 2.04.7 Hydrology Description. <br />(2) Surface Water Information. <br />(a) aryl (b) (Cont'd.) <br />West Roatcap Creek is an ephemeral stream with a drainage area <br />of approximately 8.2 miles (5248 acres). Stream flows ocarr in <br />response to spring snowmelt and precipitation events. In the <br />northwestern portion of the drainage basin, run-off is captured <br />by the Overland Ditch. Available information suggests that the <br />northwest tread of West Roatcap Creek is the result of <br />antecedent geologic structure. Of the total drainage area, 562 <br />acxes, or 10.7, is in the permit area. Topography of the <br />watershed is characterized by steep or vertical canyon walls in <br />the lower portions with moderate to gently slopes in the upland <br />areas. Representative features are currently monitored for flow <br />rates and water quality parameters when accessible in accordance <br />with Volume 4, Tables 2 and 3. <br />A detailed field reconnaissance program was undertaken in <br />October, 1991, by Simon Hydro-Search, to identify all surface <br />water resources occurring within an additional 440 acres of <br />permit area added to incorporate Lease GnC-53356 into the permit <br />area. The majority of this acreage, approximately 279 acres, <br />• occurs within the Fast Roatcap Creek drainage with the remainder <br />located in the West Roatcap Creek drainage. This study also <br />revisited those lands which had previously been ina~sible due <br />to surface owner access objections. The hydrologic studies and <br />surface access docwnentation required by Stipulations 26 and 28 <br />were coccg~leted, compiled, aril su}xnitted as part of the permit <br />revision application addressing those lands incorporated into <br />the permit as a result obtaining of Lease OOC-53356. All <br />hydrologic features identified in the 1991 study are depicted in <br />Volume 4, Map No. 4-1. The final report generated by Simon <br />Hydro-search describing the surface water resources encountered <br />is included in the Volume 4, Surface Water Appendix. Tables 2 <br />and 3 in Volume 4 have been revised to incorporate those <br />representative features identified for further monitoring. <br />In summary, Stevens Gulch, East Roatcap Creek, arxl West Roatcap <br />Creek are ephemeral streams tributary to the North Fork of the <br />Gunnison River. CWI believes that aquatic life similar to that <br />in the North Fork exists in these streams when the floras reach <br />the North Fork. Following spring runoff, Stevens G7ilch is dry <br />for the most part. Main Roatcap Creek, which carries the floras <br />of Fast and West <br /> <br />'II2 93-24 Revised 12/10/93 <br />51 <br />
