the snowmelt period of Spring 1995, and may be considered an intermittent stream. Stephans <br />Draw is also an intermittent stream, and Stockpond P-1 is located along Stephans Draw. <br />The drainages of A-Gulch, B-Gulch, C-Gulch, D-Gulch, Sheep Corral Gulch and a portion of <br />Dove Gulch probably exhibit ephemeral flow regimes. A portion of Dove Gulch can be <br />considered perennial. <br />There aze twelve (12) stock ponds located in the permit and adjacent areas. These include Pond <br />P-1, mentioned above, and al] of the ponds are manmade. The ponds co]}ect spring season <br />runoff, and any available seep water. <br />Groundwater in the area is located within the alluvial deposits along the North Fork of the <br />Gunnison River and Hubbazd and Terror Creeks, within the steep sloped colluvial deposits found <br />within some of the drainages, in perched water zones located within the lenticulaz sandstones of <br />the Mesa Verde formation and in the Rollins Sandstone. The Rollins Sandstone is a recognized <br />aquifer in the azea. <br />The groundwater associated with the alluvial deposits of the North Fork of the Gunnison River <br />has been developed for domestic and agricultural uses. The localized groundwater resources <br />associated with the alluvial deposits of Hubbard and Terror Creeks are not significantly <br />developed. The groundwater associated with local colluvial deposits is rechazged by snowmelt, <br />and the water dischazges through local intermittent springs and seeps. Most of this colluvial <br />water is lost due to evaporation. <br />Bedrock groundwater is not abundant in the permit azea. The groundwaters of the locally <br />perched bedrock water zones and of the Rollins Sandstone aze not significantly developed in the <br />permit and surrounding azea, due to relatively poor water quality and low potential quantity <br />yields. The general bedrock groundwater flow direction in the sandstone strata of the Mesaverde <br />formation is from the rechazge azea near the outcrop of these strata, north towazd the tower parts <br />of the basin. <br />Climatological Information - <br />Detailed climate information is presented in Section 2.04.8 of the Bowie No. 2 Mine permit <br />application document, and the information is summarized below. The nearest weather station to <br />the permit azea was the Wilcox Ranch Station, located east of the old Bowie townsite, in the <br />Hubbazd Creek Drainage. The period of record for this station is from 1948 to 1983, and the <br />average annual precipitation of record for this station is 18.50 inches. The station was moved to <br />the West Elk Mine in November 1983, and the station is now referred to as the Somerset IE <br />Station. Other weather stations in the area were the Paonia 3SE and Paonia ISW stations. The <br />Paonia 3SE and Paonia ISW stations recorded data for the periods 1905 to 1957, and 1957 to <br />1993, respectively. <br />The average minimum temperature in the azea is about 45 degrees (Fahrenheit), with the lowest <br />temperature of -28 degrees recorded in Paonia during 1913. The average high temperature in the <br />1a <br />
