SP-2 discharges at about 2-3 gpm from the Mancos shale at an <br />elevation of 6380 feet (Figure 3.3-6). This spring, identified by i <br />the BLM, maintains a manmade pond constructed as a source of water <br />for wildlife in the area. water from this spring either evaporates <br />or becomes part of the ground water system or both. No surface <br />flow has been observed. The poor water quality is typical of <br />Mancos ground water and is similar to other ground water in the <br />area (Section 3.3.4.5 and Figure 3.3-12). The source of the <br />relatively high potentiometric head exhibited by this spring is not <br />known. Several flow paths could be postulated to provide this <br />head, but not enough data is available to determine the most likely <br />system. However, the poor water quality suggests either a long <br />and/or slow path through the Mancos shale. <br />Spring SP-3 is located in previously proposed disposal area (Figure <br />3.3-6). The spring is most likely the expression of shallow ground <br />water flow from this drainage which is forced to the surface in <br />this particular area because of relatively impermeable shallow <br />bedrock (Section 3.3.4.8). The general area of this spring is very <br />wet and seepy with several small slump features in the uncon- <br />solidated material. The water quality is again typical of other <br />ground water in this area and is almost identical to OW-9 (Figure <br />3.3-12). <br />The Colorado River has eroded through the main hogback at New <br />Castle and exposed the edges of many of the potentially water- <br />bearing geologic units. It has been MLR's concern that springs and <br />or seeps may occur in this area. An investigation, both on the <br />ground and with color infra-red photographs, did not locate any <br />spring or seep areas. If flow to the surface system is occurring <br />in this area, it is most likely below a thick cover of alluvial and <br />colluvial material. <br />3.3.4.8 Ground Water Use <br />Ground water use in the vicinity of the permit area is restricted <br />NCBC - Coal Ridge #1 3-34 ASC/1145/900301 <br />
