18 Surface water <br />\� 4.2 Site data acquisition <br />Previously, surface water conditions and springs and seeps have been characterized by <br />the USGS, Watec (1981), the U.S. Bureau of Reclamation (1983), Utah International <br />(1982), KEC, and JBR (1998). The WATEC, Bureau of Reclamation and Utah <br />International studies all incorporated information from a series of USGS gaging stations <br />on Jubb Creek, Wilson Creek, Taylor Creek, and Morgan Gulch. These stations were <br />active from the mid 1970s to the early 1980s. The locations of these historic gaging <br />stations are shown in Figure 4.1. The WATEC report focused on surface water flow <br />characteristics and quality in the area northeast of Moffat County Road 51. The Bureau <br />of Reclamation documents a comprehensive resource and reclamation study of the <br />Collom Gulch, which included an assessment of surface water flow, hydrology and water <br />quality. The Utah International study was undertaken to characterize surface water flow <br />and quality in the vicinity of the Colowyo Mine. KEC collected and analyzed water <br />quality samples from Jubb Creek in 1996 and 1997, and JBR undertook a survey of <br />seeps and springs between Wilson and Morgan Creeks as part of an evaluation of <br />jurisdictional wetlands and riparian habitats. <br />A baseline inventory of springs, seeps, and streams in and near the project site was <br />conducted by WMC using the methods of data acquisition and analysis described in the <br />Workplan and the SAP (Appendices 1.A and 1.13). The purpose of the inventory was to <br />define the location, flow, and water quality of existing springs, seeps, and streams in the <br />Collom study area prior to development of the mine. Stream monitoring stations were <br />located upgradient and downgradient of the proposed mine. The spring and seep <br />survey was conducted within the mine footprint and surrounding areas. <br />Monitoring activities for streams included: <br />• characterization of morphology and geology, <br />• measurement of field water quality parameters, <br />• sample collection and laboratory analysis, <br />installation of flumes, and <br />flow measurements. <br />Monitoring activities for springs and seeps included: <br />• characterization of morphology and geology, <br />• measurement of field water quality parameters, <br />• sample collection and laboratory analysis, and <br />• flow estimates. <br />(o <br />2572 -R2 <br />Colowyo Coal Company <br />Water Management Consultants <br />
