136 feet from the Gold Hill Mill Pipeline. There are no other man-made <br /> structures within two hundred (200) feet of the proposed amended permit <br /> area boundaries. <br /> (3) Description of Water Resources of Area <br /> Surface Water Resources <br /> The surface water drainage on the affected lands is generally ephemeral, <br /> consisting almost entirely of runoff originating as rainfall and/or melting <br /> snow which flows into Akins (Lick Skillet) Gulch. Most of the year this flow <br /> is intermittent, and it only reaches Left Hand Creek during the spring <br /> runoff and periods of high precipitation. There is a difference in altitude of <br /> 737 feet between the Times Mine portal and Left Hand Creek. Any <br /> intermittent surface water flowing from the Times Mine area must progress <br /> a distance of at least 4,627 feet to reach Left Hand Creek. <br /> Left Hand Creek is the only significant perennial water feature in the Gold <br /> Hill area. <br /> Water quality sampling and analytical data from sampling the water in Left <br /> Hand Creek is contained within the MLRD Permits No. M-1994-117 and <br /> No. M-1983-141. <br /> Groundwater Resources <br /> Groundwater present in the Gold Hill area of Boulder County is typified by <br /> fracture zone occurrences. Due to the crystalline nature of the Boulder <br /> Creek granite, groundwater is found only in bedrock areas where the <br /> granite has been fractured. Generally, the openings of these fractures <br /> Qoints and faults) decrease in size with increasing depth, and the <br /> probability of encountering significant water bearing zones is greatly <br /> reduced at depths generally in excess of 300 feet. <br /> The crystalline bedrock has a very limited storage capacity, and most of <br /> the water that is received through precipitation is returned to the <br /> atmosphere through evapotranspiration. The groundwater that is present <br /> within the Boulder Creek granite tends to migrate downward and laterally <br /> through a northeast to southwest trending fracture system towards the <br /> general area north of Akins (Lick Skillet) Gulch. Nothing associated with <br /> the installation of the Left Hand Creek Pump Station, Gold Hill Mill <br /> Pipeline, or the Times Mine adit portal will affect the groundwater <br /> resources in this area. <br /> Exhibit B—Site Description 3 <br />
