Description of Water Resources <br /> ' The surface water drainage on the affected lands <br /> consists entirely of rainfall and melting snow which <br /> flows into Cash Gulch. During most of the year this <br /> ' flow is intermittent, and it seldom reaches the drainage <br /> culvert that passes beneath County Road No. 89. Any <br /> water flowing from this permitted area must progress a <br /> distance of at least 3, 300 feet to reach the drainage <br /> culvert. <br /> Because of the crystalline nature of the Boulder Creek <br /> ' granite, the ground water that is found in the bedrock <br /> is only present where the granite has been fractured. <br /> Generally, the openings of these fractures (joints and <br /> t faults) decrease in size with increasing depth, and the <br /> chances of obtaining water are significantly reduced <br /> below a depth of 300 feet. This crystalline bedrock has <br /> ' a very limited water storage capacity, and most of the <br /> remaining water that falls as precipitation is returned <br /> to the atmosphere by evapotranspiration. The ground <br /> water that is present in these rocks probably migrates <br /> ' downward and laterally through a northeast-southwest <br /> trending fracture system towards the area above Cash <br /> Gulch. The presence of a small spring several hundred <br /> ' feet below the Hazel A. adit tends to support this <br /> observation. The flow from this spring varies <br /> considerably with the time of the year. It usually <br /> decreases throughout the summer and fall as the amount <br /> ' of water stored in the fracture system also decreases. <br /> The U. S. Bureau of Mines drilled five test holes 200 <br /> feet south of the proposed tailings impoundment area, <br /> and monitored the amount of ground water that flowed <br /> into these drill holes. These tests established that <br /> ' the ground water level dropped from 53 feet to 86 feet <br />
