<br />' 2.0 Hydrologic Data Interpretation & Impact Assessment for Per- <br />, mit Area and Adjacent Areas <br />t This section contains an analysis of hydrologic data <br /> gathered during Water Year 1983; an assessment of impacts of <br />' mining on the quality and quantity of water in surface <br /> streams, springs, ground water aquifers; mine inflows and <br /> 1983 <br />i <br />f <br /> , and an est <br />mate o <br />poten- <br />discharges during Water Year <br />t tial impacts of mining on these waters during the remaining <br /> 5-year permit term. The initial five year permit area is <br />~ ' shown in Exhibit I. The permit area is drained by several <br /> northward flowing ephemeral tributaries to the North Fork. <br /> <br /> Assessment of impacts typically involves comparison of data <br />f with baseline conditions. Since no mining activity will <br />' occur in the Minnesota Creek basin during this term of per- <br /> mit, monitoring data for Water Year 1983 from the Minnesota <br />' Creek basin is considered an extension of baseline monitor- <br /> ing. <br />' <br /> Surface water, springs, and groundwater are considered sepa- <br />' rately even though they are interrelated. The report at- <br /> tempts to show the interrelationships that are significant <br />1 b <br />S <br /> or could <br />e expected. <br />ince mine water and groundwater are <br />' so interrelated, they are discussed together. <br /> <br /> <br />-16- <br />1 <br />
