MUST SUBMIT TO THE DIVISION AN ANNUAL HYDRO- <br /> LOGIC REPORT. THIS REPORT SHALL INCLUDE AN ANALYSIS OF ALL HYDROLOGIC <br /> DATA GATHERED DURING THE YEAR, AN ASSESS14ENT OF THE IMPACTS OF MINING <br /> DURING THE YEAR, AND AN ESTIMATE OF THE PROJECTED IMPACTS OF MINING IN <br /> THE FOLLOWING YEAR. THIS REPORT SHALL ASSESS THE IMPACTS OF MINING ON <br /> THE QUALITY AND QUANTITY OF WATER IN SURFACE STREAMS, SPRINGS, GROUND- <br /> WATER AQUIFERS, MINE INFLOW AND MINE DISCHARGES. <br /> Cumulative Hydrologic Effects - Finding <br /> An assessment of the probable hydrologic consequences of the proposed mining <br /> .operation and an assessment of the probable cumulative impact of all antici- <br /> pated mining in the area on the hydrologic balance have, been made. With the <br /> above hydrologic stipulations, including those found in the alluvial valley <br /> floor determination, the proposed operation has been found to be designed to <br /> prevent material damage to the hydrologic balance outside the permit area. <br /> REFERENCES <br /> Hamon, W.
