<br />i <br />~_. <br />the laver NSB. Soils are irregular silty sarxls, which are generally <br />shadow (less than 5 feet) and very irregular in occurance much as the <br />alluvium. No mappable valley floor deposits of significance exist in <br />the North Sub-Basin. No proposed or existing surface activities are to <br />take place within the NSB on the permit area. Undergro~u~d mining and <br />corrected surface operations not associated with Lhts permit application <br />exist and have existed within the limits of Lhe NSB. <br />South Sub-Basin (SSB) <br />The South Sub-Basin (SSB) Is made up of five CS) intermittent <br />streams (designated first~rder) which form a second~rder stream <br />CMagPie Creek)that flows into Newlin Creek Just 300. feet or so above Its <br />confluence with the sub-basin North. This basin covers an area of 2.85 <br />square miles and is roughly wedge-shaped with the point to the <br />northeast. The basin in nearly 20,000 feet long and over 7,000 feet <br />wide at its widest point. The basin lies southeast of Newlin Creek. <br />The remaining drainage basin contributing to Newlin Creek between the <br />NSB and SSB Is in the form of a narrow strip 100 to 1,400 feet wide, <br />across the penni t area. <br />The longest stream course of the SSB Is approximately 21,200 feet or <br />4.02 miles with an average gradient of 608 feet per mile. The highest <br />point on the basin perimeter Is elevation 8,763, the confluence with <br />Newlin Creek is at about 5,860. The three C3) highest contributing <br />streams range from 0.91 mile to 2.18 miles in length with average <br />gradient rates from 555 feet per mile to 995 feet per mile respecLlvelY. <br />The lower two (2.) contributing streams have lengths of 2.20 miles and <br />1.86 miles and average gradient rates of 545 feet per mile and 293 feet <br />per mile respectively. The average gradient rate of the second~rder <br />stream below the 5 contributing streams is 320 feet per mile. The <br />• average length of the first-order streams In the SSB is about twice that <br />of those to the NSB (I.85 miles to 0.87 mile). <br />~ Topographically the stream valleys of the SSB are similar to those <br />of the NSB.
