Geologic maps by the U.S.G.S CScott and Taylor, 1974 and Scott, Taylor, Epis and Wobus, 1978) show that bedrock fonretlons outcrop In the valley of Newlin Creek from where It exits the mointalns, across the penult Brea, and downstream Lo Its confluence with the Arkansas River. Field exarinattan of the valley across Lhe permit area Indicates a nearly contirxious allwial fill, and no outcrops were Identified. It Is felt that recent-age ailwtum should be mapped in the valley to a point Just downstream (northeast) from the northeast corner of the penntt area where bedrock outcrops can be identified In the valley walls. The valley of Newlin Creek across the permit area Is more heavily forested with pine and Juniper than the pediment capped area on either side. Occasional Cottonwood trees exist within the valley. These may indicate sane subsurface flay within the allwial deposits of the • valley. The dry face of the excavation Indicates minimal subsurface flows of water, which are for the most part depleted by Lhe vegetation growing on the valley floor. The lack of continuous flow In Newlin Creek Is due to diversions by the City of Florence. This does rot leave enough water to create significant subsurface flow In the alluvium. Newlin Creek Itself only flows rarely below the City of Florence's diversion structures. Very little or no water Is physically available for agricultural purposes along the lower reaches of New11n Creek. Mo water rights exist an Newlin Creek belay the Florence Diversions, and additional appropriations would not be allowed. The rocky nature of Lhe valley floor, lack of contirxious soil cover, heavy forestation of Lhe valley - floor, and lack of available water rights would preclude using Lhe valley of Newlin Creek for agricultural purposes. Across the permit area Newlin Creek can geomorphically said to be flowing an an allwial valley floor, but agriculturally the valley does not entirely fit the definition of AVF persuant to Section 2.06.8.3 of the Mined land Reclamation Applicator. Surface activities of the pennittee should have { ro significant affect on either surface runoff or subsurface flaw to the valley of Newlin Creek.
