<br />Within ASA 1103 and the designated analytical areas, the identified problems <br /> <br />~~ generally are common throughout. In some instances, they are inter-related with <br />{~, <br />~ other subareas. The following is a draft summary of the problem identification <br />~ <br />~ activity of the work group and the consultants, identifying those areas where <br />~ or <br />problems or issues existn.hich may be expected to occur in the near future. <br /> <br />1. Upper Arkansas Sub-Basin (including Bear Creek drainage--Baca County, <br /> <br />Colorado). Specific problems treated in this area cover flood control and <br /> <br />conservation needs on tributary streams of Bear Creek, James Draw, Pawnee River, <br /> <br />and Wet Walnut Creek, On the mainstem of the Arkansas River, a basin problem is <br /> <br />of concern with flood control, irrigation, recreation, and fish and wildlife, <br /> <br />water quality and erosion. Phreatophytes are of some concern in the area along <br /> <br />the mainstem of the Arkansas River. In the western portion of the sub-area, <br /> <br />including Baca County, Colorado, groundwater depletions are occurring to the extent <br /> <br />that a mining situation has developed. This problem encompasses an area of eight <br /> <br />counties in Kansas and one county in Colorado. This problem is also of concern <br /> <br />to other sub-areas as well as other ASA's. <br /> <br />2. Lower Arkansas Sub-Basin. The area covers the south-central portion of <br /> <br />the Kansas area and the north-central part of the Oklahoma area. Problems associated <br /> <br />with flood control and conservation needs have been identified on tributary streams <br /> <br />of the Walnut, Chikaskia, and Salt Fork river basins. Water quality problems due <br /> <br />to natural salt areas--both chlorides and gypsum deposits--are of particular <br /> <br />concern on the mains tern and several tributary streams and rivers. Areas identified <br /> <br />with this problem include the mainstem of the Arkansas River, Ninnescah River, <br /> <br />Whitewater River, and Cow and Rattlesnake Creeks in Kansas and the Salt Fork River <br /> <br />in Oklahoma. Phreatophyte intrusion in the Salt Fork area of Oklahoma is a problem <br /> <br />with respect to both ground and surface water, In the Little Arkansas portion of the <br /> <br />area, flood control, water management, erosion, and sediment are identified problem <br /> <br />areas. <br /> <br />3~. <br />
