Download or read book Recharge Area and Geologic Controls for the Courthouse Wash-Sevenmile Spring System, Western Arches National Park, Grand County, Utah written by Hugh A. Hurlow and published by Utah Geological Survey. This book was released on 2003-12 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Courthouse-Sevenmile spring system in southwest Arches National Park supports the base flow of Courthouse Wash and a stable riparian environment that is critical to the ecology of the park and adjacent areas. Small flow volumes and location in a desert environment makes the Courthouse Wash ecohydrologic system highly vulnerable to decreases in volume and quality of recharge water. This study characterizes the hydrologic system and delineates recharge area for the system. The results will help establish limits on future ground-water appropriations west and northwest of the park, to preserve the present environmental quality and ecologic stability of Courthouse Wash This CD consists of a 55-page report and three plates at a scale of approximately 1:24,000, all in pdf format.
