This data set was developed by a cooperative project between the U.S. Geological Survey, Eagle County, the Eagle River Water and Sanitation District, the Town of Eagle, the Town of Gypsum, and the Upper Eagle Regional Water Authority. This project was designed to evaluate potential land-development effects on groundwater and surface-water resources so that informed land-use and water management decisions can be made. The boundary of the ERWVFA was developed by combining information from two data sources. The first data source was a 1:250,000-scale geologic map of the Leadville quadrangle developed by Day and others (1999). The location of Quaternary sediments was used as a first approximation of the ERWVFA. The boundary of the ERWVFA was further refined by overlaying the geologic map with Digital Raster Graphic (DRG) scanned images of 1:24,000 topographic maps (U.S. Geological Survey, 2001). Where appropriate, the boundary of the ERWVFA was remapped to correspond with the edge of the valley-fill aquifer marked by an abrupt change in topography at the edge of the valley floor throughout the Eagle River watershed. The boundary of the ERWVFA more closely resembles a hydrogeomorphic region presented by Rupert (2003, p. 8) because it is based upon general geographic extents of geologic materials and not on an actual aquifer location as would be determined through a rigorous hydrogeologic investigation. Purpose: The purpose of this vector data set is to delineate the approximate boundary of the Eagle River watershed valley-fill aquifer, Eagle County, North-Central Colorado, 2006-2007. Supplemental_Information: Please refer to the following associated publication for a complete description of how this data set was developed: Rupert, M.G., and Plummer, L.N., 2009, Groundwater quality, age, and probability of contamination, Eagle River Watershed Valley-Fill Aquifer, North-Central Colorado, 2006-2007: U.S. Geological Survey Scientific Investigations Report 2009-5082, 59 ., accessed August 11, 2009, at http://pubs.usgs.gov/sir/2009/5082/. This data set was developed to establish the study-area extent for three associated raster data sets that were developed as part of this study: (1) The probability of elevated nitrate concentrations in groundwater (sir090582_no3). (2) The probability of unmixed young groundwater (defined using chlorofluorocarbon-11 concentrations and tritium activities)(sir090582_mix). (3) The probability of elevated volatile organic compound (VOC) concentrations in groundwater (sir090582_voc).

As such, this aquifer boundary should be considered diagrammatic in nature. Point_of_Contact: (Warning: Although accurate at the time of production, this information may have become obsolete.

Completeness_Report: The locations of the arcs should be considered diagrammatic in nature because they are based upon general geographic extents of geologic materials and not on an actual aquifer location as would be determined through a rigorous hydrogeologic investigation. In many locations, the arcs were digitized on a computer screen using digital raster graphics files of the 1:24,000 scale topographic maps as the background.
