Publication_Date: 2012 Title: Geospatial database for regional environmental assessment of central Colorado Geospatial_Data_Presentation_Form: document Series_Information: Series_Name: USGS Data Series Issue_Identification: DS-614 Publication_Information: Publication_Place: Denver, CO Publisher: U.S. Geological Survey Online_Linkage: http://pubs.usgs.gov/ds/614 Description: Abstract: These data are watershed, or small catchment, boundaries at 229 locations where stream samples were collected by the U.S. Geological Survey (USGS) from July 2004 - September 2007 for the Central Colorado Assessment Project (CCAP) environmental assessment. The watershed areas range from about 1 to 165 square miles (1 to 425 square kilometers) and extend from the stream sample location to the respective drainage divide. Watersheds (modeled with ESRI Arc Hydro 1.2 for ArcGIS 9.2) were selected that were underlain by one predominant lithogeochemical rock unit, that contained large hydrothermally altered areas, or where historical mining activity was either present or absent. These watersheds were evaluated to assess whether disturbance or weathering of underlying rocks results in water and sediment geochemistry that affects aquatic ecosystems or human health. Purpose: Polygons in this dataset represent the area of a watershed extending from a stream sample location to the upstream drainage divide. The watersheds were model generated and are typically equivalent to or smaller than watersheds associated with 12-digit Hydrologic Unit Codes (1:24,000-scale). These targeted watersheds were selected because they were underlain by a predominant lithogeochemical rock unit, or by large hydrothermally altered areas, or for the presence or absence of historical mining. The watersheds were evaluated for potential influences of lithology and (or) mining activity in headwater areas on downstream water and sediment geochemistry. Supplemental_Information: The USGS conducted the Central Colorado Assessment Project (CCAP) from 2003 to 2008 to provide Federal, State, and local land management entities geoscience information to address issues related to urbanization of the Colorado Front Range Urban Corridor. Rapid population growth along the Front Range and in the CCAP region, which encompasses about 20,800 square miles (53,800 square kilometers) of central Colorado between the New Mexico and Wyoming borders (37 - 41 degrees north latitude), and from west of Denver to east of Vail, Colorado (approximately 104.8 - 106.625 degrees west longitude), has caused tremendous demand for natural resources and has created challenging land-management issues related to the wilderness/urban interface expansion. Regional CCAP data, including geologic, geochemical, geophysical, biological, and remote sensing data, were compiled to assess the availability of mineral resources; the geo-environmental effects of historical mining and wildfires; geologic controls on groundwater resources; and hazards such as landslides and flooding.

Attributes values were checked and evaluated as part of the review process associated with the publication of the source report. Logical_Consistency_Report: All watershed boundaries were model generated using ArcHydro 1.2 and 10-meter USGS National Elevation Dataset (NED) data. Less than three percent of the boundaries were subsequently modified by hand using 1:24,000 USGS digital raster graphic topographic map bases. Watershed boundaries may overlap where multiple samples were collected along a stream reach and nearby connecting tributaries. Completeness_Report: Samples were collected from a 20,800 square mile (53,800 square kilometers) region of central Colorado. Watershed boundaries were generated for about 80% of these samples, and tended to be in basins characterized by specific geologic conditions or the presence or absence of mining activity. The remaining 20% of the samples were collected from larger drainage basins to evaluate metal attenuation and dilution downstream from mining districts or large hydrothermally altered areas. Together the sample sites cover about 80% of the land area in the CCAP study area. Favorable stream sites were occasionally not sampled due to access restrictions or lack of stream flow at the time of the field visit Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Each watershed is assoicated wiith a field sample location. The coordinates of sample locations were determined from hand-held global positioning system (GPS) devices. In general, the GPS units used by field scientists recorded sample locations to within 100 feet (30 meters) of the true location. When more than one scientist collected field samples at a site on different dates, the reported location is a composite of the GPS measurements and the location is verified using a geographic information system (GIS) and digital topographic maps. Water samples were typically collected at the recorded GPS location; sediment and aquatic insect samples were usually collected within 75 feet (22 meters) of the indicated location. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The elevation of sample locations was estimated from 1:24,000-scale topographic maps with contour intervals of 40 feet (12 meters). Reported elevations are probably accurate within 20 feet (12 meters or one-half contour interval) of true elevation. Lineage: Process_Step: Process_Description: Stream sediment, water, and benthic macroinvertebrate samples were collected from suitable sites from July 2004 to September 2007. Sample locations, digitally recorded with hand-held GPS devices, were imported into ArcGIS to produce the point feature layer, "Sites_Field", in this geodatabase. A subset of sample points was selected where the upstream area was underlain by a predominant lithogeochemical unit, by hydrothermally altered areas, or where historical mining activity was either present or absent. Watershed boundaries above these selected sample sites were modeled using the point locations and National Elevation Dataset (NED) 10-meter resolution digital elevation model (DEM) data, and ArcGIS 9.2 and ArcHydro 1.2 software. A few of the modeled watersheds were hand modified using 1:24,000-scale digital topography map bases to more accurately represent a specified watershed.
