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: This digital dataset represents the field locations of sediment, water, benthic macroinvertebrate, and copepod samples collected in streams by the U.S. Geological Survey (USGS) from July 2004 - September 2007 for the Central Colorado Assessment Project (CCAP) environmental assessment. Samples collected in the study area, a 20,800 square mile (53,800 square kilometers) region of central Colorado, were from 229 watersheds selected for specific geologic conditions and (or) the presence or absence of historical mining activity. These sample sites are generally in upland areas of watersheds underlain by Cretaceous and older rocks. The samples were analyzed to evaluate if weathering of rocks underlying watersheds results in water and sediment geochemistry that affects aquatic ecosystems or human health. About 30 percent of the watersheds were sampled more than once to evaluate annual variations for sample collection bias. In addition, a small number of samples were collected from larger drainage basins to evaluate metal attenuation and dilution downstream from mining districts for large hydrothermally altered areas. Purpose: Points in this dataset represent the field locations where stream sediment, water, benthic macroinvertebrate, and copepod samples were collected. Samples were analyzed for geochemical composition and used to 1) compare the relationship between surface-water geochemistry and aquatic fauna in mined, prospected, and unmined watersheds; and 2) to evaluate metal attenuation and dilution downstream from mining districts for large hydrothermally altered areas. 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.

Publication_Date: 2010 Title: Central Colorado Assessment Project (CCAP) - Geochemical data for rock, sediment, soil, and concentrate sample media Edition: 1.0 Geospatial_Data_Presentation_Form: document Series_Information: Series_Name: USGS Data Series Issue_Identification: DS-509 Publication_Information: Publication_Place: Denver, CO Publisher: U.S. Geological Survey Online_Linkage: http://pubs.usgs.gov/ds/509/ Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Queries were used to check that attributes cross referenced both internally and with associated tables as intended. Attributes values were checked and evaluated as part of the review process associated with the publication of the source report. Logical_Consistency_Report: A site is a single geographic location where water, sediment, benthic macroinvertebrate and (or) copepod samples were obtained. Multiple points at the same geographic coordinates indicate where samples were obtained over multiple years. The identification of the first sample acquired at a site is used as the general identification of the field site Completeness_Report: Samples were collected from a 20,800 square mile (53,800 square kilometers) region of central Colorado. About 80% of the samples were collected from 229 small watersheds selected for specific geologic conditions and 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: Spatial 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, benthic macroinvertebrate, and (or) copepod 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 features in this data set. Field blanks, collected and processed for quality assurance purposes, were assigned an arbitrary location outside the project area of N 40 degrees, W 105 degrees. Attributes identifying the sample(s), the field site, and the watershed were added by the authors. Other attributes include a description and observations at the field site and date of sample collection. Chemical information, watershed boundaries, and geology related to the sample locations are presented as separate layers in the geodatabase.
