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 primary field locations where sediment, water, and (or) benthic macroinvertebrate samples were collected by the U.S. Geological Survey from small basins or larger river systems for the Central Colorado Assessment Project (CCAP). The samples, collected from July 2004 - September 2007 from a 20,800 square mile (53,800 square kilometers) region of central Colorado, were mostly from 229 small watersheds basins selected for specific geologic conditions and (or) the presence or absence of historical mining activity. A smaller number of samples were collected along longitudinal profiles of larger river systems, such as the Cache la Poudre and Arkansas Rivers, to evaluate metal attenuation and dilution downstream from mining districts or large hydrothermally altered areas. About 33 percent of the sites were sampled more than once to evaluate annual variations or sample collection bias. Purpose: Points in this dataset represent 253 primary field locations where stream samples were collected either from watershed basins or along longitudinal profiles of larger river systems. Replicate samples, acquired at 85 of these sites over multiple years, are reported in addition to characteristics of the watershed above a given sample location. Lithogeochemical units, grouped into 19 units characterized by common rock type and chemistry, are also reported for each watershed. 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 and (or) benthic macroinvertebrate sample(s) were obtained. A site is represented by a single point, even when replicate samples were obtained over multiple years at the site. The identification of the first sample acquired at a site is also used as the 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 occasionally were 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, and benthic macroinvertebrate samples were collected from suitable sites from July 2004 to September 2007. The sample location of the first sample collected at a site was digitally recorded with hand-held GPS devices and imported into ArcGIS to produce the point features in this data set. The identifications of replicate samples collected at a site were added as attribute fields. Other attributes summarizing sample location, elevation, and type of site (basin for longitudinal) were added by the authors. Attributes describing watershed and (or) basin characteristics, such as areas of geologic units, were obtained by modeling the watershed area upstream of the sample point (using 10-meter digital elevation model (DEM) data and ArcHydro software), and intersecting the resulting watershed boundary with a geologic feature layer.
