This report includes an analysis of the ground-water data (well and spring data) available for the Upper Colorado River Basin study unit from water years to for major cations and anions, metals and selected trace elements, and nutrients. Analysis of ground-water-quality data of the Upper Colorado River Basin, water years Denver, Colo.: U.S. Dept. of the Interior, Geological Survey: USGS Information Services [distributor], (OCoLC) Material Type: Government publication, National government publication, Internet resource: Document Type: Book, Internet. Apodaca, L.E., , Analysis of ground-water-quality data of the Upper Colorado River Basin, water years – U.S. Geological Survey Water . Streamflows are typically highest in the spring and lowest during the winter (fig. 3). The primary data-collection period for the UCOL study was water years – Streamflow during water years –97 was above average for most of the basin. Streamflow during water year was about average.

Content page for USGS Circular , Water Quality in the Upper Colorado River Basin, Colorado, –98 SUMMARY OF MAJOR FINDINGS The Upper Colorado River Basin (UCOL) of the National Water-Quality Assessment (NAWQA) Program includes square-mile drainage basin of the Colorado River upstream from the Colorado-Utah State line. Introduction. This web product summarizes water-quality data collected during water years for a network of sites on the main stem and major tributaries of the Colorado River in Colorado (fig. 1 and table 1).Current data () for each site are compared to previously collected data and the State of Colorado instream standards. Comparison of –18 water years and historical water-quality data, Colorado River Mainstem and major tributaries to the Colorado River, Colorado Definition of terms Concern levels - The three-tiered concern levels, defined below, are provided to inform watershed users to potential impairments within specific stream segments. Comparison of –17 water years and historical water-quality data, Lower Gunnison River Basin, Colorado Definition of terms Concern levels - The three-tiered concern levels, defined below, are provided to inform watershed users to potential impairments within .

This is the basic data section of a report by the U.S. Geological Survey on the water resources of the Upper Colorado River Basin. This section contains tables of duration of water discharge at stream-gaging sites, monthly and annual summaries of chemical quality and sediment data at sites of continuous record, results of chemical quality and sediment analyses at miscellaneous . The Upper Colorado River Basin is 1 of 60 study units selected for water-quality assessment by the U.S. Geological Survey as part of the National Water-Quality Assessment program. Understanding the environmental setting of the Upper Colorado River Basin study unit is important in evaluating water-quality issues in the basin. ground water withdrawals have constituted the principal water usage for at least fifteen years preceding the date of the first hearing on the proposed designation of the basin, and which in both cases is within the geographic boundaries of a designated ground water Size: 2MB. the Colorado River system to meet future Basin resource. 5. needs are even more apparent, given the likelihood of increasing demand for water throughout the Basin coupled with projections of reduced supply due to climate change. It was against this backdrop that the Colorado River Basin Water Supply and Demand Study (Study) was conducted.
