Water-Quality Summary for the Big Thompson and Gunnison River Basin

Summaries of water-quality monitoring data are now available for the Big Thompson and Gunnison River Basins of Colorado. For each basin, current data from a network of sites are compared to previously collected data and instream standards. Lowess curves are provided on plots for selected constituents where a sufficient period of record and limited censored data are available.

A National Assessment of Changes in Chloride, Dissolved Solids, and Nitrate in Groundwater

Groundwater-quality monitoring data collected by the USGS National Water-Quality Assessment Program (NAWQA) from many regions of the United States are being synthesized into a national assessment of groundwater-quality trends. NAWQA Groundwater-Quality Trends

Colorado Water-Quality Data Repository (CWQDR)

An internet-based data management system that integrates ambient water-quality data from a variety of sources including government agencies, stakeholder groups, and private entities.
