Comparison of 2016–17 water years and historical water-quality data, Upper Gunnison River Basin, Colorado
This web product summarizes water-quality data collected during water years 1994-2017 for a network of sites in the upper Gunnison River Basin of Colorado (fig. 1 and table 1). Current data (2016-2017) for each site are compared to previously collected data and the State of Colorado instream standards. Lowess curves (Helsel and Hirsch, 2002) are provided on plots for selected constituents where a sufficient period of record and limited censored data are available.
Water-quality data in the Upper Gunnison river basin has previously been published in four formal Data Series publications (Solberg and others, 2009, 2012; Spahr and others, 2008; Spahr, 2004). Although verified and reviewed, the summaries included in this product should not be considered a formal U.S. Geological Survey publication.
