Water Year 2002 Details


Three reports were published in WY 02

  • Relations of Benthic Macroinvertebrates to Concentrations of Trace Elements in Water, Streambed Sediments, and Transplanted Bryophytes and Stream Habitat Conditions in Nonmining and Mining Areas of the Upper Colorado River Basin, Colorado, 1995-98 by Scott Mize and Jeff Deacon.
  • Traveltime Characteristics of Gore Creek and Black Gore Creek, Upper Colorado River Basin, Colorado by Jason Gurdak, Norm Spahr, and Rick Szmajter.
  • Water-Quality Data Analysis of the Upper Gunnison River Watershed, Colorado, 1989-99 by Jason Gurdak, Adrienne Greve, and Norm Spahr
  • pdf versions of these reports are available in the "publications section".

Two UCOL surface water sites are part of the NAWQA Cycle II Trends Network (see map below). This network replaces the low intensity phase sampling network of NAWQA Cycle I.

  • Site 09163500, Colorado River at Colorado-Utah state line is the outlet of the study unit. The site is an integrator for all land-use and anthropogenic affects on water quality.
  • Dry Fork of Roan Creek, station 09095300, was chosen as a reference site for the Colorado Plateau physiographic province. There is a small amount of ranching in the basin, but the site is representative of small streams in the region. This site was operated during the HIP of 1996-1998 and was reestablished in November 2000 as part of the surface water trends network.

Surface water samples were collected for the analysis of nutrient, major ion, and pesticide (State Line site) concentrations. Habitat and biological samples were collected in August at the State Line site. Due to drought conditions, habitat sampling only was accomplished during August at the Dry Fork Site.

  • Water quality and streamflow data collected at these sites were published in the 2002 Annual Data Report. This report is available as a pdf file.
  • Colorado River at Colorado-Utah State Line page 291 of the pdf file
  • Dry Fork of Roan Creek page 192 of the pdf file

Archiving of field notes, data, and publications produced during the Cycle I high intensity phase of the UCOL continued during WY 02.
