Output datasets of ecological communities (invertebrates and fish), streamflow, habitat, and water quality to examine the presence of trends in ecological communities from the Fountain Creek Basin, Colorado, USA, 2003-2016

These data were used for an analysis as part of a long-term project monitoring the biological communities, habitat, and water quality of the Fountain Creek Basin. Biology, habitat, and water quality data have been collected at 10 sites starting in 2003. These data include annual samples of aquatic invertebrate communities, fish communities, water quality, and quantitative riverine habitat collected from 2003-2016. These data will provide insight into trends in biological communities from 2003-2016 and relationships between biological communities and abiotic variables (antecedent streamflow, physical habitat, and water quality). This USGS data release contains all the input and output data and files necessary to reproduce results of the report describing an analysis of ecological trends from 2003-2016 in the Fountain Creek Basin, Colorado, USA (https://doi.org/10.3133/sir20175162). Data preparation of these data files is fully described in the report mentioned previously. These data are outputs from the two-step trend analysis and provide the statistical measures of trend significance, potential drivers of trends, and the change in each biological metric over this trend period (2003-2016).
