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 used for a two-step analysis of trends in biological communities and the abiotic drivers of these trends. All files with a _1 suffix are used for the analysis of streamflow drivers of trends in these biological communities. All files with a _2 suffix contain data from unexplained trends after the first analysis and are used for an analysis exploring if these trends are explained by water quality or habitat characteristics.

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).

These data from Evaluation and Review of Ecology-Focused Stream Studies to Support Cooperative Monitoring, Fountain Creek Basin, Colorado were used to describe temporal trends in invertebrate communities in the basin. Invertebrate data were collected at U.S. Geological Survey (USGS) sites between 1985 and 2022. Datasets include invertebrate frequency of occurrence, invertebrate tolerance index values, invertebrate multi-metric index, New Zealand mudsnial counts, and list of invertebrate species collected.
