Invertebrate, fish, and habitat data were collected as part of a cooperative project that began in 2002 between the U.S. Geological Survey, Colorado Springs Utilities, and Colorado Springs Engineering. Other entities have contributed to the project over the years including Colorado Parks and Wildlife. Data were primarily collected from up to 35 sites – 33 sites within the Fountain Creek Basin but also from two sites on the Arkansas River. The number of sites sampled each year as well as the number of annual visits during which data were collected, and sampling methods used during each visit vary. Data were collected between 2002 and 2023 and is intended to be updated annually as new data are collected and available. Users of these data are advised to read all metadata and associated documentation thoroughly to understand appropriate use and data limitations.

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.
