These data have been collected as part of a cooperative project in between the U.S. Geological Survey, Colorado Springs Utilities, and Colorado Springs City Engineering. This project began in 2005 and has collected macroinvertebrate samples from Fountain Creek and its tributaries to monitor the biological condition of this watershed. Provided in this data release are Multimetric Index (MMI) values of aquatic macroinvertebrate assemblages using four different sampling methods. There are two subsets of these data included: (1) MMI values of macroinvertebrate data collected from 2010 to 2012 at 15 sites as part of an invertebrate sample method comparison Scientific Investigations Report (SIR) titled “Comparability...

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...

Description of Work Determine the relative sensitivity of two species of amphibians (i.e. Wood Frogs Rana sylvatica, Cricket Frogs Acris crepitans blanchardi, American Toad Bufo americana) to exposure to acute and chronic levels of nitrate, nitrite and ammonia. This data will be used to evaluate the current ammonia criteria and for possible inclusion in the development of criteria for nitrite and nitrate.

This dataset includes bird species, invertebrate order and family, sample identification codes, capture date, latitude, longitude, habitat, site name, bird age, total mercury concentrations in bird blood, and methylmercury concentrations in whole body aquatic invertebrates.

Description of Work The work completed for this template will provide the following information: 1) Generate acute and chronic toxicity data for freshwater mussels and snails to enhance the protection of listed/endangered species in the GL basin; 2) Refine methods and conduct acute and chronic toxicity tests on amphibians; 3) Develop and test methods for conducting chronic toxicity tests for mayflies.
