This data package was created 2024-06-20 15:09:45 by NPSTORET and includes selected project, location, and result data.

Data are from an EPA sponsored study on the Effects of Acidification on Caged Native Brook Trout. The data derive from Keil Jason Neff’s University of Tennessee Master’s thesis entitled ‘Physiological Stress in Native Brook Trout (Salvelinus Fontinalis) During Episodic Acidification of Streams in the Great Smoky Mountains National Park’. The dataset includes 9,301 results collected from 2/10/2006 to 6/29/2008 at 6 monitoring locations comprising throughfall and stream sites at Eagle Rocks Prong, Middle Prong, and Ramsey Prong. Data contained in Great Smoky Mountains National Park NPSTORET back-end file (GRSM_NPSTORET_BE_20240510.ACCDB) were filtered to include: Organization: - GRSM: Great Smoky Mountains National Park Project: - GRSM_EPA: Effects of Acidification on Caged Native Brook Trout Station: - Include Trip QC And All Station Visit Results Value Status: - Accepted or Certified (exported as Final) or Final

The data package is organized into five data tables: - Projects.csv - describes the purpose and background of the monitoring efforts - Locations.csv - documents the attributes of the monitoring locations/stations - Results.csv - contains the field measurements, observations, and/or lab analyses for each sample/event/data grouping - HUC12.csv - enumerates the domain of allowed values for 12-digit hydrologic unit codes utilized by the Locations datatable - Characteristics.csv - enumerates the domain of characteristics available in NPSTORET to identify what was sampled, measured or observed in Results

Period of record for filtered data is 2006-02-10 to 2008-06-29. This data package is a snapshot in time of one National Park Service project. The most current data for this project, which may be more or less extensive than that in this data package, can be found on the Water Quality Portal at: https://www.waterqualitydata.us/data/Result/search?project=GRSM_EPA
