What data are available to download from the National Aquatic Resource Surveys?
Data collected during the National Aquatic Resource Surveys are available to download. Data are provided in flat files (csv) and are organized by indicator. The table below shows the parameters that were collected for each of the survey years and water resource types. Sort the table by data file type or by water resource type to view the available files. Users of the data are encouraged to review the Technical Reports, Field and Laboratory Manuals, and metadata files to understand the types of data available and how they were collected or measured.
