ROARING FORK WATERSHED WATER-QUALITY DATA--HISTORICAL DATA RETRIEVALS

Data can be retrieved from the Roaring Fork Watershed historical data base using the selection buttons on this page. Selections can be made based on site, sample, and parameter. Sites are the locations at which data are collected. Samples are the material collected on a given date. Parameters are the types of information or constituents determined for a sample. When you are finished making selections, use the 'Get Data' button to download the data (NOTE: the get data button will not be activated until you have selected sites, sample, and parameters), use the 'Clear Selections' button to clear your selections, or use links to other pages to exit the page without retrieving data. Retrieval requests for large amounts of data may take up to one minute to process. Query results may result in less data than expected: for example, if nutrient data are requested for all sites, the resulting data retrieval will most likely not contain all sites because nutrient data have not been collected at all sites. A Database Dictionary is available which describes the contents of fields in the data base. The parameter file provides a listing of the parameters in the database.

(NOTE: Before starting a new query, ensure that all selections have been cleared by clicking on the 'Clear Selections' button.)
