Climate variability, changing land use and management, and dynamic policy environments are the main reasons why long-term water quality data sets are needed to understand and predict possible water quality outcomes to alternative future scenarios. Such data sets were acquired by the USDA-ARS in three watersheds in Oklahoma: the Southern Great Plains Research Watershed (SGPRW), the Little Washita River Experimental Watershed (LWREW), and the Fort Cobb Reservoir Experimental Watershed (FCREW).

This dataset links to the Long Term Ecological Research (LTER) Florida Coastal Everglades (FCE) Core Research Data Table of Contents (DTOC). The DTOC contains links to 173 individual datasets, which may be queried from the DTOC page.
