Groundwater level measurements (depth to groundwater) in a critical groundwater area in northeast Arkansas. Group A well measurements are select USGS measurements during 1985-2012. Group B well measurements are select USGS and USDA-ARS Delta Water Management Research Unit well data in northeast Arkansas during 2012-2019. These data could be used to further understand groundwater levels and trends in a critical groundwater area of eastern Arkansas.

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).
