Arkansas StreamStats -- A Web Map Application for Stream Basin Characteristics and Streamflow Statistics
Arkansas StreamStats is a Web-enabled geographic information system (GIS) application that makes it easy for users to obtain basin characteristics, streamflow statistics, and other information for USGS streamflow-gaging stations and for any ungaged stream within Arkansas. When users select an ungaged location, StreamStats will run a GIS program to delineate the drainage basin boundary, measure basin characteristics, and estimate streamflow statistics based on USGS streamflow-prediction methods. Users can download the GIS feature class of the drainage basin boundary with attributes including the measured basin characteristics and estimated streamflow statistics.

Sparta Recovery Project
The Sparta aquifer is Union County's only source of municipal and industrial ground water. Since development began in the early 1920's ground-water levels have declined more than 390 feet in some areas. As a result, Union was among five southern Arkansas counties designated as the state's first "Critical Ground Water Area" in 1996.
