Water Resources of Arkansas

Welcome to the USGS Web page that provides access to water resources information for Arkansas; this is your direct link to Arkansas water-resources data--quantity and quality of ground water, quantity and quality of surface water, and water use. You'll also find information about USGS publications and investigations conducted by the USGS and its cooperators.

Real-Time Data in Arkansas

Are you an angler, boater, water-resources manager, or other person who needs to know the amount of water
Streamflow Graph
(volume=streamflow, height at a specific location=stage) currently flowing down one of Arkansas' streams? The USGS provides realtime streamflow, stage, and precipitation information for more than 150 locations across Arkansas. This information is updated to our web page hourly via satellite. Users can view the information on graphs showing changes in streamflow or stage during a user-specified time period. Real-time water quality and ground water data also are available.

Arkansas Water Resources Information 2016 Flood

Surface Water Image The USGS in Arkansas collects a wide variety of water resource information at numerous locations all across Arkansas. These types of data include surface water quality, quantity, groundwater quality and water levels as well as various types of water use information. We are committed to making all of these data available to the public in an easily obtainable format through the use of automated retrieval processes. From the weblink above, users can easily obtain water quality information, perform rating curve retrievals, access StreamStats and much more. Additionally, information regarding applicable USGS publications and investigations conducted by the USGS here in Arkansas are also available.

No Contamination from Fayetteville Shale Exploration Found in Sampled Wells (02/04/2013 )
LITTLE ROCK, Ark. - A study that examined the water quality of 127 shallow domestic wells in the Fayetteville Shale natural gas production area of Arkansas found no groundwater contamination associated with gas production, according to a report released today by the U.S. Geological Survey.

AR USGS Gas Shale water quality broadcast (01/23/2013 )
Domestic water wells in proximity to natural gas drilling sites in north central Arkansas are the subject of a newly released regional baseline study. The collaborative project, coordinated by the Arkansas U.S. Geological Survey Groundwater Resources Program was the first of its kind in the nation. And as Jacqueline Froelich reports, the results were surprising.
