Adequate water resources are vital for municipal needs in the Cumberland River watershed. As a result of continuing population growth, moderate to extreme droughts and floods, demands for competing water resources, and aging infrastructure, the evaluation of ongoing water-resources issues has become increasingly important to Federal, State, and local water-resources managers. In order to assist lo

The Nacatoch Sand in northeastern and southwestern Arkansas and the Tokio Formation in southwestern Arkansas are sources of groundwater for agricultural, domestic, industrial, and public use. Water-level altitudes measured in 51 wells completed in the Nacatoch Sand and 42 wells completed in the Tokio Formation during 2014 and 2015 were used to compile potentiometric-surface maps of the two areas.

The U.S. Geological Survey, in cooperation with the Reservoir Fisheries Habitat Partnership, combined multiple national databases for the purpose of calculating new morphological metrics not included in the original databases for 3,828 reservoirs. These new metrics include, but are not limited to, shoreline development index, index of basin permanence, and development of volume and other descript

The nature of carbon (C) cycling in the vadose zone where groundwater is in contact with abundant gas-filled voids is poorly understood. The objective of this study was to trace C cycling in a karst landscape using stable-C isotopes, with emphasis on a shallow groundwater flow path through the soil, to an underlying cave, and to the spring outlet of a cave stream in the Ozark Plateaus of northwest

Heavy rainfall occurred across Louisiana in August, 2016 as a result of a slow-moving area of low pressure and a high amount of atmospheric moisture. The storm caused major flooding in the southern portions of Louisiana including areas surrounding Baton Rouge and Lafayette. Flooding occurred along the rivers such as the Amite, Comite, Tangipahoa, Tickfaw, Vermilion, and Mermentau. Over 31 inches

This dataset combines three Federal datasets of thermoelectric, non-industrial, power plant water withdrawals and associated plant information for the United States in 2010, excluding Puerto Rico and the U.S. Virgin Islands. Historically, thermoelectric water withdrawal has been estimated by the Department of Energy's Energy Information Administration (EIA) through surveys of plant operator-report

A hydrogeologic framework was constructed to represent the altitudes and thicknesses of hydrogeologic units within the Ozark Plateaus aquifer system (hereinafter referred to as the Ozark system). The Ozark system study area is nearly 70,000 square miles and includes parts of Arkansas, Kansas, Missouri, and Oklahoma. Nine hydrogeologic units were selected for delineation within the Ozark system and

Groundwater is an often overlooked freshwater resource compared to surface water, but groundwater is used widely across the United States, especially during periods of drought. If groundwater models can successfully simulate past conditions, they may be used to evaluate potential future pumping scenarios or climate conditions, thus providing a valuable planning tool for water-resource managers. Qu

Springs and sinkholes in the Ozark Plateaus Physiographic Province (Ozarks) in Arkansas were digitized from 1:24,000 scale topographic maps to produce a digital dataset of karst features. Karst landscapes generally are created from bedrock dissolution that results in distinctive landforms, including sinkholes, springs, caves, and sinking streams, and a high degree of interaction between surface wa

From October 2007 through September 2010, the U.S. Geological Survey (USGS) in cooperation with the Tennessee Duck River Development Agency monitored water quality at 24 sites in the Upper Duck River Watershed. Water samples were collected and analyzed for carbonate hardness, acid neutralizing capacity, chloride, ammonia, nitrate, nitrite, phosphorus, boron, bromine, Enterococci and Escherichia co

This geospatial dataset includes one point feature class file and associated FGDC-compliant metadata representing datasets to support development of ecological limit functions for the Cumberland Plateau in northeastern Middle Tennessee and southeastern Kentucky. Information contained within the dataset represents values of basin characteristics, estimates of streamflow characteristics, measures o
