LOWER MISSISSIPPI-GULF WSC - BATON ROUGE SEDIMENT LAB PRICE LIST - 2018 FISCAL YEAR
(Effective date will begin with samples received
by the Laboratory after October 1, 2017)
The U.S. Geological Survey's Groundwater Resources Program (GWRP) is conducting an assessment of groundwater availability throughout the United States to gain a better understanding of the status of the Nation's groundwater resources and how changes in water use and climate may affect those resources.
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.
Short Title: Beaver Lake 3-D Modelin
Project Chief: Reed Green
Cooperator: Beaver Water District
Project Time Frame: October 2007 - present
Beaver Lake is a large, deep-storage reservoir located in the White River Basin in northwestern Arkansas and is considered a primary watershed of concern in Arkansas. As such, information is needed to assess water quality, especially nutrient enrichment, nutrient-algal relations, turbidity, and sediment issues within the system.
Short Title: Beaver Lake Water Quality
Project Chief: Reed Green
Cooperator: Beaver Water District
Project Time Frame: 2000 - present
Beaver Lake, completed in 1963, is located in northwestern Arkansas and receives a majority of its water from three tributaries of the White River (White River, Middle Fork White River, and West Fork White River), Richland Creek, and War Eagle Creek.
Short Title: Ground-Water Data Network
Project Chief: Anna Nottmeier
Project Time Frame: 1985 - present
Arkansas is the fourth largest user of ground water in the United States. Since the 1920’s, ground-water withdrawals have increased while water levels have declined. Long term water-level records are needed to evaluate the effects of climatic variations on the recharge and discharge from ground-water systems and are necessary in the construction and calibration of accurate ground-water flow models to allow prediction of future conditions.
Short Title: Hot Springs Flood Warning System
Project Chief: Joseph Fleming
Cooperator: City of Hot Springs
Project Time Frame: 2008- present
In May 1990, a series of severe thunderstorms developed in the vicinity of Hot Springs with a total of 13.25 inches of rainfall measured at the National Park Service rainfall gage. Severe flooding caused by the excessive rainfall damaged numerous bridges and homes throughout the region and resulted in the loss of one life. Floodwaters 2 to 4 feet deep flowed through the historic downtown area of Hot Springs, causing extensive damage to private and public property.
Short Title: Lakes Maumelle and Winona
Project Chief: William Green
Cooperator: Central Arkansas Water
Project Time Frame: 1989 - present
Lakes Maumelle and Winona are water-supply reservoirs for the Little Rock and North Little Rock metropolitan areas in central Arkansas. In addition to water supply, the reservoirs are used for recreation and fish and wildlife habitat.
Short Title: Middle Fork Study
Project Chief: William Baldwin
Cooperators: Hot Springs Village Property Owners Association, Arkansas Department of Environmental Quality, Arkansas Game and Fish Commission,Arkansas Naural Resources Commission, U.S. Bureau of Land Management, and U.S. Fish and Wildlife Service
Project Time Frame: 2003 - present
he Middle Fork of the Saline River flows through parts of Garland and Saline Counties in south-central Arkansas and is a tributary of the Saline River. The Middle Fork of the Saline River (hereafter referred to as the "Middle Fork") flows southeastward through Hot Springs Village and into Saline County, before its confluence with the Alum Fork of the Saline River.
Short Title: North Ground-Water Model
Project Chief: Phillip Hays
Cooperators: Arkansas Natural Resources Commission
Project Time Frame: 2005 - present
Several counties in eastern and southern Arkansas have been designated Critical Ground-Water Areas (areas where alluvial aquifer water levels dropped below 50 percent of the original saturated thickness or below the top of the Sparta Sand) by the Arkansas Natural Resources Commission. The expansion of the cones of depression and the consistent water-level declines indicate that ground-water withdrawals are occurring at a rate that is greater than the sustainable yield of the aquifer.
Short Title: Ozark Plateaus NAWQA
Project Chief: Billy Justus
Project Time Frame: 1991 - present
The Ozark Plateaus study unit is one of more than 50 study units that are part of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program. The long-term goals of this program are to describe the status and trends in the quality of a large, representative part of the Nation's surface- and ground-water resources, and to provide a sound, scientific understanding of the primary factors affecting the quality of these resources. The program will evaluate water quality at a wide range of spatial scales, from local to national, and will employ a multidisciplinary approach using physical, chemical and biological measurements to provide multiple lines of evidence with which to evaluate water quality.
Short Title: Sediment Data Program
Project Chief: Dwight Lasker
Cooperator: U.S. Army Corps of Engineers - Memphis District
Project Time Frame: 1997 - present
Sediment concentrations and discharges in rivers and streams must be defined and monitored for effective water resource planning and water-quality assessments. An important part of the USGS mission is to provide scientific information to manage the water resources of the Nation. Long-term sediment records help to characterize geomorphologic and physical channel changes in watersheds, evaluate the effects of best management practices, and predict filling rates of reservoirs used for flood control, irrigation, and water supply.
