Water Resources of Louisiana’s Parishes

The USGS is summarizing basic information on water resources for each parish in Louisiana and presenting the information in fact-sheet format. Information presented includes groundwater and surface-water availability, quality, development, use, and trends. These brief summaries of water resources will provide parish officials, local officials and concerned citizens with information needed to...

Historical Preservation of Toomer's Oaks in Auburn, AL

The live oaks framing Toomer's Corner in Auburn, Alabama were planted about 1880 and have served as a focal point for Auburn celebrations in recent decades. The trees recently received a powerful dose of an herbicide known as Spike 80DF. In an effort to save the trees, a task force made up of university horticulturists, landscapers, agronomists, engineers, chemists and others has undertaken a...

McKenzie River Source Water Study

Drinking water for the city of Eugene, Oregon, is drawn from the McKenzie River, a high-quality source that is nonetheless threatened by urban, agricultural, and forestry land uses upstream as well as by changes in water management in the watershed. In 2002, the USGS began monitoring dissolved pesticides in the McKenzie River and its tributaries.

Coastal Plain Culvert Study

Various environmental groups in Alabama are concerned that the use of culverts at highway crossings to convey stream flows has detrimental effects on the natural conditions of streams. Specifically, some groups are concerned that changes in stream geomorphology, sediment concentrations, and associated turbidity adversely impact the benthic macroinvertebrate community when culverts are...

Assessing the Influence of the Davis Pond Freshwater Diversion on Water-Quality in Waterways and Marshes of Barataria Preserve

In 2002, the Davis Pond Freshwater Diversion began diverting up to 10,000 cfs of Mississippi River water into the waters surrounding the Barataria Preserve of the Jean Lafitte National Historical Park and Preserve. Previously, precipitation, local surface-water runoff, and occasional marine intrusion largely determined quality of surface and marsh porewaters at the Preserve. The new influx of...

Physical soil properties of wetlands, and the hydrology of tidal swamp, tidal creeks, adjacent rivers, and adjacent marshes along the coastal gradient of palustrine, oligohaline, and mesohaline sites in relation to drought, storm, and tidal events

The LaWSC, in collaboration with researchers from the National Wetlands Research Center (NWRC), the NRP program, Auburn University, and Clemson University, is documenting conditions in tidal swamps in Louisiana, Georgia, and South Carolina as a baseline with which to compare future data to assess the impacts of climate change in such areas. Tidal swamps in these states offer an array of...

Water quality monitoring in the Mississippi River Gulf Outlet, the Gulf Intracoastal Waterway, Lake Borgne, and adjacent waterways in southeastern Louisiana, 2009 to 2013

In early 2009, the U.S. Army Corps of Engineers (USACE) constructed a rock barrier across the Mississippi River Gulf Outlet (MRGO), a navigation channel between the Port of New Orleans and the Gulf of Mexico. In August 2008, prior to construction of the rock barrier, the LaWSC, in cooperation with the USACE, began monitoring specific conductance, dissolved oxygen, and discharge in the MRGO to...

Assessment of water quality and soil conditions at the Bayou aux Carpes 404(C) property wetlands

Wetlands in the Bayou aux Carpes area, south of New Orleans, La., currently are isolated from direct inflow of storm water runoff by levees and spoil banks. The USACE is considering removal of a spoil bank that would allow storm-water runoff to flow through and across the wetlands. . The wetlands consist of floating marshes, with a predominately organic substrate, and forested wetlands, some...

Simulation of Groundwater Flow in the "1,500-Foot" and "2,000-Foot" Sands and Movement of Saltwater in the “2000-Foot” Sand of the Baton Rouge Area, Louisiana

Saltwater encroachment has been detected in six aquifers, including the "1,500-foot" and "2,000-foot" sands, north of the Baton Rouge fault in East Baton Rouge Parish. The encroachment is in response to ground-water withdrawals, primarily for public supply and industrial uses, in Baton Rouge. Additional information is needed for water planners and managers in the Baton Rouge area to make...

Water Use in Alabama, by Watershed, 2005

Water is one of the most important of Alabama's natural resources. Water is not only a vital component of human existence, it is critical to the overall quality of life. In order to protect and preserve this resource for future generations, we must have a baseline of information to make decisions. Decision and policy makers must know the answers to three fundamental questions: where is the...

Water use, by category of use, in Alabama, 2005

More surface water than ground water was withdrawn for all categories except aquaculture, mining, and self-supplied residential. During 2005, estimated withdrawals by category and in descending order were: thermoelectric power, 8,274 Mgal/d; public supply, 802 Mgal/d; self-supplied industrial, 550 Mgal/d; irrigation, 161 Mgal/d; aquaculture, 75 Mgal/d; self-supplied residential, 39 Mgal/d;...
