The USGS-MWSC partners with various federal, state and local cooperating agencies to implement Monitoring Plans for watershed restoration or protection projects. The purpose of monitoring is to measure change in water quality throughout the duration of watershed specific restoration efforts targeted to remediate specific pollutants of concern. The goal is to document, using defensible scientific...

Short Title: Ozark Karst Study Project Chiefs: Tim Kresse (USGS-Water), Phil Hays (USGS-Water), James Kaufmann (USGS-Geography), Mark Hudson (USGS-Geology), Esther Stroh (USGS-Biology) Cooperator: U.S. Geological Survey Project Time Frame: 2007 - 2011 Three major physiographic provinces in the Ozark Plateaus in Arkansas and Missouri include diverse topography and geomorphology, which greatly...

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...

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 freshwater...

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 of...

Short Title: MERAS Model Project Chief: Brian Clark Cooperator: U.S. Geological Survey Office of Ground-Water Resources Program Project Time Frame: January 2006 - 2009 Fresh ground-water in the Mississippi embayment can be found in alternating formations of sand, silt and clay. Decades of pumping from the Mississippi River Valley alluvial aquifer for irrigation and from the Sparta-Memphis aquifer...

Short Title: Biological Characterization of Louisiana Streams Project Chief: Billy Justus Cooperator: U.S. Environmental Protection Agency Project Time Frame: 2007 - 2009 Information is needed to support water-resources management and decision-making processes for the West Gulf Coastal Plain (WGCP) ecoregion of southwestern Louisiana.

Short Title: MERAS Framework Project Chief: Rheannon Hart Cooperator: U.S. Geological Survey Office of Ground-Water Resources Program Project Time Frame: January 2006 - 2009 A hydrogeologic framework for a ground-water flow model is under development as part of the U.S. Geological Survey (USGS) Ground-Water Resources Program to aid in determining ground-water availability in selected areas of the...
