You've probably heard the adage, "When life gives you lemons, make lemonade!" Missouri has been given some lemons in the form of bighead and silver carp. These large, plankton eating fish, native to Asia, were imported into Arkansas in the 1970s to control water quality in fish farms and sewage treatment facilities. It didn't take long for the fish to escape to the wild, and their...

Air Force Plant 4 (AFP4) and adjacent Naval Air Station-Joint Reserve Base Carswell Field (NAS–JRB) at Fort Worth, Tex., constitute a contractor-owned, government-operated facility that has been in operation since 1942. Contaminants from the 3,600-acre facility, primarily volatile organic compounds (VOCs) and metals, have entered the ground-water-flow system through leakage from waste...

Background Incidence of amphibian deformities have increased in recent years, especially in the northern region of the United States. While many factors have been proposed as being responsible for generating deformities (e.g., contaminants, ultraviolet radiation [UV], parasites), no single cause has been definitively established.Methods To determine whether waterborne chemicals are...

Water-resources data for the 2003 water year for Texas are presented in six volumes, and consist of records of stage, discharge, and water quality of streams and canals; stage, contents, and water-quality of lakes and reservoirs; and water levels and water quality of ground-water wells. Volume 1 contains records for water discharge at 72 gaging stations; stage only at 3 gaging stations...

Purple loosestrife (Lythrum salicaria) is a perennial plant native to Eurasia where it grows along streams, rivers, and wet seepage areas (fig. 1). Seeds were inadvertently brought to North American territories in the ballast water of ships. Purple loosestrife was also intentionally planted throughout North America for its ornamental flowers but has since escaped cultivation to spread to...

The water-use program in Arkansas is a cooperative effort between Arkansas Soil and Water Conservation Commission and the U.S. Geological Survey. During 2000, the amount of water withdrawn from ground- and surface-water sources in Arkansas was estimated to be 10,963 million gallons per day (Mgalld). Of this amount, about 6,952 Mgal/d (63 percent) were from ground water and about 4,011...

Water resources data for the 2003 water year for Louisiana consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground water. This report contains records for water discharge at 76 gaging stations; stage only for 86 gaging stations and 7 lakes; water quality for 56 surface...

Mangrove forests are important coastal ecosystems that provide a variety of ecological and societal services. These intertidal, tree-dominated communities along tropical coastlines are often described as “simple systems,” compared to other tropical forests with larger numbers of plant species and multiple understory strata; however, mangrove ecosystems have complex trophic structures...
