Water resources data, North Carolina, water year 1993. Volume 1: Surface-water records Water resources data, North Carolina, water year 1993. Volume 1: Surface-water records
Water-resources data for the 1993 water year for North Carolina consist of records of stage, discharge, and water quality of streams; and stage and contents of lakes and reservoirs. This report contains discharge records for 159 gaging stations and stage and contents for 56 lakes and reservoirs; water quality for 54 gaging stations and 5 miscellaneous sites; and continuous daily tide...

Effects of water-control structures on hydrologic and water-quality characteristics in selected agricultural drainage canals in eastern North Carolina Effects of water-control structures on hydrologic and water-quality characteristics in selected agricultural drainage canals in eastern North Carolina
November of water into and out of tidally affected canals in eastern North Carolina was documented before and after the installation of water-control structures. Water levels in five of the canals downstream from the water-control structures were controlled primarily by water-level fluctuations in estuarine receiving waters. Water-control structures also altered upstream water levels in...

Seagrasses, dredging and light in Laguna Madre, Texas, U.S.A. Seagrasses, dredging and light in Laguna Madre, Texas, U.S.A.
Light reduction resulting from maintenance dredging was the suspected cause of large-scale loss of seagrass cover in deep parts of Laguna Madre between surveys conducted in 1965 and 1974. Additional changes to 1988, together with an analysis of dredging frequency and intensity for different parts of the laguna, were consistent with this interpretation. Intensive monitoring of the...

Estimated freshwater withdrawals in Texas, 1990 Estimated freshwater withdrawals in Texas, 1990
This report presents 1990 freshwater withdrawal estimates for Texas by source and category. Withdrawal source is either ground water or surface water. Withdrawal categories include: self-supplied irrigation, thermoelectric-power generation, water supply, industrial and mining, and other (domestic, commercial, livestock). Withdrawal data are aggregated by county, major aquifer, and...

A summary of water-resources activities of the U.S. Geological Survey in Iowa, fiscal year 1994 A summary of water-resources activities of the U.S. Geological Survey in Iowa, fiscal year 1994
Water-resources programs and activities of the U.S. Geological Survey in Iowa consist principally of hydrologic data collection and investigative studies that address water-resource issues. The work is supported by direct Federal funding, by transfer of funds from other Federal agencies, and by joint-funding agreements with State or local agencies. The Iowa District of the Geological...

The relationship between species richness and community biomass: The importance of environmental variables The relationship between species richness and community biomass: The importance of environmental variables
Several studies have used plant community biomass to predict species richness with varying success. In this study we examined the relationship between species richness and biomass for 36 marsh communities from two different watersheds. In addition, we measured several environmental variables and estimated the potential richness (the total number of species known to be able to occur in a...

Intraspecific variation in the response of Taxodium distichum seedlings to salinity Intraspecific variation in the response of Taxodium distichum seedlings to salinity
Seedlings of 15 open-pollinated families of baldcypress (Taxodium distichum) were tested for their tolerance to combined salinty and flooding stress. Ten of the families were from coastal locations in Louisiana or Alabama, USA, that were slightly brackish. The other families were from locations not affected by saltwater intrusion. Five salinity levels were investigated--0,2,4,6, and 8 g...
