Altitude of the water table in the alluvial and other shallow aquifers along the Colorado River near La Grange, Texas, December 1980
The water-table contours on this map were constructed from water-level control derived from an inventory of springs and wells in the area, U.S. Geological Survey topographic maps, and from data presented by Rogers (1967). Because of the available water-level control and the rough terrain throughout the area, the delineation of the water table was limited to 20-foot contour intervals. On the basis

Approximate altitude of water levels in wells in the Chicot and Evangeline aquifers in the Houston area, Texas, spring 1981
The purpose of this report, which was prepared in cooperation with the City of Houston, the Harris-Galveston Coastal Subsidence District, and the Texas Department of Water Resources, is to show the altitudes of water levels in wells in the Chicot and Evangeline aquifers in the Houston, Texas, metropolitan area. The maps are based on water-level measurements in 1981 in about 500 wells.

Hydrologic data for urban studies in the Austin, Texas, metropolitan area, 1979
This report contains rainfall and runoff data collected during the 1979 water year for the Austin, Texas, metropolitan area. In 1975, the program was expanded to include the collection of water-quality data. In 1978, the program was expanded to include a groundwater resources study of the south Austin metropolitan area in the Balcones fault zone. The information will be useful in determining the e

An observation-well network concept as applied to North Carolina
A statewide observation-well program is proposed for North Carolina based on four networks of observation wells with different but clearly-defined objectives. These are referred to as the (1) climatic-effects network, (2) terrane-effects network, (3) local-effects network, and (4) areal-effects network. The characteristics of each network are related to natural and manmade stresses in aquifers, an

Relation between freshwater flow and salinity distributions in the Alafia River, Bullfrog Creek, and Hillsborough Bay, Florida
Data on streamflow, tide stage, specific conductance, and chloride concentration were collected in the Alafia River and Bullfrog Creek to describe the salinity and physical characteristics of the saltwater wedge. The location of the saltwater-freshwater interface for both streams was described by multiple regression equations involving streamflow and tide stage. Low-flow frequency data were used w

Hydrologic data for urban studies in the Dallas, Texas, metropolitan area, 1979
Hydrologic investigations of urban watersheds in Texas were begun by the U.S. Geological Survey in 1954. These studies are now in progress in Austin, Houston, and San Antonio. The study for the Fort Worth metropolitan area was completed at the end of the 1978 water year, and this report is the last annual report for the Dallas metropolitan area. Hydrologic data contained in this report and all pre

Proposed observation-well network and ground-water level program for North Carolina
An initial system of 223 observation wells is proposed for monitoring ground-water levels in North Carolina. These wells are suggested to replace and upgrade nearly 650 observation wells currently measured in separate State and Federal programs, and are arranged in four groups or networks each having specific objectives. These groups are (1) a climatic-effects network, (2) a terrane-effects networ

Manual for leveling at gaging stations in North Carolina
This manual was prepared to serve several purposes in the U.S. Geological Survey North Carolina District. This manual sets forth District policy as to frequency of levels, accuracy criteria, procedures for checking the datum and setting of the various types of gages, general rules to follow in establishing the original datum of a gage, and contains sample notes to be used as guides in level noteke

Ground-water data for Georgia, 1980
More than 2,000 water-level measurements made in Georgia in 1980 provided the basic data for this report. Daily mean water-level fluctuations and trends are shown in hydrographs for the previous year and fluctuations of the monthly mean water level are shown for the previous 10 years in selected observation wells in Georgia. Monitoring ground-water levels is essential to the understanding of stora
