Land in southeast Palm Beach County is undergoing a large-scale change in use, from agricultural to residential. To accommodate residential use, a proposal has been made by developers to the Board of the Lake Worth Drainage District to lower the canal stages in the interior part of the area undergoing change. This report documents one of the possible effects of such lowering. Of particular interes

Lehigh Acres, a residential community with a population of about 13,500 and comprising an area of about 94 square miles (243 square kilometres) in the eastern part of Lee County, has been under development since 1954. Prior to development the area was poorly drained. By 1974, more than 150 miles (241 kilometres) of drainageways had been constructed to drain the area. The water-bearing formation

This report is ninth in a series documenting the annual hydrologic conditions in Dade County, Florida. The hydrologic conditions in Dade County for the 1974 water year (October 1, 1973 to September 30, 1974) except for rainfall are summarized in tables, graphs, and maps. The locations of ground-water data-collection stations are shown in figure 1, rainfall and surface-water stations in figure 2, a

The wood stork is a species of colonial wading bird in the Everglades that is most sensitive to changes in the availability of food. Previous studies have shown that the initiation and success of wood stork nesting depends on high densities of fish concentrated in ponds and other catchment basins during the dry season. The extreme dependence of the wood stork on the cyclic hydrologic regime of the

Construction of the west end of the Cross Florida Barge Canal changed the regimen of the lower Withlacoochee River. The investigation was made to determine how salt water from the Gulf of Mexico moves in the river-canal complex, and how the factors that control salt-water movement--tides and discharge--have changed since canal construction. In the river below the bypass channel, salt water moves i

The presently available data on streamflow, runoff rainfall, and temperature of Puerto Rico are evaluated, although the period of record is very short, with a view to contributing to the knowledge of hydrology of tropical islands. The average annual streamflow in Puerto Rico is 45 percent of the annual rainfall, or 15 percent more than in the eastern piedmont of the U.S. where it is 30 percent. Cl

During the Chilean earthquake of May 22, 1960, intensity 8.5, 4 of 8 wells in Puerto Rico equipped with automatic recorders, recorded seismic fluctuations. The maximum double amplitude, 0.05 ft, was recorded at a well in bedrock near Coamo. Double amplitudes in 3 other wells ranged from slightly less than .01 to .02 ft. Following the Puerto Rico earthquake of Aug. 2, 1961, intensity about 5.5, sei

IntroductionDuring 1950, a series of 43 test wells 30 feet deep were drilled by the United States Corps of Engineers along the western edge of the Everglades from the Tamiami Canal northward to the Caloosahatchee River. The cores obtained from the wells afford geologic data along a line from the lower Everglades of Dade County, where both the geology and water resources have been investigated, to
