| Generalized Configuration of the
Base of the Surficial Aquifer System in Broward County, WRIR 87-4034,
figure 35 |
| Abstract: |
This a map showing the altitude of the base of the surficial aquifer system below sea level. In addition to the test holes drilled in this study, eight others from Parker and others (1955) or from the U.S. Geological Survey files were used to select the base. The base of the surficial aquifer system is at a relatively uniform altitude of 150 to 200 feet below sea level (about 160 to 210 feet below land surface) over the western two thirds of the country. The base slopes gradually downward to the east and also into a small depression at the North Everglades east site (G-2315). The base rises to a high area shown as a north-south ridge through the Cypress Creek Canal west site (G-2341) where more than 60 feet of sandy silt was found below the base of the aquifer system. This trend could continue southward, passing near the Markham Park site (G-2321), to the Snake Creek Canal site (G-2317) at the Dade County line. However, the latter test hole was not drilled sufficiently deep to be certain that the base had been reached. A continuation of the ridge-like high area of the base has been recently found to the north in Palm Beach County (W.L. Miller, U.S. Geological Survey, oral comm., 1984). Eastward from this trend, the base slopes downward at 10 to 20 ft/mi at altitude of 300 to 400 feet below sea level along coastal Broward County.
