| Configuration of the Base of the
Biscayne Aquifer in Dade County, WRIR 90-4108, figure 16 |
| Abstract: |
The base of the Biscayne aquifer are shown in this map. Near the western
limit of the Biscayne aquifer, the base is about 20 ft below sea level
and then slopes downward to the east at an average of about 3 to 4
ft/mi, forming a wedge-shaped aquifer. In coastal southeastern Dade
County, the base is 100 to 120 ft below sea level, but in coastal
northeastern Dade County, a basin or trough reaches a depth of at
least 187 ft below sea level. However, this basin is not as deep as
the basin in eastern Broward county where the base reaches depths
of more than 300 ft below sea level (Fish, 1988, fig. 37). Data and
contours from the map of adjacent Broward county were considered along
with the new Dade County data for the preparation of this map. An
unusual configuration occurs along Tamiami Trail near State Road 27 (SR-27) because a thick section of highly permeable limestone in the
upper part of the Tamiami Formation in that area is included in the
Biscayne aquifer.
