Configuration of the Base of the Gray Limestone Aquifer in Dade County, Fl, USGS WRIR 90-4108, figure 15

Contours of the altitude below sea level of the base of the highly permeable gray limestone aquifer in the Tamiami Formation are shown in this map. The aquifer, as mapped, includes all intervals of the gray limestone that are at least 10 ft. thick and have an estimated hydraulic conductivity of at least 100ft/d. The contour interval is 10 feet.本地图展示了泰米亚米组（Tamiami Formation）中高渗透性灰色石灰岩含水层底板的海平面以下海拔等值线。本次制图所界定的含水层包含所有厚度至少10英尺、估算水力传导度不低于100英尺/天的灰色石灰岩地层段。该地图的等值线间距为10英尺。
